Filters AND air pumps ? #1
Me again!

I'm getting confused with filters and air pumps ... do you need both?

Say I had a Fluval 2 plus filter ... do I need an air pump as well, or does the filter do the aeration as well?

Because I've started with a Bi-orb, I really don't understand how things work in a standard tank.

Thanks for helping with all my dopey questions!

The main thing you need it the filter to keep the water clean and if you have the outflow so that it moves the water at the surface then it will aerate it too, but we usually have an air pump so that we can have an airstone that creates bubbles and aerates the tank "I think it looks nice too" the bubbles that is not the pump you can also have a decoration which bubbles like a chest see older Rena photo if you dont know what I mean

Re: Filters AND air pumps ? #3
I have the 2 plus and it has a periscope part to the out flow of the pump which when it is above water level creates a stream of bubbles in the outflow jet of water.
so no air pump needed. Mine produces an annoying amount of tiny bubbles that circulate the tank.

Goldy how much movement do yo u need?? is it enough to have a slight ripple or does the water need to be broken??

Saw an advert in the magazine for an air pump that is total submersible rather than have a tube from an external one to an air stone cant find it at the moment but it looked good, not sure if mains powered or not tho?

you dont need an airpump as long as the water ripples, the outlet nozzle should be just under the waterline, making a rippling effect, airstone and bubble walls etc are decoration only. di

I would think the tiny bubbles are actually aerating the tank

Guess it depends on your stocking level and yes the water surface needs to be broken for the water to absorb the oxygen

Re: Filters AND air pumps ? #6
I've got one of those pumps, and let me tell you, they're NOT noiseless.
What I mean is the bubbles are very loud, but there is no buzzing from the unit when it's plugged in but turned down.

It's just a variation on the venturi on most internal filters, and even if you turn the air adjuster right down, there are still bubbles.

Best to try and see one in action before purchase.
On the other hand, they're quite cheap

Re: Filters AND air pumps ? #7
Yeah but thats not the pump is it its the water moving I kind of like that noise.

Yeah it was practical fishkeeper, found myself in smiths looking for something to read and came across the mag.
Its got some good stuff in it.
good pic of a panda catfishy fish.deffinatly my next purchase I think. although that wont be until march now as the powers that be have decided I need to go and set up a new store for Jan/feb, so wont be able to look after new introductions. Mind you it has its advantages, 5 nights b&b a week in a pub

Anyway back to the pump yeah thats the one looks good to me, the only problem i can see is that the flow in my tank would disrupt the upward bubbles and cause them to circulate the tank ending up with the same issue.
Ive a day off tomorrow, cant remember what one of them is or what im sposed to do but going to have a play with the pump to see if i can sort it out better.
