Hi…
I'm not sure where to turn with this question.

I’ve used (seaklear) lanthanum chloride to cut down on my tanks green hair algae. I continue to monitor for phosphates and drip 3ml of lanthanum chloride in 2 quarts of RO/DI water into a 10 micron sock as needed.

Now I have a question about the remnants of GHA when it subsides. How long does it take for the rock to show thru again, I have a brownish slim covering over much of the rock where it was covered with the green hair algae.

Does anyone have a solution? I’ve tried scrubbing with a brush, not much luck with that.

I’m also considering taking out the rock and replacing it with live rock, maybe from Tampa Bay Saltwater.

Any help would be greatly appreciated...
