Is there a commercially available auto water changing system? If so, which would you recommend, how well does it work?
Lol.Search the forums for posts by 'jayinh'. Think he has a system he builds/sells for AWC. If I can find the thread I'll repost.
Edit to add: Or... he can post it himself seconds before I do.
I built these and use it without issue.http://www.bostonreefers.org/forums...ater-change-build&highlight=auto+water+change
