I use RO
source water that I know has no po4
I feed every two days...I only have one neon dottyback in the tank. I have a bunch of snails and hermits. I might try a crab but I am a little leary about it.
I have been manually removing it with an airhose syphon every time I do a water change. I suck it up the syphon and then pinch it off at the base and suck it out of the tank.
I forgot to mention I have been battleing it for about a year now.
I took put a peice of red coquina looking rock I have had in my tank for a long time yesterday....I think it might be leaching po4
, even though the poly filter is removing it now so the test doesnt detect it.
I have tried everything I know of...I will keep battleing it I guess!
