I recently set up an algae turf scrubber. Just wondering if anyone else is running one. How do you like it?
I thought you were asking about an Automatic Transfer Switch (for a generator)... lol. But, since I'm here I'll throw my 2 cents in.
I've heard a few people around here have experimented with scrubbers and from what I've read they do work but only about as well as chaeto does. Therefore, most will just throw a ball of chaeto in the sump and trim it every now and then without having to setup the whole scrubber contraption.
If you have a basement and/or fish room where you have the room for an elaborate system and can hide it from the wife/girlfriend... it can be very effective. I've even heard of some people just using a shallow trough on the drain to the sump (with a very slight slope to allow a slow flow) with some lighting to inhibit algae growth... which is both out of site and out of the display. This is easy to clean as you can just swipe it out every week or so.
Like I said though, it's much simpler to just put some macro algae in the sump than to come up with a design for an algae turf scrubber.
