Back again, Keep having issues can’t keep nitrates up

I have a 32 AIO tank for a few years now , I’m having issues keeping my corals happy and some of my hammer heads are dead and every parameters I have been testing are where they should be. I just don’t know what to do anymore

Anyone selling frags around celebration FL?

Any ideas for a ATO reservoir that’s not to expensive

Hello! Is anyone dealing with micro bubbles or particles in their water? I'm wondering if it could be coming from the return pump. Any insights or experiences would be greatly appreciated. See video below for reference.
