    Cyanobacteria, ugh.

    LOL, it never occurred to me to post a picture of clean sand I didn't take a "before" picture. I'll try to remember for future threads, though I hope I don't have to repeat this process any time soon.

    Just a follow up. It’s been a few weeks and the tank is still looking great. No problems with livestock. Chems are all looking fine. Thanks again to all for the advice.

    Cyanobacteria, ugh.

    Good to hear. Does anyone here know why the water change right after treatment is called for? Obviously the antibiotic isn't harmful to the occupants of the tank, and it kills the Cyanobacteria, yet what I've read says to do a large water change right after the treatment. Just wondering why.

    Well things are looking really good 48 hours in. No live Cyano anywhere that I can see. Some brownish patches that look like dead bacteria but the rest is nowhere to be seen. Hurray! Thanks to all for the advice. Tomorrow will be the 25% water change. I hope there’s no harm in waiting an extra half day, it’s too late to do it tonight.

    I gave it the first dose of Cyano RX Sunday afternoon. By the morning things looked a lot better. There was still some hanging around though, so we'll see what this afternoon looks like. I may need to do a water change and re-dose.

    Cyanobacteria, ugh.

    Fair point there. I'm going by descriptions on the internet so... This is a magenta colored substance that is covering my sand, and now some of my rocks . It started out looking like a coloration to the sand, kind of the way coraline colors rocks, but after awhile it got thicker and if left in place it forms a wispy looking dark film on the sand which then begins to creep up the sides of the tank. When scraped or moved at all it turns out to be very thin and condenses into small strands which are fairly heavy and don't float in the water column very long without a lot of water movement. It's difficult to vacuum up because of this "weight". After stirring or siphoning the sand it looks clean except for where these strands land, but within a day it begins to pink up again and spreads rapidly over the sand within a week. I could take a picture, but I'm not sure how easy it is to ID from a photo on the internet.

    Sorry to hear about your corals! OK. I'm looking for an actual cure. Had I realized what this was at the beginning the Peroxide would likely have worked great, but at this point? I don't have any coral (FOWLR for the moment), so no issues with that either way. I'll dump the sand, it's not a big deal. Thanks.

    Does the H2O2 require a post-use water change like the antibiotic treatments do? Any other special handling/considerations? I'm thinking I might like to try this first.

    OK, so here's the next question that I want to answer before I do any sort of dosing of the tank: Over the past few weeks I've taken around a gallon of "top" sand off the bottom, basically trying to capture and remove some of the cyano. It made a minor dent in the stuff but didn't last long. Now however, I have a little Easter bucket full of tainted sand. So do I: Put the sand back and then treat the tank? Treat the tank and somehow treat the sand separately? Toss the stuff and suck it up; it's only a bag of sand!

    Now that's what I like to hear! Thanks.

    Cyanobacteria, ugh.

    Wow. That sounds kinda scary, but I'd love to be able to dose this stuff out without hurting the fish. H2O2 is safe for fish, inverts, coraline, etc.?

    Cyanobacteria, ugh.

    Thanks. It’s good to know that I’m at least on the right track. I’m reluctant to go blackout and food free for so long... the fish look at me with those pleading eyes... : P Seriously though, I thought I read that Cyanobacteria doesn’t respond to low light the way algae does. Does it still help?

    Just when things started to calm down on the noisy drain front; this. lt started as a few little pink specks in the sand. I naively thought nothing of it; just another colorful bit to the saltwater aquarium. yeah. Now it’s everywhere. Covering the sand, on my live rock, up the glass. I’ve been siphoning and stirring up the sand. I’ve added filter socks to catch what’s stirred up and then remove and clean them. I bought a Gyre to increase flow but ended up dialing it back to 10% flow most of the time because more looked like a storm at sea and sent the fish running for cover in the rocks. I’ve tried to minimize the amount I’ve been feeding them (they always behave like they’re starved but I don’t think they are. I checked alkalinity and it’s over 8. Other numbers seem fine. l’m wondering what the prognosis is. I assume I’m not the first to go down this road, what did you all do and how effective was it? Thanks

    Full siphon drain on non-drilled tank?

    Time for an update. Things are finally quiet in the tank. The solution for me was a combination of Lifereef silencers (a tuned standpipe cover) and reduced flow. I would like a bit more flow but it is what it is and it’s quiet, which is fine for now. I’ll start a new thread on the next, and possibly related issue. Thanks everyone.
  15. 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.
