Thanks! I just recently identified it as BGA. I thought it was diatom. I have successfully get rid it before by turning down the light intensity. My lighting doesn't support dimming but I have two short led light for left & right. I just turn off one for a couple of days. BGA turn grey & die. I have repositioned my lights so that they are positioned higher. Now we'll see if this helps.

The root cause most likely is the soil. I use too much organic soil about 1 inch but inadequate cap (1 inch too). I'm trying to get away from re-scaping my tank.

BTW, do you have any idea what toxic kill fish but not shrimp? I'm trying to put a bristlenose pleco but it died while my ghost shrimps (riceland prawn) have no problem.

BGA is easy to kill but it tend to come back. I believe it is because the soil because the same soil use in the garden also grow a little bit of BGA on the soil. I have since two months ago, rescape my Tank #2, clean all of the gravel & added fine sand to get depth to slightly more than 3 inch. So far there is no more BGA. All plants doing well. So far only three types of plants in there that survived.

Problem with Tank #1, BBA appeared on the edge of old leaves. Dosing micro & macro to get the plants healthy. So far all plants are recovering with healthy new leaves but it is slow progress because no CO2 injection & this is not dirt setup.
