What size air pump ?

[Morpheous]

Hi Guys, I'm in the process of slowly buying bits and pieces for my new 230L tank. I was wondering what size air pump to use ? and an idea of cost ? I am planning on only using it to run 2 Large airstones running the length of my tank

( 1140mm ), an ornamental waterwheel, and a submarine that floats to the top and sinks again. I am running an external cannister filter so don't need the pump for Under gravel filtration.

Thanks

Glen

This wont be that much help, but different makes are better than others and i used to favour Rena. What i do remember is most are under-rated so whatever they say get the next one or two sizes up. Redwood aquatics down here in Chch are doing some MEGA air pumps (silent too almost) for $99. They have 8 outlets attached. I can recall a few years ago they were huge money for that sort of kit.

Good luck though.

Basically the bigger the better, as big as you can afford, when i started out i bought a couple that would do the trick, then wanted to add more airstones so had to buy more pumps, if i had just bought one 4 outlet would have saved two trips to LFS and would have been much cheaper.

All smaller air pumps work the same way (well most do) they have a diaphram that brakes down over time and is not covered by warrentee.

A cheep air pump that puts out a good amount of air is the cosmo range, it is available at Critters on Thackeray st in Napier

Good luck
