Green tufts that are near impossible to remove!

[Floyd-]

I have had these little green hair balls on the rocks for some time. They are near impossible to pick off and now this week I have a little coat of slime on it also. Any thoughts? Attached are some pictures and some water info I took last night.
I dont dose or anything. Feed frozen once a day and maybe pellets as well. Filter floss is changed maybe every 3-4 days.

Hanna test:

calcium-460
nitrite-0
phosphate-0

If possible dip the rocks that don't have any corals or sponges in 6 parts aquarium water to 1 part H2O2. This is a bit tedious but for the rocks you can't dip or remove use a syringe filled with H2O2, press the nozzle intothe ball of algae and gently squirt about half a mil into it, move the nozzle over a bit and repeat. Squirt, move, repeat . . . Total amount of H2O2 used should not exceed 1 mil per gallon and I'd wait a week after treating to retreat. Depending on how severe or resilinat it is it may take several treatments. DON"T REDUCE PHOSPHATES below .03 mg/l as this will have a negative effect on corals and they won't be able to compete with algae.

I will pick up a hanna phosphate tester. The whole "match a color" charts drive me bonkers.
If it is in fact 0 how can I bump it up some? Does everything else look ok?

I don't see anything worrisome in your photos. Feed your fish more. There's various products to bump up phosphates. Just be sure closely follow directions and to monitor it. If it helps most of the oceans are around .2 mg/l and upwelling will expose corals to that much. This paper found levels of .5 mg/l increased growth:

Turf algae. Agreed with above. You could feed heavier or dose what u need. Get some snails. They will go thru the algae like nobody’s business

Funny thing is last time I posted pictures people were telling me 2 times a day for 3 fish was too much.

I have some large snails and hermits and two emerald crabs. What sort of snails would eat this stuff and how many should I grab? This is a 45gallon setup.

Your emerald crabs eat it. Urchins and chitons eat it also.
