Lifting Power of Peristaltic Pumps

I have some dosing pumps that i would like to return to service, but a condition I have is that the apparatus (fert vats and pumps) must be below the aquarium. Those who have experience with peristaltic pumps (the type very typically used for dosing) may be able to give me a clue as to what I may expect if I want about a six foot lift. Is this too much vertical distance? I will experiment for sure, but thought it would be wise to get some comments first.

 

With my current setup, the wet/dry arrangement is not feasible. Although I did consider engineering a small sump loop for this purpose, I wanted to consider simpler methods first.

Tom, if I understand you, the fert vats can be below the tank, but the pumps themselves should be above, so the long part of the path is the draw side, avoiding head pressure on the output side. This is the best overall arrangement anyway, so that's great.

My plan would be to keep the fert vats high, so the bottoms of the two litre bottles are maybe 5 feet below the surface of the tank water, but I will need to go about 3 feet horizontally. Do you see difficulties in this? If not, I will set up an experiment and test it.

Thanks. Regards, Paul G

 

I managed to arrange for the fert vat/dosing pump to be inside the cabinet under the aquarium. The total height from bottom of vat to aquarium rim is 58". The original location for this was on top of the hood, which of course worked fine but was just too unsightly.

The Aquamedic SP3000 runs about 90 seconds every day. There does not appear to be a problem with getting the needed lift.

Using API Fungus Cure does prevent clumpy scum buildup in the vat - a tip I picked up, I think, on this forum. I also aerate it with a small stone.
