Yes, you read the topic right.

It seems like my shrimp love grazing on this stuff. Baby shrimp will completely clean off two entire panes on a 10 gallon tank in two days!

So my question is...how do I cultivate GSA/GDA on the few extra panes of glass?

I was just planning to somehow hold them standing up in a 10 gallon tank, fill with water, throw in a few plant clippings, and blast the panes with light.

Would this work? I know GDA has a lifecycle that eventually dies out but that's not what I want. I just read a post from Tom Barr stating that despite trying, he couldn't successfully inoculate tanks with the stuff.

gda - too much light
gsa - add ferts but no po4

I think gda might out compete the gsa though.

Might want to add some ammonia too.

Better yet instead of ammonia just throw in a pleco and feed lots of cucumbers, that will add some nice organic ammonia. And the pleco will disturb the gda, which should interfere the "lifecycle".

Sounds good, you might want to add some diy co2 as well, algae loves it just as much as plants. And look at the tags below crazyepicfish lol.

By far the best way to cultivate GDA and GSA is to invite one of us experts at growing it to work on your tanks a few times a week. We have the golden touch! I would volunteer, but I now devote myself to growing BBA, and have become a real expert at that.

This is much easier than you are making it out to be.

Jobes stick, a small tank, jug etc, something with a wide mouth to add rocks, wood etc + a small powerhead. Place in south facing window

Allow plenty of aeration, add rock/wood etc, wait.

That's all.

Regards,
Tom Barr

I now have 6 plates of glass caked with the stuff.

Tank, throw in EI ferts, plant clippings, 70W MH light for 12 hours a day.
