Hi all, I have a 60g Fowlr that's been running for about 2 Mos. I have 55lbs of live rock, a fluval 406 canister, 2 clowns, 1 purple basslet, 1 blood shrimp, 3 Turbo snails, 2 peppermint shrimp and 3 blue legged crabs. I'm seeing some purple algae and wondering if I should be concerned

What's your nutrient levels?

Nitrates 20
Nitrite 0
Alkaline 180
PH 8
Ammonia 0

I don't have anything to measure phosphate. Will it harm the fish?

It would have to be crazy high to do any harm. What means are you using for nutrient export?

Did a 10% Water change 10 days ago. Picked up a skimmer this afternoon to supplement but wasn't putting it in until Monday.
