    Hey guys, I have had a candy cane acan coral for a little while now. I have been playing with it, moving it around my tank. I can't quite get the perfect spot. It is on a fraq plastic piece so it is hard to find a spot. It is in the sand and has fluctuated from being really small to really...

    Real quick background. I recently upgraded my tank from a 90 to a 180 (6 months now) old tank was a little tricky to keep my levels stable in, so as a result the corals, mostly sps, did not have the best colors. they wern't so much brown, they are just not vivid. I had them under 400W MH's which...

    I had been running a Corallife MH on-back of tank (15K, 150W) for a couple years. I had six corals doing great. I finally replaced the bulb and the tank crashed from the new bulb. I mean I lost all coralline algae, the rocks went white etc I had moved the coral to the bottom and raised the...

  12. The THINK Tank
    I've been reading....and can't for the life of me remember where I read an article or something about dying corals on coral reefs...the article stated that there was a new belief that some of the corals that were thought to be dead were not actually dead but pulled inside to , well, like...
  13. The THINK Tank
    One reason to have fluctuation in our tanks and to not shoot for all stable parameters. I have always thought that my daily temp swing of 2-4 degrees could be helpful in helping corals survive an enviornmental stess. I had a temp spike about 2 months ago where we had a warm day and I had...

    I've been reading alot about the Phosban reactor here on TRT, and was wondering if people felt it was a good option for controlling/removing phosphate from a system? I am thinking of suckering off for one and wanted to get opinions and advice as to setup, running it, any pitfalls to watch out for?

    Fellas- I know there are no general rules for coral placement and there are lots of variables. How do you determine when a coral is in it's happiest location? How long should you leave a coral in a certain spot before you decide if it likes it there or not? Some like more flow and more light...
