Coral/water chemistry question. My tank has been cycled with Dr Timms, I have 4 small damsel fish, a couple of clowns, CUC and some small coral frags - the fish are fine, but the corals aren't doing too well. The 2 Zoa's are fine, both open quite happily, however the Montipora isn't looking so good - going white at the edges and losing some of its color, the green star polyp opened the first couple of days and has been shut since and the pulse polyp the same. If I've done my research right these should all be fairly hardy beginners corals?!
Lights are a pair of AI 26's set to ramp up/down for an hour morning and evening and then lights on for 11 hours, everything set to 60% apart from green and red which are off.
Water readings are:
Salinity between 1025 and 1026
Nitrate 10 (that needs to come down I know - algae reactor will be up and running tomorrow which will hopefully sort that pretty quickly)
Are Ca and Mg too high?
Soft corals have been in for about a fortnight, SPS for just under a week.
Any suggestions appreciated....
