Marina Cool Air Pump

Worked for about 24 hours, then it stopped pumping air even though the motor was running.

Ideal for small hospital tank

It was perfect for my small tank for fry

A very quiet but very feeble little pump. I don't have a big tank, just 55 litres. The Marina Cool however when attached to a single small air-stone produced only a weak little trickle of air bubbles. I changed the stone in case it was a duff one but it made no difference. I've now abandoned this pump and got a bigger (though much noisier and more expensive) one which produces a great curtain of air bubbles.***************************************It's been pointed out to me by William that this pump is specified for tanks of up to 20 litres. I can't think why I didn't see that when I ordered it, I usually pay attention to such details when buying. Apologies to Marina and I'll upgrade my stars accordingly

I've bought this unit to help aerate the water in the tubs that have my Koi fry in them...It's pretty quiet provided it's not allowed to touch anything on the sides and has run for about 9 to 10 hours a day since I received it with no problems or heating issues. It has one outlet which I then run through a valve system to supply 3 tubs...and works really well. If you've a large aquarium or small pond [providing you protect the unit from rain etc] I think it'd easily run a tubular or disk bubble stone and if it only last me for this year it was money well spent.

Very small in size, good value for money. A bit noisy, but does the job it was bought for.

Good

This is the 3rd pump I have head to buy as they stop producing air there is no way of contacting the seller my fish actually needs the pump to survive to I always just click this one as its quickly delivered and reasonably priced but buying 3 isn't its costly.
