Issue with hair/thread algae, too much lighting?


I'm sure it's not just one factor, but I keep having a slight build up of a stringy algae in the fore ground on the gravel of my tank. It pretty much engulfed my HC, and I've since been trying to completely clear the area of hair algae before resuming failing at HC..

My parameters are:

- 10 Gallon
- Eco Complete
- Fluval C02 Mini
- Rootmedic Complete 500 (2x a week)
- Occasionally adding Flourish Excel
- Floor lamp with 26 watt 6,500K CFL
- Photoperiod: 3 hours from 8-11am then 4.5 hours from 7-11:30pm

I previously was running a 32 watt CFL, but figured reducing my wattage to 26 would help clear this up. Also have stepped up my water changes..

Should I Possibly decrease the wattage on my CFL further or should I keep with what I'm doing and maintain more frequent water changes? It seems like spots in the tank not in direct light don't have the algae issue... Thanks for any responses to my novel ^^!

I had some stringy stuff showing up when I added CO2 and traces (Fluorish), but before my other ferts had shown up. Once I added the other EI ferts the stringy algae vanished on its own in less than two days. Occasionally I get some right around my airstone when I'm running it, but it vanishes as soon as I move the airstone.

Interesting, anyone else have an opinion about my amount of lighting? Too much, too little, just right?

I'm not the resident lighting expert by any means, but how is it positioned? Someone around here (probably Hoppy) put a PAR meter under lights at different distances and orientations. The distance and orientation had as much to do with the PAR readings as the rated output of the bulb with the CFLs.

Adding say 10-15 Amano shrimp, good CO2 and a good trim likely will solve most of this.
