What am I missing?

PH-8.3
Ammonia-0
Nitrite-0
Nitrate=0-5.0
Cal.- 425
Phos- 0-5.0
KH-8-9
Mag-1350
Tank is FOWLR, 2years old
Problem is milky water. Cannot clear it up, going on now for 6 weeks. Have done water changes, 50% and 15%, water will clear for a couple of days and will go right back to milk. Nothing dead in tank.Careful about over feeding. The only thing new is have been feeding corals with reefroids, started with 1 tsp and now back to 1/2 tsp twice a week. What am I missing?

Is Phosphate 5.0? Or do you mean 0.05? You definitely need to get that down if it's 5.0.

Cloudy water is bacteria. Are you carbon dosing? Do you have any fish that stir up the substrate like a gobi? Both of these will cause cloudy water, although eventually the cloudy water caused by a gobi goes away after the substrate clears up.

1tsp is a lot of reef roids unless you have a lot of corals.
What kind of filtration are you using? Skimmer? Canister?

Phosphate is 0.05. I cut back to 1/2 tsp of Roids 2 times a week. Use a sock filter and a skimmer. I believe I will stop feeding roids because I didn;t have the problem before and then start back with smaller dose.

I did notice my Yellow Tail Damsell stirring up a column of silt and eating something from the column but that would clear up.
