Aquarium Advice FINatic
I'm working on my new 20 gallon long. I've got a pretty good case of thread/hair algae. This stuff is long!! I think I've attributed most of the problem to too much light. I've got 130 watts over the tank total... my new plan is to have the lights on 10 hours a day, with a 4 hour 'peak' period where both ballasts are on, while the rest of the time I've just got one going. I need to add another diy co2 2L (I know... I'll need a lot more with all that light, but this was a challenge, I want to play with it). I'm also still tweaking my fertilizer routine. This tank has only been up a little over a month. My stem plants have probably saved this from being a complete algae infestation. At the current rate I pull a bunch of thread algae out every other day or so. The algae started when I started using both 65 watt fixtures. Here's my question: will a three day blackout help knock this stuff back a bit? I've used such a black out with other types of algae, never anything like this. Any thoughts?
