Hey all, so I have a planted tank and had a massive outbreak of algae growth all over the glass, driftwood, and plants so after researching and reading around here I found out what my problem was: I recently purchased a LED grow light that is meant for greenhouses for my tank trying to upgrade the previous light fixture for better plant growth. But what I did not know was that it uses blue spectrum lighting which apparently encourages alage growth, causing this outbreak all over my tank. Now my question is, is there a way to control the alage without having to get a new light fixture? I like the lights as I have had AMAZING plant growth while using it (I propogated some rotala and they grew almost 2-4 inches in a couple days!! Pretty soon I'll have to trim them again lol). I do use injected co2, and also dose with plant food/supplements. My lights are also on a timer which keeps them on for around 12 hours a day. I also have tons of ghost shrimp in the tank but I doubt they can keep up with the algae growth since they also have plenty of dead plant matter to eat. ( They probably are in heaven right now with the feast they have to eat xD) I have read that increasing the co2 dosing could help control the outbreak by increasing it to just under the point the fish would start suffocating but since I don't measure co2 and I keep the system always on at a rate of about 1 bubble every 2-4s I'm afraid that I would wake up to all my fish bottoms up x.x I have also thought about getting an algae eater but with my current stock I only have enough room for 2-3 more fish max. ( 20g Long) Also since the algae eaters are bottom dwelling they would not eat the algae off the glass right? Also worried the shrimp or the algae eater might bother one another. Thanks for reading and taking the time to comment!
