coarlaine won't come back

[tdchicago]

ok, I made a bad call I think. several months ago I had red slime and I treated with erythomiacin. Not only did the red slime go away, so did all my coralline!

Since then, it has not come back. I do my water changes, paramaters are fine. The rocks have taken on a dark color and to me, do not look "clean". I up'd the cleaning crew to no avail.

I use ro/di water, and change about 20 gallons every 2 weeks. Skimmer is doing fine, and no other changes.

Did I hose this system for good with the erthymicin stuff?

red slime attacks bacteriacide not a herbicide so I can't see it killing corraline algae.

What is you alkalinity level----sometimes raising it to 11.5 will stimulate corraline algae growth.

Is this a Fowlr tank---if so you should check your calcium and magnesium levels too even if you don't have corals

What is your Calcium level Corraline loves Calcium

coralline needs high Ca. and Mg. levels to produce faster.
i keep my Alk @ 10.5
Ca @ 475
and Mg @ 3Xs the Ca level @ 1425

keeping the Mg level @ 3xs the Ca level induces coralline growth...
