I'm bigtime confused by this....right now cutting back the light (further) on my anubias and java ferns, liquid fertz 2x weekly, and increasing co2...also removing effected leaves.... If u feel phosguard would be preventative following this...I'll go for it big time....just a bit confused right now....other types of algae are not present in my tank either.... Thank you again in advance!!!
There is nothing wrong with algae, it is a natural part of keeping aquariums, though some is worse than others to have. Pictures may help identify it. Algae is a bigger part in newly established tanks, but I've never heard it's from too low of Phosphates, it's the opposite. Sometimes phosphates won't read on a test kit, because the algae is consuming it, faster than it can be measured, that is why some don't bother to test for it. Algae likes phosphates, that is why you want to try to keep them low.
If I were you, I'd cut my lights back to 7 hours a day. I would buy 3-5 otos (common name) or one to two Bristlenose pleco fish. Stay away from the common Pleco because they get huge (up to 24") and create a large bio load when they are big. You can also try putting the PhosGuard in your canister, it won't hurt anything. What fert are you using? I'm only aware of keeping low tech plant tanks, but from people who know more here than me, you don't likely need the CO2, especially with the plants you mentioned, but let's see if Byron will weigh in on that :) Too much CO2 could be causing the problem.
