Well, on the advice of the ATS expert, SantaMonica, I've decided to re-design my ATS.

I have two plastic screens superglued to a large 11X12 piece of egg crate. I'm going to get a new piece of...

Well, I didn't mean to ask where to put the GAC bag, but whether I'd still need that. We discusssed that maybe I should take out the GFO phosphate reducer (currenly in a mesh bag) after it has run...

Okay, SantaMonica, thanks for the help. I wondered about the size of the bulbs. I thought using the snail to clean would get the junk out, but I guess when they poop, they put the nutrients back...

I have an HOB overflow box with two exit pipes. I designed an ATS so that the water exits the HOB overflow box from the two pipes, down to the single pipe holding the screens of the ATS, then out of...

I have a retangular trashcan bucket for the holder on my PVC pipe. The distance from the screen to the edge of the trashcan is about 3-4 inches. I bought clamp on floodlight lightbulb fixtures for...

You mention leaving some algae on the screen to seed the next week's batch, but no one says how much. SantaMonica recommends 90-95%. Someone on Rc said keep one side and clean the other.

The...

Rumpy Pumpy,
I usually turn off the skimmer and return pump while I'm feeding for at least 30-45 minutes so the livestock gets the majority of the food. After that, I want the filter to pull out...

Can I remove the Chemi-pure, GFO, Algone and filter sock all at the same time?

Doesn't the filter sock help pull out the big chunks?

Why do you recommend not to use any filter socks? Don't I need to get the BIG chunks out before the water goes to the skimmer to ease the workload on the skimmer?

Okay, so I set up my ATS and put it "in commission" about 17 days ago for my 120 gallon Display Tank and 25 gallon sump. I have a double-sided vertical screen with eggcrate between the two screens...

I run the aquarium water from the Over-The-Shoulder Overflow Box to the ATS to the input of the Wet-Dry Filter. Because of the specifics of my wastebasket-shaped ATS and the height of the input of...

I was thinking that I would cut through a single piece of plastic canvas with the hole saw and I wanted something more rigid to hold the screen in place, so that's why I used the eggcrate.

So if I...

I used a piece of eggcrate and glued two flimsy pieces of plastic canvas to it. SantaMonica said one screen and no eggcrate is best. Now the lower hole in the main pipe where the water drips onto...

I found two 23 watt spiral CFL bulbs. Now, I'm looking for 2 jelly jar lamp holders so I can lower the bulbs into the bucket to better cover the screen with light.

My newly installed ATS has about an inch to 1.5 inches of water in the bottom of the plastic bucket (trashcan) below the bottom of the outlet bulkhead, because I didn't drop the screen down low...

I just designed a new ATS using the "bucket format design" mentioned here. The screen is 11 X 10 inches for a display tank of 120 gallons and a sump of 20 gallons and sits vertically with roughed-up...
