First to adress the brain coral we'd need additional info....specifics on water tests(ammonia/nitrite/nitrate/calcium/alkalinity/ph)...also info on your system in general...how long has it been set-up? Type of filtration?Type and amount of lighting? Live rock and how much...any additives used...do you or have you fed your brain coral...the more info you provide the better folks will be able to help.
Also I'm moving this thread over to the reef forum where folks may be better suited to respond.
Also I'd like to welcome you to the board!!
Last....we should all be aware that direct links to competing BB's are not allowed...we do have the ability to post links that are informative in nature and that provide resources not found via our host...there was a time when NO links were allowed and I'd hate to see that policy return...so please refrain from direct links to BB's.....
