That is what happened to me 10 years ago. I got the BGA gone and bam - green water. That time the tank needed nitrate to come out of it but since then it has been due to disturbing the tank cycle more than anything else I think. You can sit back and squint so as to not see BBA, GSA and all the rest but GW is sort of obvious.
Well thinking on the flat tank syndrome issue doesn't cost anything. Maybe you could go beach/lake/river combing and get lucky or find some long twisty sticks and put them together.
