I have no idea what this is ?

My hammer has been slowly browning and I found this on the side of today , any idea of what it could be ? Sal-1.024, ph- 8.2 , cal-360 , alk-8 , Phosphate-0 , nitrate 5

Pineapple sponge.

Harmless filter feeder. Will multiply in immense numbers in any dark place and then starve to death.

Looks like a pineapple sponge - harmless filter feeder and not the cause of your browning hammer.

Browning??? Maybe I'm missing something, but that hammer looks very pale to me.

Your nutrients are way too low for this type of coral.

Leave this sponge. It will vanish on its own. Silicates are often cause. Can be from new rock, new sand, from tap water if used and expired or leaking Di Resin cartridges. These are short lived and will dissipate as silicates reduce. You can peel them off with the edge of a credit card into a net if they are too many.
They are not harmful and cherish algae if they get any

Ive been raising my nutrients with feedings , just don't want to over do it . What would you say they should be at ?
