Re: Automatic water change system design DIY Zab - I'd love to see some pictures of your setup if you have them.
Also, as for the air bubble problem in the drainage loop, I solved this by drilling a small hole at the top of the drainage loop where the gas gets trapped and running a 1/4" tube to an aquilifter pump. The pump sucks out the air and keeps water in the top of the loop. It works very well. I'll see if I can take a picture of it soon. |
