toughchicken Posted September 12, 2005 Report Share Posted September 12, 2005 With Tank dividing, there are more methods than one im sure. We are currently looking at getting a larger community tank 4ft, and wish to divide the existing 3ft for separating male & female guppies. And this leads to our existing Ehiem canister filter, that we wish to modify to work for the division. My feeling is it probably wont work, but theres no harm in asking. The plan would be to have two intakes with two 6mm tubes (internal dia.) leading to a 'Y' junction on to a 12mm tube (internal dia.) to the canister, with another 12mm out flow tube to a 'Y' junction attached to two 6mm tubes ending at two 1/2 size spray bars. We are assuming an over flow allowance will have to be provided above the central divider so that both tanks would stay even in water level. intake-----------6mm-----------\---------------------- /---6mm------spray bar ------------------------------------ |------2222---------| -------------------------- intake-----------6mm-----------/-----------------------\---6mm------spray bar Will it work???? :lol: :lol: :lol: Quote Link to comment Share on other sites More sharing options...
Wok Posted September 12, 2005 Report Share Posted September 12, 2005 provided that your divider is lower than the sides of the tank I think it would work. what you could do then is to have the spraybar saddle the divider so that you can get a relative even discharge of water... and if heaven forbids if one end gets more water than the other you won't have a problem with it overflowing the sides with regards to intake it should work with taking even amounts of water out from both sides.

madcookie Posted September 12, 2005 Report Share Posted September 12, 2005 Pretty risky business toughchicken - Am assuming you are planning on treating the two halves (of the three foot tank) as seperate systems. Theres a real chance one tank will overflow and one will drain out using that system. Beter bet is to have either a hole in the divider (covered with a mesh to stop fish/debris), or a small gap at the bottom and use larger sized substrate/gravel. Then simply have input on one end/tank and output at the other. Quote Link to comment Share on other sites More sharing options...
toughchicken Posted September 12, 2005 Author Report Share Posted September 12, 2005 Theres a real chance one tank will overflow and one will drain out using that system. I see your point. the glass divider would have to be lower than the height of the tank by an inch or so, which would allow over flow from one to the next. We may need to have the ability to restrict flow manually (by tap) if the variations where too major. I personally feel that there could be too many variations, and if manual controls are used it may over work the filter. Thanks for your input!

madcookie Posted September 12, 2005 Report Share Posted September 12, 2005 Yeah, and if the divider is too low, the fish will (easily) swap tanks... If you use a tap to restrict input, thats just another part of the line that can attract blockage. All it takes is one decent sized leaf (or fish, or 'gunk') to slightly block the intake, and an imbalance will occur. Again, intake in one tank, output in hte other, with a mesh-covered-hole in the partition is the best way to go, that I know of at least... Good luck!

suphew Posted September 12, 2005 Report Share Posted September 12, 2005 Why not put an under gravel filter plate right across the bottom of the tank and sit the divider on top of this? as long as your gravel isn't too thick the water should flow between the two with no problems.

Alan Posted September 12, 2005 Report Share Posted September 12, 2005 Make a N shape from three pieces of PVC piping with two right angles and fill with water and drape over the centre partition. The water level will stay the same on both sides. You may have to cover the ends to stop the fish doing a short cut. You wont even have to glue the pipes together.
