Inverts keep dying. HELP!

[Haus]

First I tried vinegar to lower nitrates but no improvement in algae. I found I had zero phosphate with nitrates 40-50. Getting phosphate up over 0.3 nitrates have dropped to about 25 and the gha has not been growing. Before each water change I spot treat an area with hydrogen peroxide. Been a few weeks and I’m not seeing much come back and finally no long strands. Once I feel I can support the inverts I hope that cleanup crecontinues the job. It’s not beautiful but it’s steadily and slowly improving.

I’ve used brightwell neophos to bring the phosphates up. theres a formula. In My 65 I’ve used a half a cap once a week for the past two water changes. tou Need to have phosphates to lower the nitrates.

I just feel like I have tried everything. I am testing zero phosphates but the GHA is insane..... I am debating getting GFO or using phosphate remover.

You have zero phosphate and want to use gfo/po4 remover? I'm confused. Aside from that your zero po4 is part of your gha issue. I'd be removing rocks and doing manual removal and hydrogen peroxide scrub. I have a bottle of neophos you're welcome to.
