A drum for your sump would be fine. Just make sure it is clean/safe for the fish.Originally Posted by gigaguy
-advantage...it's sides would be stronger, in regards to being buried
-disadvantage....the depth...now you'll have more 'head' for the pump to deal with.
The sump needs to hold more water then the GB's combined.
Fish tank....you 'could' use a 55 gal drum. The height would seem awkward to me. Plus, now your air pump needs to be able to pump deeper
Is it the kind that has a suction side and a discharge side....like a swimming pool pump has....? Run the suction line to the bottom of the sump.Originally Posted by gigaguy
.It looks like it 'might' work. If you put a drum in the ground, plan on keeping your FT as low as possible. Keep the 'head' as short as you can.Originally Posted by gigaguy
When buying a pump, figure how much water you want to move. Figure out what the 'head'/height you need. Add a little to that for resistance of flow in the pipe. Now, you need to find a 'performance curve chart' and see if the pump will meet your needs.
Here's an example...

Also, look to see the wattage of the pump. In the long run, it would be better to spend a little more, on a more efficient pump.
If you use clear tube, and have water going through it....it will turn green. After your system gets established....all your pipe will have algae growing in them. It's best to slightly oversize the pipe .Originally Posted by gigaguy
Most people do not let the top of the gravel get wet. It 'will' start to grow algaeOriginally Posted by gigaguy
