View Full Version : Algea scrubber idea

02-15-2016, 02:09 PM
Just finished plumbing my new frag tank to my DT. I had an idea while working on this of running an algea scrubber off of the overflow plumbing from the frag tank. I know one of the issues is if it was ever plug up from aglae growth my system would overflow well I had this idea.
This is of interest to me because I'm running out of room for any additional equipment under my DT.

Sorry for the crude drawing I'm not and artist. But it should get my idea across. if you dip down for the scrubber at my fuge then back up and over in case of it plunging up it would just drain. And plumbing down then up will help water go out the scrubber and not the drain unless absolutely necessary

Red - is drain line from frag tank
green -is algae scrubber mesh
blue - very roughly outlines my sump( again not an artist)

I would greatly appreciate everyones Input on this. thanks

Lots of different ways to do this but yours is a pretty standard setup like this:

More frequently you see it across the sump:

Notice that the screens are much higher than yours as the middle section of your sump will not be as low as you have it (unless it's the return section and even then you wouldn't want it to be very low).

If you put big open cell sponge in the baffle between chambers 2 & 3 you'll catch any of the algae before it hits your return pump.

I know some people run their scrubbers off their overflow but I figure the algae is pretty much only using the nitrate and phosphate out of the water so any water will do. As such I run my scrubber off the return using a valve so that I can control flow to it. Other people will use a dedicated pump sitting in the sump for the same reasons.

One suggestion on your sump design. Don't make your baffles go all the way to the top so if your sponge gets clogged (like mine just did) it will overflow the baffle and your'e safe.

I would also put cheato under the scrubber and let it catch the extra light. Great place for pods to hide and breed.

Fire away with any other questions. I love my scrubber and recommend them highly.

Having made a TAS, you can never really let it get clogged, unless you never monitor it. With the slit down the center for the screen material and the perpendicular slots, one might clog but the rest still keep running, if you know what I mean. Just make sure you clean it when you remove your algae every week.
