Sorry to be a PITA, but....

I'm assuming your main tank is a 55?

From what I've read here the size of the overflow boxes is matched to the pump (which yours is rated for 692 GPH). What sizes are your boxes?

Again with the bio-balls container; from what I've read, the bioballs should not be submerged. The container sitting on something to raise it up, giving a lot more sump water?

How did you attach the boxes to the plexi tank bracket; silicon?

Again sorry to be a PITA, but this has got me thinking hard; which is dangerous!

:eek:

what i didnt expect was the water pressure pushes down the water level in the jug past the bio balls - they stay out of the water ! The dividers wher held in place by aquarium safe silicon (lfs $13). the boxes are 6x8x3 but i cut them down to about 5-6 inches tall. maintank is 55gal. by the way youre not being a pita !!! lol
 
Same here, but was leery of being a PITA for pointing that out....

:)
 
In the future, you can get a tube of aquarium safe silicone at any hardware store:) GE type 1 without mildew resistor is aquarium and food contact surface safe. It saves you a bunch of money

Thanks!

So is this something you run all the time? I am guessin it would be difficult to rig something that would just turn on for a brief time after the power comes on, or is it? I've often wondered if there was an easy way to suck the air out of an overflow to prime it automatically, but my first overflow and sump tank will be using built in overflows in the main tank so I dont have to worry about it. But I am also thinking about making a HOB overflow similar to yours on another tank. I have seen some plans on how to make the whole HOB overflow out of 3 pieces of acrylic and thought about trying that method. But yours looks pretty easy to do.

Rallysman... have a headache? lol
 
the aqualifter sucks the trapped air out of the top of the U . if the U gets too much air in it -it will lose syphon. the pump will then pump all of the water out of the sump and spill out of your main tank , you shoud run it all of the time in case of a power outage. it was easy , the hardest part was tweeking it . i used a 5 gal bucket and a small tank to find the right level between the inner and outer boxes.
