Still a problem!

[Yellow Eye Tang]

Wow,.. I was just sitting here researching this. I am just having a **** of a time with my 20g planted tank. I have 64watts floresent running on my tank and I just cant stop the hair algae growth. My lighting is now down to 5 hours (for three days now) and im treating with florish excel (which everyone says will take care of the hair algae). I'm afraid of overdosing it but something has GOT to happen here. I'm afraid of going blackout because I think when I come back on it will just restart itself again. I'm going in now to try to manually pull off as much as I can. The plants just dont seem to be growing under my light / Co2 situation even with a little excel and API's leaf grow. They grow a bit and I notice it however, they obviously are not starving out the Hair algae. The leaf grow is pretty much potassium and Iron. I was going to make a comment about pulling my hair out but everyone would just think I was talking about my tank anymore. LOL Help!
