Thanks for the reply @glennf
. So this is your first and only saltwater tank then. Were you successful from the very beginning or did you suffer losses when you started to keep SPS?
The reason I ask is that when I started my current tank, I tried to buy the best equipment I could afford at the time, Deltec skimmer, Vertex lights (although these did not turn out to be worth the money I paid for them but that's another story) etc.
I waited patiently for my tank to cycle and stocked it slowly, keeping a close eye on parameters.
However, I just cannot seem to keep SPS or even LPS corals for any length of time.
I had Acan frags and they just seemed to shrink and fade away.
I had a red bubble tip anemone and it seemed fine for a good few weeks but then moved to the underside of the rocks and slowly began to shrink away until it disappeared completely! I tried the plating montepora, I tried SPS acropora etc but they all faded away or went white.
I now wonder if my dodgy Vertex Illumina has ever been right. In any case, I could never figure out whether the lights were to bright or not bright enough.
I have never seemed to have a reading for nitrates or phosphates whichever test kits I used. But surely I must have had them as I have suffered algae blooms etc
I have used Red Sea Coral Pro salt from the very beginning and also made my own RODI water with 0 TDS.
At the moment my tank has been stable for quite some time and the fish are thriving, but the only corals I have at present are the Florida Rics, a non photosynthetic chilli coral, and a couple of Zoa colonies....oh and a shed load of bush coral that is spreading like wild fire!
