Alright so I just threw the algae out. So I'm still battling this hair algae. My flow is now created by the following:
Mag Drive 7 Return from Sump
Eshopps Overflow box
3 Koralia 2 powerheads
1 Aquaclear 301 cheap powerhead
Now, it still seems that there are certain areas in the tank that are collecting detritus like certain parts of the rocks and certain sand areas. I think I just may have too much live rock that I am not getting good enough flow, so tonight I took out a couple pieces scrubbed off the algae and detrius, put 2 back in the tank, put the other small pieces in the sump (so they are out of the way yet will still benifit the aquarium) and 2 pieces I am just going to toss, or throw outside because all they did was sit under other rocks not really supporting them and they are ugly and don't help the flow situation.
Now when I purchased the rock from a local guy he gave me all he had because he was breaking down his tank, it was over 100 lbs. meaning 2+ lbs. per gallon. Here's the rock when I first got it:
Now I had an intial cycle and was fighting GHA for a while but finally got it almost gone recently when it looked like this:
Keep in mind, here I only had 1 Koralia 2 powerhead, the aquaclear one, and the sump return and overflow. However, I decided to move a couple of rocks around. A couple weeks after this I noticed GHA beginning to form again. I got another Koralia 2 for Christmas, then I went on vacation and had my mom watch the tank for me. When I got back, the left side which had the new powerhead was not that bad, but the right side was. Now I got another Koralia 2 for the right side, but it still seems as areas are not getting swept free of detrius. Again, leading me to believe I have too much live rock. What do you think?
However this confuses me, because I see all these pristene reef tanks with live rock stacked all on top just like mine and yet I only see like 3 or 4 powerheads but they have not problems.
Examples:
I do water changes, I test the water weekly. Now it is true I haven't given this time since the new koralia powerheads but I want to find out if I have too much rock and what I should do if I need to fix it, especially since I notice, not matter how many water changes I do, this isn't going to fix the collection of detrius, only proper flow can do that. I guess the real problem is that I'm having troubling achieving that flow and I'm not sure why, or how to properly achieve it.
I'll have to take some pictures tomorrow when the lights are on, and maybe I can even use my underwater camera housing to show you inside the tank and stuff. I want to know if I need more powerheads or what...
If anyone has some insight please let me know. I plan on getting new lights and hard corals in the near future and I would like to tackle this problem. I should add that I use RO/DI water.
