Well,

I was going to set up my 33 gallon as a reef. I have decided to put this on hold for a little bit. I have the 33 gallon. I also have few other pieces, a 700 gallon overflow kit, a mag 7 pump, a reef octopus rated for 250 gallons(I know), and some other odds and ends.

A buddy of mine has a 72 gallon corner bowfront that he has had for about two and a half years. Like all of the corner aquariums, lighting them properly can be tricky.

There is not much room is place lights and yet it has to be bright enough to punch to the bottom of his aquarium.

What he had been using with some success was several T12-VHO lamps. He had two 3' 95 watt lamps in the ...

When the Vortech pump starts rattling, the first thing to do is realign the motor with the wetside. If it goes back to silent, that's perfect. However, over time, the rattle may return and refuse to go away. When this happens, you need to replace a small part inside the wetside.

I had this problem recently with one MP40w, and obtained some new parts prior to beginning this little project. Having a local fish store with parts is ideal, but if you can't do that, they are now available ...
