What is the smallest GPH pump available?

[astrick117]

Hi everyone,

I'm just jumping back into saltwater tanks and used to use a TOM aqualifter for my ATO. I loved it because I never had to worry that it would overflow my sump and if it ran dry it wasnt an issue.

Unfortunately it seems like in the past two years it was discontinued. Is there a suitable replacement? If not what's the smallest GPH utility pump that you guys have seen?

You can use any smaller sized single continuous dosing pump

You mean like a tunze ATO pump, or the like? Some of the biocube and AIO pumps are pretty small.

I believe this one is a good substitute for the tom aqua lifter

BRS 1.1ml/min doser. Cheap and bulletproof.

For ato the brs 50ml pump should be good also

I believe the brs doser is a peristaltic pump.

Tom's aqua lifter was a diaphragm pump

Thanks Everyone! This is incredibly helpful. I spent way too much time trying to google options and literally nothing came up, so Im glad I asked here. I'll take a look at all of the options mentioned

How much height do you currently have between inlet and outlet?
