Help Phosphates to high.

[takeastabatit22]

So I'm learning about phosphate spike. I have done 2 20g water changes this week on my 80g tank.my Hanna checker still is reading over 200 ppb. Ive dimed my radion light to 33% to aclumate a batch of new sps.

I'm looking to add a reactor or 2 for gfo.

Any tips or is their any difference between name brands?

I have bought 2 1.5 vertex thought they are missing the same parts and I can't replace them without going to vertex.
Do the cheaper versions work just as well? Like 2 little fish?
