interesting....does this take your sump right of it? I wonder how easy it would be to change the filters in it? I'm going to look into this myself.
you should definitely look into it. you wont even need to get your hands wet to clesan the filter and it taskes only a few minutes.
You won't have to drill your tank if you make a diy overflow (plans for it found in the stickies of the diy section on mfk) for it and have it tie back into the drain. Then it's just a matter of replumbing.
With your setup we could do it with a riser pipe on one side and then rework your plumbing, no drilling will be required but the re-work on the plumbing is to much to type out at the moment.
i do have 2 over flows on this tank the only concern i really have is that my 2 sumps are attached to level out the water. i dont know if you remember this. if i use this aqua ultima does it matter that one overflow spills faster then the other. i was thinking of drilling the overflow box for my drain. am i making this more confusing then it really is?? essentially all i need to do is pipe all 3 pipes from my overflow into one and attached that to the ultima and then pipe one pipe to the pump to pump back into the tank and pipe one pipe to the drain for the backwash does that sound right??
