Hey all :yeahdude: I am new to this site so here goes the first post of hopefully many 26th September 2013, the day I bought my Boyu TL 550 as my smaller cube wasn't cutting the mustard. The tank is completely stock, no upgrades have been made to the tank. I am using water from the 2 Oceans Aquarium in the waterfront, so far the water has been good, salinity has been a touch low at 1.021. Been having slight pH troubles as well, but then I tested it at night and the difference of pH from morning to night is clear. My project is to have a reef dominated tank with a few fish, but softies have my attention big time. I also love my inverts. Livestock is as follows: 2x Cleaner Shrimp 2x Peppermint Shrimp 1x Sexy Shrimp 2x Neritas Grazer Snails 1x Bumble Bee Snail 1x Limpet 1x Porcelain Crab Softies: 2x Zoad frags 1x Xenia 1x Euphyllia Fish: 0 So here is a picture of it after 2 months My lovely euphyllia but not so happy (for the time being) xenia 2 cleaners and a bumble bee hitch hiker Question. Is the placement of the powerhead justified? I placed it there to create flow directly onto the back rock for filtration and minimize dead spots behind the large amount of LR I have.
