Sump question! Please advice...

[Slayer213]

Hi all, i have a 2 ft mix tank thats been running for a year now using a eheim canister... I decided to ditch the canister and setup a sump to increase water volume and also a space for a proper skimmer. The problem is my tank is just a normal tank without an overflow, and i dun have space at back if the tank to add a overflow box. Ok, can i just siphon the water directly off the dt to the sump tank below and have a pump to pump the water back to the qt? I intend to place the siphon hose just near the surface of the water in case anything happen it will just stop siphoning and prevent a flood. Will it work?? Please advice... Thanks

siphon will break, and your tank will overflow, better to get a proper skimz overflow box and pair it with a aqualifter to be safe

Or get a hole drilled and get the internal overflow pipe from gemsurfs

A proper pvc pipe overflow would be a good option. Since yours is a 2 feet tank, a small diameter pvc pipe overflow should be sufficient. As mentioned, you are now using canister, the small space behind your tank for the canister hoses should be able to accommodate the pve pipes for the overflow.

risky.. look into doing a diy overflow.. i'm trying it out as well

get a vacuum pump and tap to your overflow pipe

is very risky without it, when power outage and power back on, the siphon will lost coz air inside the return pipe and stop the overflow of water to your sump.

flooded my floor few times coz of such problem

[zonerx]

the vacuum pump/dosing pump & a check valve can solve the siphon problem

total cost around 20 bucks or less only
