After testing my water today and finding out that I've managed to get all of my parameters to perfect levels aside from my phosphate I figured now is the time to see what the best option is to get rid of it.
Since I set the tank up in april I've had a continuous .25 level of phosphate despite some amazingly well growing grape caulerpa and some slower growing chaeto.
I was considering using something like phosban and putting it in a HOB
filter. Would I be wasting my time with this or could it work? Is there a better / similarly affordable option?
