Phoshate Reactors

[tent boy]

I have been using GFO passively in sump. Its not really keeping up. Will a reactor do alot better job of removing the phosphate than the passive method?

IME yes.

I've personally run GFO both ways.
It's easy to make a DIY reactor if you don't want to spend $ on one but the TLF reactor is fairly inexpensive and very useful.
