algea scrubber

Why would you be ashamed?

That's a great ATS! You've essentially covered all the problems with horizontals.

Your 45 degrees is steep enough that islanding will be avoided. (The little islands that force the water around them leaving dry peninsulas down stream can't happen at that angle.)

The narrow width forces deep flow which provides the same result.

No splashing or problems with water separation from the screen. This can happen easily with vertical screens and will result in splashing.

The perma-felt sounds way easier than the painful scratching -off of plastic screen. What exactly are you using?

Did you have to fiber-glass the wooden trough?

Do you have to clean any salt off the bulbs?

Thanks again for the pictures.
 
Algae has been shown to need to rest just like most everything else. 6 to 8 hours is called for by most. It is most commonly recommended that the scrubber peak light period straddle the main tank's dark period. I use 6 hours off.

When the lights are off on the main tank, activity and respiration of the inhabitants drop off and the pH will change. Running your scrubber during this time will help stabilize the pH in the main tank.

Kcress,
The filter felt I found at Dr Fosters & Smiths in the filter media. Reasonable price and seems to be handleing the scrubbing well. If I pull it loose or it just gets too funky I'll just replace it and seed the new with a hunk of the already started felt. I made it from spare lumber I had laying around. Then I coated the inside with an epoxy resin. Don't have any salt build up on the bulbs to speak off. They sit about 6-7" off the ATS surface.
 
Nice. I really like it. Thanks for the info.

And, Herring is right. Plants need a dark period. It's as Turbo said. 8/16 hrs. I suspect you will see even greater growth. You'll also save electricity and bulbs. I'd run the off hours during the day so any heating affect is minimized and present during the coolest house times.
 
I am hoping its ok to bump this thread up because 1) its a sticky, and 2) there have been some major advances in leds recently and I’m wondering how that has changed the game for those who have been using their ATS (and FATS) system?

If its not ok I’m sorry i wont do it again!!!
 
Price being a big one, but so many use them for coral and plant growing now. I don’t know the exacts for it at all but I have watched the advances and am curious on the changes if any, it’s made for these filtration systems.
