I have a 29 gallon tall with 2 HOB
filters. I've had it this way for maybe 5 months now. I came home last night and found that I had lost a lot of water so I topped it off. Now I wake up 8 hours later and I have to top it off again? What could this possibly be?
Sometimes the filter basket it one of my HOB
's raises up a little and I get a drip down the back but I've never seen it lose water before at this rate
Any help would be appreciated
