Am i doing water change properly?

How much flow do you have in your tank from powerheads?

You can scrub first, let it settle, then gravel vac 5g of water out of the sand for your wc. That'll remove a lot of it.

good tip, the return from sump, prob 300, a 750 head and a850 head, and a 450 head that i added a few weeks ago

That sounds like plenty.
I'd just be anal about catching as many pieces of algae as possible. Anything you leave in there is just going to release those nutrients into the water for the next round, like compost.
It's a pita but the best thing really is pulling it with your fingers and dipping them in a little cup of water by the tank. Pluck, dip, pluck, dip, die of boredom
Maybe a few more snails too, the kind that eat algae- not nassarius.

Sounds like your disturbing the tank too much, just use a Powerheads in hand and blow off rocks. Try to keep it aimed away from the sand to avoid a snowstorm which could also effect parameters. Good luck. Throw some gfo in your filter sock and I hope you've been using RO water

If possible remove some rock and scrub them with peroxide. Or vinegar and a toothbrush. If you cannot remove any of the rock I still hunk trying to manually remove it is the best way. If not an option the. When you stir up the tank, maybe turn the pumps off to suspend everything in the water column and use a net to swoop as much as possible.
