Hi all, I need to hear all the reasons this won't work. I wouldn't
mind if everyone said it will work just fine, but I'm sure you guys
can blow some holes in the plan.
I'm in the process of installing a 180 gallon acrylic tank in my living
room. It's used, I got it for dirt cheap and it's pre drilled with 7
holes in the bottom. Two of the holes are inside an overflow
baffle/box, the other five are open to the body of the aquarium.
Four of the five in the body of the aquarium and one in the overflow
I have plumbed to a common pvc manifold that feeds the inputs to
two XP3 canister filters. The canisters return water to the
aquarium via 2 spray bars. The last hole in the body of the
aquarium is plumbed to waste.
That leaves one 3/4" bulkhead fitting within the overflow box that
I'd like to use for auto waterchange purposes.
I plan on drip feeding new water into the aquarium (household
water supply is from a well so there are no chlorine/chloramine
problems to deal with) at a rate that will equal 100 gallons/week,
(i.e. 1 to 2 drops per second). What I am questioning is the drain
part of the system. The diagram below shows the plan I have in
mind. The backup drain point is 1/2" above the desired water level
and is only there in case the #1 drain point clogs. I plan on using a
coarse sponge over drain point #1 which I will rinse out weekly. I
dose my other aquariums using the EI method and I plan on dosing
that way with this one as well, except for the ongoing waterchange
equal to 100 gallons per week instead of the weekly 50%
waterchange that I do on the other aquariums.
Ok, the firing range is open, shoot it down before I plumb it it.
Thanks in advance for looking and for all the good advice I'm going to
