I read somewhere, "The solution to pollution is dilution"....

I only used cement. I would say I used a generous amount, but its not dripping everywhere or anything...I've never seen the stuff stay liquid for more than a few seconds when working on piping..but my one overflow box did have some water in it and one joint may have got wet before it set (replaced a plug in the bulkhead with an adapter)...thats what really worries me

Things have settled down now. The best I can figure is that the fish were freaked out by the noise (and possibly flow) of the new "quiet"one 6000 return pump. I swapped it out for a 3000 (much quieter) and they went back to normal behaviour. My poor bicolor must have had underlying issues...although he looked healthy and robust only a few days before I haven't seen him for 2 days. The long term plan is now to get another 3000 and have twin return pumps. The 6000 can be sold to someone who doesn't mind enjoying their reef while wearing earmuffs...
