BGA between glass and substrate

Re: BGA between glass and substrate

Insert a black plastic, or any other material, between the glass and the substrate. It blocks the light and the ciano vanishes.

 

Re: BGA between glass and substrate

I use a low tack black vinyl tape on the outside of the tank to block light for a few days. Interesting, while I see it there occasionally it does not spread.

 

Re: BGA between glass and substrate

I've had this as well. Usually, I just try to vacum it out at cleaning time. What light are we trying to block? From the aquarium lights? Doesn't the gravel do that? Or, is it light from outside the tank? Sorry for the confusion...

 

Re: BGA between glass and substrate

Ambient or light from the widows is what I block. I usually see it on the side of the tank with the most light through the windows.

 

Re: BGA between glass and substrate

I have this same type of BGA but it is only in my two tanks with Eco Complete. My tanks with Shultz Aquatic Plant Soil and Soilmaster Select (new tank) do not have it. I guess I have had it in both Eco tanks for about a year now but it is only on the glass at substrate level and has never spread. It always seems to stay just below the surface also so I have never given it much thought.

 

Re: BGA between glass and substrate

i have the same bga in most of my tanks. i take a plastic spreader and pull back the gravel from the glass,use a plastic sraper and clean.this procedure will last sometimes a couple of months. also i've watched the otto's work on it right after i pull gravel back,they seem to love this algae.if your plants are too close to glass this does not work. regards,cornhusker
