so I have a tank that's about 1 1/2 years old... Phosphates have ALWAYS been an issue for me... I've tried everything I can but at this point I'm just gonna throw in the towel on controlling it... I have a 25 IM lagoon that I bought used with the rocks pictured.. I can't seem to get it down past .5... I sue instant ocean reef crystals... I feed tdo in the morning and ROE in the evening.. I try not to be heavy handed with feeding... I generally do a 20% water change every tow weeks which helps for awhile... So i'm thinking the only thing I can do at this point is to slowly replace the rock and try to get as many zoa's as I can on the new rock... thoughts???
thanks....
thanks....
