I have a 29 and 55 gallon at about the same level. The 55 is slightly higher water level, but I would be willing to put the 55 water level down to the top of the 29 water level. I'd probably lose about 7-8 gallons, but gain obviously the 29.
I want to buy a Fluval FX5, the same as I have on my 75, and have the intake in one and the output in the other, how could I connect them so the water will flow between the two? Is there a process known for doing this? Would I have to drill and fit a simple pipe between the two? Any other ideas?
I am completely unfamiliar with sumps, how gravity works (hehe), etc but I'd really like to be able to cut out the HOB
filters I use on my 55 and one of the 29s in favor of another FX5.
I have full battery backups on all my tanks to keep them running during power cuts, so I am not that worried about flooding due to that specifically, but if you do have any ideas please note the likelihood of floods if power was to be cut.
The main issue is that one of the tank contains aggressive fish which cannot be mixed with the contents of the other one.
The water parameters are always shared between my tanks anyway as I use the same type of wood, plants, etc in most of them. So I guess I'd just need a straining material over the piping.
