  1. I'll check with Premium. My drain lines are 2x1". Did you put your valves at the end of the drain, or in the middle somewhere? I suppose it doesn't matter since the effect would be about the same.
  2. No, they go into filter socks in the sump but there is nothing to control the outflow. I see where you're going on this. What type of valve would you put on there? Ball valves are rather imprecise and gate valves are really large.
  3. BTDT. Twin Stockman standpipes actually. Half a dozen variations. None worked. The trouble seems to be balancing the flow on a twin drain. If they’re out of balance, one ends up pulling down too far and sucking air under the cap then surging back and forth. Even with almost equal plumbing it’s hard to get them tuned just right and it seems like it’s very sensitive to any variation. I think that with a single drain it would be easier to make work, but I can’t find one with a high enough flow rate and a single drain. Besides, I like the idea of two drain lines for some redundancy.
  4. Full siphon drain on non-drilled tank?

    Thanks for the encouragement and sharing your rough start Pete. I’m still working on it, and in fact have gotten the drains to be silent most of the time with a weird combination of eshopps’ original standpipes, a drilled 1” PVC cap with airline propped at an angle on top, and a lower return pump setting. This temporary kluge will not work for the long run but demonstrates that it is theoretically possible to get this tank configuration to work quietly. I’m waiting for some parts which will hopefully make it a more permanent solution and allow me to increase the flow somewhat. It’s OK now, but It feels like I’m right on the edge of the flushing and sucking. My fingers are crossed, but for now things are looking up. Thanks again to everyone for the advice and support.
  5. Full siphon drain on non-drilled tank?

    Ryan, thanks for the perspective. I can safely say that my issue at this point is entirely noise. Flooding is not an issue in my mind for two reasons: First, I have a level sensor on the display tank that will shut off the return pump if it gets too high, and second the return compartment of the sump that I'm using is too small to overflow the display tank anyway; it'd run dry before that, so I'd fry my pump but not flood the floor. My next step will be to add a level sensor to the sump so that the pump will shut off if the water level gets too low. I agree that drilling a filled tank isn't going to work. I hadn't thought about the pressure/cracking possibility, but in my case the tank is too close to the wall to go at it from the outside and I don't think drilling from the inside out, with coolant and shavings and whatever else possibly getting into the tank, would end well either. I don't like sounding lazy, but yes the easiest solution that keeps everything working is what I'm shooting for. I've already been in contact with Lifereef and have a plan of attack on the noise. I'll let you all know if it works. Thanks.
  6. Full siphon drain on non-drilled tank?

    OK, so then maybe I can partially drain the tank and drill the back, if it's not tempered. If it is, then it explodes and dumps around 125 gallons of saltwater and all of my fish into the living room... Not loving that idea, so back to taking the tank down... or not. I've done a little looking around at drilled overflow boxes and my immediate question is "what do I gain?" The drilled overflow boxes look exactly the same as my present box minus the siphon tubes; they have the same fittings at the bottom where the plumbing connects, the same standpipes inside the box. I get that the siphon overflow isn't the best choice from a failsafe perspective, but that's not my issue, and I'm not willing to drill the tank just to eliminate that (to me) small risk. So I come back to my original problem: noise in the drain and large bubbles in the sump, and I have to ask: Will a drilled overflow box make either of those any better, or is it just the same "maybe" and trial and error tuning as with any other overflow box?
  7. Full siphon drain on non-drilled tank?

    Yeah, to be fair nobody said it was going to be cheaper than fresh, just "easier" to maintain. So I suppose that taken in that context they weren't incorrect or deceptive, I just didn't get the full picture. I've heard the "it's easier" song from multiple places so I'm not going to point the finger at one. From a "putting in the work" perspective, I've been willing and have done a lot of work, it just turns out that it's been largely wasted effort which is disappointing. I've also spent a ton of money on this project and thanks to my ignorance have the wrong tank and stand (no side opening for a sump and smaller than needed doors on the front). I have four fish, a shrimp, a star, and cleanup crew (snails & emerald crab that came with the live rock). Caring for these while emptying the tank and making the needed changes is a big concern, though given adequate resources it's obviously do-able. Is there an "ideal" configuration for a drilled tank as far as hole placement, etc.? I'd like to not make any more mistakes, or revisit this process if I choose to go that route. For example: Bottom drain vs side drains, return via bulkhead? How many holes, and where would be my question. Then of course there's the risk of breaking the glass and ending up with no tank and a Tupperware bowl full of fish looking at me like WTH? I just feel exhausted. I wanted to be done with setting up the tank long ago and now I'm faced with tearing everything down, drilling and starting over. I don't know if I have it in me. And on top of that I'm not at all convinced that the day-to-day care and maintenance is going to be anywhere near as simple as my old freshwater tank was, which was part of the idea going in. All of this is my fault for not doing my homework first. My only excuse is that I didn't know that there was so much more to know. I appreciate the advice and encouragement. My decision right now is whether to move ahead with the sump or not. I have a large canister filter that I was using before getting the sump and I can go back to that, which would get me silent operation with minimal fuss and I could forget about all of this for awhile. The downside is that I'd need to start performing frequent water changes on a 150 gallon tank which I dread the thought of (I didn't enjoy them on my 35 gallon tank), but at least I'd have a couple of weeks of not messing with the tank in between. If I were to drill this tank what does the process look like? I assume I'd need to set up a temporary tub of some sort with basic life support for the livestock and rocks. I don't imagine that keeping the water is practical though it would be easier and faster if I could. I also imagine that I and probably two other people would need to take the tank off of the stand to drill it (remove the sand for weight too I assume - another container). This thing is really large and heavy. The drilling is probably the least of the process, though obviously it's important to get it right. Then put in some bulkheads and reverse the process, adding appropriate piping along the way. Do I have the right idea? How long should I expect this to take (my wife will be curious to know). Thanks again for the expert advice.
  8. Full siphon drain on non-drilled tank?

