Large or strong enough air pump without going with a blower?

[eklikewhoa]

the best comparison I can think of for the sound is a like a small crappy bilge pump. For me it's pretty loud but for what it's capable of no it's not.

It came with a diffuser that splits into 12 I think, Seeing how it does the 4 I have now I think it would run at least 20 sponge filters for like a 20-30g tank.

Did it come with a splitter valve?

how loud is it.you think it would run 10-15 airstones.need something for home,so if you get bored with it in the next couple days,just let me know.thanks

went for the Pondmaster AP-20 but with the coupon code and free shipping with min amount order I upgraded to the AP-40... this thing is clearly meant to circulate a small part of the ocean...

This thing split into four airstones is strong enough to cause a volcanic eruption of flow that forces water out of a 200g tub. I think they use pumps like this to operate moonwalks.

LMAO!

I wonder how loud this thing is ?

I'm wondering the same.
From what I read on other forums it's fairly loud.

Here's another option I am thinking about going with.

No one with a big tank using air pumps?

[eklikewhoa]

like a forced venturi.

I'm not looking for all that, just need a simple and strong enough air pump. I will be running airstones.

[wesleydnunder]

I tried an experiment when I went home for lunch. I ran my air lines to the powerheads which are low down on the right side of the tank. I inserted the ends of the air lines in the little ports on top of the exhaust port. The added venturi from the powerheads was enough to assist the air pump and got a nice volume of air blowing out of the powerheads. It's gonna put some microbubbles in the water but I think the additional water movement and oxygenation will make the fish happier.

Yeah that's what I figured.

Looks like the only viable options are the pondmasters or jehmco pumps, reading a lot of not so good reviews on the coralife luft pumps.

I'm having the same issue, Quoc. A reciprocating pump is limited by the pressure it can exert on its piston seals.
