i tried to do a refuge outside my tank but it wasent working and turned it into a sump any one have any opoions about in tank refugiums

[Tangster]

How did you try it outside with a HOB unit ? Or do you use a sump ?

[kFAMOUSK]

i had to use suction for the over flow box to go down into a tank then a float switch to turn on and off the rio 700 to send it back to the tank

thats risky

how do u get the water to go into the over flow box and down the pvc without suction......

[Tangster]

Yes it risky alright the way we build them is they have a hanging lip and I make then 5 in wide and 12 in deep and lenght to suit the customer and a Little pump on the out let to the tank and a siphon U on the inlet and its baffles to hold the sand and plant section safe.