    Thank you, I appreciate the advice although it's the last thing that I wanted to hear. I'm going to have to give this a lot of thought, as my investment in time, energy and money to this point is so far beyond what I had intended that I'm not sure that I'm willing to start over. This all began when a 35 gallon freshwater tank started a slow leak. I was on the verge of donating the fish and walking away because I was tired of water changes and upkeep on that incredibly simple tank. I was drawn in by a sale on tanks and decided to give it another shot when the inevitable "have you ever thought about saltwater" question came up. I figured that if I was going to continue it might as well be with something I had always admired and wanted. The "it's easier than fresh" nonsense sucked me in. In retrospect I should have known better; If it sounds too good to be true... I've now spent a month of weekends setting up, measuring, cutting and gluing PVC, buying insanely expensive stuff, changing stuff, testing stuff... All I wanted was some beautiful fish to enjoy. I'm now spending all of my free time trying to keep this tank running. Apparently there's a fine line between a dream and a nightmare. I'm walking that line at the moment. I do appreciate the advice. I just need to think about what I'm going to do.
  9. Full siphon drain on non-drilled tank?

    Thanks. Obviously not what I want to hear, but sometimes that's the way it goes. Honestly I think before I went to the trouble of tearing the tank down and starting over I'd hook up a canister and just live with that. I already have one that I was trying to "upgrade" from. I don't like the idea of a flood at all though, and while I've taken precautions with a siphon tube overflow, level sensors, and sump markings I realize that the risk can't be completely eliminated with a HOB overflow. This was intended to be a relatively easy upgrade from freshwater. Everyone at every LFS I've ever spoken to said "saltwater's easier than fresh". Yeah, right, and it's cheap too I'll try to make the frag swap. Thanks for the help.
  10. Amazing. I have exactly the same overflow, similar sump, and opposite problem. My drain inlets are insanely loud with the OEM down tubes and sponges. I don't know if the sump side is quiet or not because I can't hear it over the roaring, sucking sounds from the overflow box!
  11. Greetings all, new member here and I need some help with a noisy overflow. Confessions up front: I didn't do enough research, trusted my LFS too much, and ended up with a beautiful undrilled 150 gallon tank and a stand with no side opening. Needless to say, setting up any sump was a bit of a task, but I managed with a small Trigger 26 fed from an eshopps PF-1200 HOB overflow. I have the overflow plumbed to the sump via 1" flex PVC, with one side going to the built-in sump drain and the other going to a Sock-It in what was supposed to be the skimmer section of the sump but is now just for the return and maybe for a small refugium in the future. The issue from the start has been noise. Doing some research I put together a pair of Stockman standpipes which individually work quite well. The problem is that with two of them sharing the overflow, it's almost impossible to get them to drain evenly and when they do not I get the flushing/surging effect complete with loud belches of bubbles into the sump and a nasty sucking sound from the overflow when the overflow's water line drops below the entry of one or the other. Not great for the living room where the tank is set up. Through trial and error and a great deal of luck I've managed to get everything mostly stable and now it just sounds like your standing at the beach (most of the time). I can live with that. However, it is incredibly finicky; it will go for a couple of days and then flush and slurp again. The water level in the sump will be steady and then it'll change when the overflow changes and drive my skimmer and ATO crazy. I can play with it and get it to behave again, but I as it is I can't leave it alone and I just don't want to have to keep fiddling with it. My wife recently asked why not a full siphon from the overflow tubes. I think the answer is that if the return pump stops, the overflow will drain until it breaks suction and then won't restart when the return pump comes back on, is that correct? Otherwise obviously it would be the "perfect" solution for a quiet system. Another option would be a return with a single, large pipe rather than two smaller ones, but I don't see any that are that big. My return is 1.25" diameter, so 2x1" is overkill, but 1" is smaller than I think I should go. Could I drill out a larger hole in a single drain overflow? Would that make sense? Again, I don't know enough to answer the question. I'd like to not have to throttle back the return pump too much (it's a Varios 6 set at about half speed right now) just for water flow and oxygenation. So, what do you all recommend? I know that if I could go back in time I'd have bought a drilled tank for one, but that's not a practical option at this point. What can I do with a HOB overflow for a 150 gallon tank that will be reasonably quiet? Thanks. John
