I have a new type of algae! Woo hoo. I have gone through all kinds of algae with this tank. Diatom,hair, green spot?(Currently have this too). One day I will find the proper balance. I am pretty sure that my lighting is too high while the fertz and or diy co2 are too low. I am ordering a dry fert mix next week and hope to have all the stuff for a paint ball co2 system by the end of november. One day I will find balance. Any way, sorry to ramble! Can some one I'd this algae? Also if/when I get a good balance going will the green algae die off? I've tried scraping it off the leaves but it won't budge. I'v had the same problem with this new algae. Thanks in advance.
