KH director below tank?

[FishyFishFish]

I'm considering adding a KH director to my AIO.

It will need to go in the cabinet below the tank. Is that safe or is there a risk of siphoning?

If the rollers went bad on the dosing pump it could but you would need both the draw pump and empty chamber pump fail at the same time plus the seloniod inside. 3 years along side of my one tank no issues..

I know this is wayyyy late but OMG YOU SAVED ME

iv been looking for this answer everywhere and could not find one

So the pump has rollers that rotate in a sealed environment thus creating suction and water flow

Aka it will not allow a siphoned threw enless the rollers fail

This is exactly what I needed to know off to but an

KH director

And I guess I'll order me an ion director to but man waiting 4 months is gunna kill me lol

Yes - there is three rollers. If you have your worst bad hair day ever and only a doser pump connected - they can theoretical stop exactly in that position (we are talking in µm here) that no roller squeeze the internal tube at all/very little and there is a tiny, tiny, tiny chance that you get a backflow. If the dosing pump is connected to a KH or Ion director - I´ll think the chance is lesser than that MAC and Windows will be compatible one day

Never the less - I always have my pumps over the actual water level of other concerns. The joint between the suction tube (from the aquarium) and the pump head can can come loose. I have one pump where i can theoretical empty my 300 L aquarium into a 500 mL bottle. As chicken is my middle name - I have a check valve on the pressure side. Mostly because there is a chance that the tube can loosen in the joint that comes after the pump head and a backflow will be created. To use a check valve for the sample suction tube of both ION and KH director can affect the result - I will not recommend that. I´ll think there is a real risk of disaster - but not because a back flow through the pump head but because that the sample tube can be loose from the intake of the pump head. If you can fix a hose clam that fix both the 6 mm suction tube and the 4 mm pump head tube - you will be safe for that

Unfortunately it'll have to go in the cabinet under the tank(wife says so)

But everything else will be below it and where it'll be placed in the system worst that happens is I drop the water level below the pump and have 3 gallons or so on the floor so things could be worse

And it'll be tank to pump to kh direct to pump to waste so chances are pretty good it won't leak

But I guess I'll need a leak sensor for the 4e controller I plan to pickup also hehe

Guess I'm also building my own cabinet vs the biocube 32 one as I don't think it'll be big enoff lol

Right now it's on a temp(2 years opps) stand
