DIY automatic water changer
I'm looking to build an automatic water changing system for my 55 gallon
discus/plant tank. I am planning on getting a larger 6'x2'x2' tank soon and
I would like to be able to re-use some of the components.
My current tank has a canister filter and an Aquaclear 200. What I am
thinking of doing is building a wet/dry filter with a sump. This means I
will finally be able to put my CO2 reactor out of sight. I plan to purchase
two overflow boxes - one for the tank and one for the sump. The idea is that
I can pump fresh water into the tank and as the sump water level rises due
to the extra water the sump will overflow into the drain through the second
I will have a timed solenoid valve on the input tap water lines which will
be preset to the correct temperature using ball valves. Since my water has
chloramine I plan on slowly passing this water through a large carbon filter
before allowing it to enter the tank. I plan on adding water probably twice
Has anyone set up an automatic system like this? I have seen a few of the
ones mentioned on this list but none of them seem to work exactly this way.
I have never had a trickle filter before so if something obvious is wrong
with this scenario please let me know.
