As a supplement, PC might be OK. T5 is going to give you more PAR for the wattage, though. T5 also has a much better selection of bulbs from...
I would put a sponge as a prefilter if they're clogging up on you. You really need the sponges in the chambers; they hold the media.
Nerites don't hatch in saltwater; they need the salinity to be lower.
Yep, it goes on the inside. The "don't tighten too much" advice is good too. The acrylic could also crack if you do.
It could also be that they're the wrong shrimp, lysmata californica, instead of lysmata wurdemmani.
Barnacles are only bad if they're on the underside of your boat or in the intake of your nuclear reactor ;D
Chemicals don't do anything to help your cycle, and neither does base rock. Only live rock can keep you from having a full cycle, but there's still...
That's quite a nice tank. Definitely not something you see every day, which makes it all the more intriguing.
Carbon needs to be changed every 2 weeks, but GFO can last anywhere from 4-8 weeks depending on how much phosphate it pulls out.
It's absolutely true. The problem with MH, T5 and all other lights is that there's physical wear and tear. There's heat, which degrades a substance...
You probably could. You might want to change the fittings to a larger size, though.
It could have happened. Not sure if it's likely.
It's always best to start low and work them up to their final location, unless you know the lighting conditions of the tank it came from in detail.
Mine jumped out of a 1" round hole while in a covered QT. It did decorate, though. It also freaked out constantly because the tang I had kept going...
Are you sure it was eating the coral and not some detritus/algae/other growth on it?
All you need for fresh is somewhere to put carbon, and a source of mild water movement. I would go planted, so you don't need GFO or anything like...
Usually when they're small, they grow out from the edges. When the colony gets to a decent size, it starts more "up and out" type growth, which gives...
Favia are some of the corals you would label "brains". I would say favia maxima.
I would raise it. In planted tanks, you should shoot for as little surface movement as possible, since you want a bit more CO2 than your average FW...
It may be an aluminum oxide, as that's another fairly common phosphate remover.
