Re: Water Changes
I have an automatic water change system. When I installed my tank I cut a
hole in my oak floor, this was a leap of faith, and bought a 75 with three
holes drilled, a pump drain, return and a system drain that goes to the set
tub sink in the basement. I have a peristaltic pump in the basement and a
reservoir in the form of a 30 tall that the peristaltic pumps from. This
replenishes the tank at a rate greater than evaporation, has liquid
fertilizer mixed into it, and has some crushed coral in it to PH buffer it.
The system drain was modified to skim the surface. I would estimate that
the peristaltic pump adds about 1-2 gallons per day above evaporation rate.
I also like this system because the co2 is fed into the pump (a supreme 600
I believe) and the co2 is effectually atomized into very small bubbles. The
tank used to have quite a surface scum, which is now washed out of the
system on a constant basis taking with it what dissolved organic carbons
would have broken down. I believe personally that a lot of these are
allopathic chemicals captured by the 'skimmer' effect of the co2 bubbles.
