Thanks, and I hope you don't mind, but I have some additional questions. I am guessing this is intended for bare bottom tanks, but if I surround the weir with some black blasting sand, would it act like an underground filter? How far would the mineralized topsoil need to be from that suction to prevent the tank from turning black? My plan has been to run a pressurized co2 planted tank, with the plants and deep substrate providing most biological filtration. The sump is going to be filled with lots of pot scrubbers and filter pads to polish the water.It pulls water and debris up from the bottom and overflows down the stand pipe. The top slots provide some surface skimming while the majority of the water is pulled from the bottom of the tank.
The other option I have is to remake the weir, sort of. I will cut new teeth on a clean piece of acrylic sized to match the existing weir, then cut the top of the existing weir out and weld the new piece to the old weir that remains. This will add suction at the top and eliminate it from the bottom.
Does that sound crazy? I have most of the weekend to decide as I still need to buff this sucker first.
Thanks in Advance,
Todd
