Thanks so much for the advice. I think the QT tank with hypo is the way to go. From what I've read, hypo is generally less stressful for the fish as compared to using copper sulfate. I'd consider using hypo in my main tank, but I already have a fair number of inverts (crabs and snails) wandering...

Over the last several months I've gone through setting up my 75g tank (w/40 gallon sump), adding LR and livesand, and cycling the tank. I added a variety of inverts (crabs and snails) on Wed and today (Thu), I added my first fish: two very small tangs (a yellow and a Kole yellow eye) after 2...

Great, thanks for the ID. That was my thought as well. The only thing that made me a bit unsure was that the picture of the porcelain crab showed a crab with a fair amount of color variation on the body, whereas the crab in my tank is (more or less) a solid blueish grey. But given that it has...

Over the last 1.5 months or so I've cured my live rock, placed it into my tank, and let the tank cycle (using the dead shrimp method). Today, I finally added some inverts (hermit crabs and snails) and of course as soon as I did this, I noticed a crab which had until now, gone un-noticed. Now I...

I finished the plumbing from my sump to the tank last week (all PVC) and until day, everything was running fine (i.e., there were no leaks). Then, when I was playing around with equipment in the sump, I noticed a slow leak at the base of the CPR overflow. To be clear, it is not leaking at any...

Great. Thanks for all the advice. I think I'll go ahead and get the Mag 9.5 and throttle it back if necessary.

I am in the process of setting up a 75g reef tank. I currently have 3 Maxi-Jet 1200s (300 GPH), an overflow that is rated at 800 GPH, and a sump that will probably hold around 20 gallons. I'm guessing that the total system size will be 85 gallons. Other posts suggest that I should be moving 10...

I hate to ask a stupid question, but what exactly is a ball valve?

I'm in the process of converting my 75 gallon freshwater tank to a reef tank and am in need of a pump recommendation for my 40 gallon sump. I'm using the CPR CS100 overflow (800 GPH) and from reading past topics, I know that my pump should not return more than 800 GPH back to the tank. The tank...
