My questions basically in the title, I have a small, not overly powerful air pump (with a CO2 filter if thats relevant), which at the moment I have on for 12 ish hours a day when I'm home. I'm going to set it up on a timer I think so how long should it be on for ideally? I can't really have it on overnight as the noise keeps me awake.

My tank is non-planted btw - I would love plants but I'm having enough trouble with the water atm!

Thanks.

:-D

I only put mine on in a lightly planted tank at night but since your is non-planted you can keep it on all day.

Or you can not have it on at all. They are not necessary for the vast majority of applications, so it's really a whatever you want to do kinda deal.

Ah jolly good. That's great, thanks guys.

Just for future reference, if I was to put plants in my tank, what would I need to do then? With what has Nicolaas said leads me to believe air pumps have a part to play in planted tanks - although I thought it only oxygenated the water and plants don't need oxygen but CO2? Curious.

I'm pondering about plants with my ammonia levels....

Plants = no need for a bubbler

Of course enough plants, perhaps one individual medium plant per gallon, would also look after the ammonia for a reasonably fish loaded tank.

The bubbler does nothing for plants, in fact it removes CO2 so it is a bit detrimental but it won't kill them. I think planting to eliminate the noisy pump would be enough excuse to plant even if there were no other benefits.

there are people that will use bubblers when lights are off to gas off leftover co2 from injhection. unless you are using co2 injection there is no benifit from them and no harm either, they are for looks. but if you have a non co2 tank dont use a bubbler as you want to keep in as much co2 from the fish as possib even at night so that there is a nice buildup for the plants to start out with the next day.

In certain tanks, there is definitely a benefit to using an air pump. In addition to aiding in the gas exchange in tanks with minimal surface disturbance, air pumps also circulate water. So, a well placed bubbler can eliminate dead spots in a tank, where a powerhead or second filter would be too much. Dead spots are common in HOB filtered tanks - circulation is not one of their strong points.

I put the air stone on at night to put in oxygen when the lights are off, otherwise the next morning the fish are gasping.

I only have like 3 and a half amazon swords.

Sounds like you could use more surface disturbance, whether it be in the form of an air pump, an additional filter or just lowering the water level.
