Its back to basics, what is your water source, what additives are you using, do you have a skimmer, have you started using rowaphos yet? Remove as much as possible by hand, I wont do water changes as it just fuels it more (up to you) my theory is let it drain the nutrients by it self, when it slows down start the attack, alc up to 12 or 13 dkh, mag at 12 to 1300, rowaphos both tank and topoff water, when it starts to go clear or white I use a 3/8 id tubing with a length of 3/8 od rigid air line tubing a bucket with filterfloss and start to siphon it out, put your finger over the rigid tubing while draining allow the HA to go into the pipe, trap it with your finger and pull, its a WAR! take no prisoners lol
