Hi all! I have a Landen 26g AIO and I recently added IM custom media caddy fuge in the middle chamber which almost fits perfectly. I have a copepod hotel/motel/holiday inn ;) on the bottom rack and above it have a ball of chaeto powered for 12 hours by a JBJ 4W white light. It was growing...

Hello all, I am an engineering student and I also am into reef keeping like the rest of you. I would like to cultivate phytoplankton for my tank and I also need to go through the design process for a project so this post is for asking "consumer" (people that have experience cultivating...

Im putting together a full time 40 breeder to have as a quarantine for new fish and to treat any sick fish. So I’m curious to know how many people keep a full time hospital tank/ Quarantine tank and do you keep dry/ cycled rock in it. Or do you keep some sort of sponge filter to house the...

Hi guys, I have this leptastrea I bought a few weeks ago but don’t know the breed. Could someone Identify it please? Thanks in advance! Sorry for the bad pic I’ll have one under witch light in the morning

Two weeks ago I made the worst mistake to date when it comes to my nano. I went to dose my iodine (Lugol's) and did 2 drops instead of one. Then I dose double the amount of trace elements. I had planned to do a 20% WC the following morning. It seemed to be too late. My zoas, green stars, lepto...
