Okay, there's a million posts and youtube videos on this topic but I'm at a loss here. Feels like I've read them all, watched them all and tried almost everything. Nothing is working.
Here's my set up. 120-140L system with sump, Hydra 26 light on for 6 hours, 3 clowns, royaldotty and a yellow fin damsel. All happy and 3 years old. A mix of soft and LPS coral. I do a 10L weekly water change, always Fri/Sat and add Vibrant etc after. I'm using RODI filtered water.
I've tried 4ml of Vibrant weekly.
ROWA phos in a bag in sump
Aqua Forrest Phosphate minus in reactor (100g replaced every so often)
2ml of Hydrogen peroxide daily for a week
Lights out for 3-4 days

I recently got new filter socks, took a while to come from China. Was using an old one which was just holding together. Put a new one on, left it for a week and it's still very clean.
My questions really are
- What mostly causes it? (Nitrates, Nitrites, Phosphate or light?)
- How can I tell which one is the issue, all my tests come up normal levels (but likely because the GHA is using it up therefore not showing on tests)
- Is Aqua Forrest Phosphate Minus or ROWA Phos better to use to remove phosphate in a reactor
- What's the most recommended method? (it's mostly short to hard to remove by hand)
- Aqua Forest - how much should I use and how often should I replace if I do this?
