If you are planning to set up a drip to drain system please note the following.
Your incoming water should be as far away from your out going water drain line.
If your water contains chloramine it will make the main purpose for using a drip to drain system useless. Chloramine, unlike Chlorine is not easily broken down by carbon and will not dissipate through air-ration. As a result if you try to stickily use your drip to drain system to do water changes, over time the Cloramine will lead to a nitrate crash killing all you fish over night. What I do to get around this problem is to remove the amount of water I need to change by a pump first. Then add Aqua Science Ultimate Water Conditioner (or something similar) before adding fresh water. Fresh water can then be added through the drip system. Try to get you tank drips set so that the amount of water need to refill the tanks fills them all in about the same time. Once the tanks are full turn off the fresh water. Your overflow will handle a overrun; but, try to limit over runs as much as possible.
There is a filter system that also can remove Chloramine on the market. However, the slow amount of drip needed to use this system makes it hard to manage for any larger fish room. Fir me to use the filter type system I would need a huge water reserve to hold water dripped from multiple lines through separate filters. Not only is the water storage an issue; but, I then need also would need a pump to move the fresh water through your system. In addition the cost for replacement filters is likely to be more than using Ultimate Water Conditioner purchased in bulk from JEHMCO.
