airstone / airpump for water surface agitation in non co2 planted tank - best practice | my aquarium club
I have had the plants with lights for a week now and they are growing well. I turn on the airpump with the lights are out. (haven't decided yet on a proper routine). But I realise that the minute bubble bursts make the roof, which is metal, wet.
So I was wondering, what's the more efficient method for creating surface agitation and water movement? Should I remove the air-stone and just leave the open end of the tube from the air-pump in the water?
Do you have a filter? If so, what kind? Most filters provide enough surface agitation for your purposes. When you really need an airstone is when you have your tank really warm, as the higher the temperature, the less oxygen the water will hold.
9l is only about 2g. ALL fish need filtration- this is not an 'option'. The fish you have in this tank are really not appropriate for such a small tank and require larger groups as well as swimming space.
You need one in order to monitor your bowl conditions. Plants do use some amount of toxins but this only applies to fast growing plants, not anubias. No matter how many plants you add, this will not make up for lack of sufficient space or filtration or inappropriate stocking.
