I'd really like to get a drip system going, but can't run piping to and from the sink at my townhouse. I have a 125 gallon tank and would like to be able to do 25% once or twice a week depending on what's needed. I have a flo pure and I was thinking of filling a 30 gallon bin and have it feed into the sump. The bin can be refilled when needed. I'd then have another 30 gallon bin that would be used for waste water. I'd either remove and empty the bin or throw a small pump on it. I have a sliding door next to the tank, so I can always take a hose from the pump out the door to empty the bin. If this would work I'd still have to figure how to tie everything in together. Any ideas and feedback would be greatly appreciated.
