aqua lifter pump

[markandkristen]

ok i have one of these in my junk drawer and was curious how i can make them into a auto top off for my 10 gallon tank

i did a search and didnt get much results

Wire a float switch into one leg of the Aqualifter, install the float switch in the ten gallon tank at the desired level, run an airline from the input side of the pump to a bucket of RO water, and run another airline from the output of the pump to the tank, when the level in the tank drops, the floatswitch will activate the pump until the desired level is achieved then automaticly turn off.

check out aquahub.com, substitute the pump in the picture for the aqualifter.

Also, dont forget to have your top off water at or below the waterline of your tank, and leave an air gap between the top of the waterline and airline exit to prevent siphoning.

Please dont flame me but you can just get a digital timer and set it to 1 min each day. Adjust the tube up or down until you get the right amount. I did this for years on a nanocube with no problems.

Here is my topoff setup. Simple, effective, reliable.

There is a piece of rigid tubing inside the Brute container; soft airline is not the best medium to get the water at the bottom of the container. Placing the Aqualifter pump above the source combined with the piece of 1/2" clear vinyl tubing and a check valve provide anti-siphon fail safes. The float switch is from auto top off dot com.

i've used an aqualifter for years for topoff, with a reefgeek level controller with two float switches. float switches will eventually stick on you, and having the high water cutoff is important. also using a small top off vessel so you won't flood/massively dilute things if things go really wrong is not a dumb thing to do.

no flames; but wouldn't this only work if the rate of evaporation remained constant? if the rate of evaporation changes aren't you having to adjust your timer just as often to match?
