    180g mixed reef
  1. Looking to change lighting from a pair of Kessil AP700s to the aquaticlife T5 hybrid with the kessils attached to it. In order to do that though I'll have to switch from tank-based brackets to a wall-mount system. The tank sits 16" away from the wall so I need to extend to about 28" away from the wall to the center of the light. If anyone has suggestions on a vendor I'm all ears but I haven't found anything yet. So I'm looking custom/DIY. Thinking this kind of thing would be easiest... Does anyone know where I can find aluminum bar like this? And maybe somewhere to get it bent appropriately? I figure a couple of those mounted to the studs would do the trick.
  2. Yep, of the ~200lb of rock in there, about 3/4 of it is realreef, the rest is long-established rock from my previous tank. Some of it had been wet for 10+ years. Also have a marine pure brick in the sump.
  3. No pests that I've seen. Even when the monti started to die it was in quarter-sized bleached spots that spread...nothing visible in those patches, but that just screamed pest of some kind. But then the cyphastrea went from the top-down. Just messed up. 😕
  4. Maxspect Gyres on either end running on the tidal cycle. Dual jebao gyres on the back wall facing forward full-blast. One 200gph powerhead low-back to wash across the back base of the tank behind the rockwork. Should be tons of flow in there. I haven't tested PAR readings in awhile, but stuff had been thriving for a long time. _Something_ has to have changed, but I'll be damned if I can figure out what. 😕
  5. Hey all, I could use some insights. In 25+ years in the hobby I've never seen a tank do this and I can't even come up with ideas of what could be going on. Details... 180g tank up for just over a year Couple hundred lb live rock Kessil AP720, Ca reactor, Pentair UV, Simplicity skimmer. Water has been very stable, testing weekly or semi-weekly with Salifert kits. Typical parameters: Ca: 435 Alk: 8.5 - 9.0 Mg: 1400 Sg: 1.025 NO3: 0-2ppm PO4: 0.02 Just had an ICP done and all is confirmed. Only thing registering as not normal range is Molybdenum -- 0.001 above normal range (so basically high-normal). So according to the numbers and equipment this should be a textbook show tank. And indeed acans and most soft coral thrive. Acans look like somebody inflated them like beachballs. But here's where it gets weird. Most SPS go STN within two weeks of going into the tank. This is a relatively new development, within the last 2-3 months. I had a monti that went from a chip the size of a quarter to a multi-layered dinner-plate in under a year. And then STNed within two weeks. A cyphastrea that took over an entire rock...same thing. Died from the top - down over the course of two weeks. New 'canary in the coalmine' SPS looked good for a couple days...then STNed. But I've got some random purple birds-nest kind of thing that isn't growing, but is as fuzzy and polyped out as ever. I'd think lighting because the cyphastrea dying from the top-down. I'd think some kind of bacteria or pest because of how the monti started dying in patches that spread. But nothing had really changed with the tank in quite awhile, so I'm absolutely baffled. No fish changes, nothing in there predating on coral. Just at a loss. Any ideas of other things I can check or try??
  6. I'll be there +1. First event besides the big frag swap last spring; looking forward to meeting everyone! Not much on the pitch-in list...any requests of something to bring?
