Bubbles at the top of my tank???


So I have recently gone to a planted aquarium with no air pump. I have a HOB Filter and thats it. I dont have a power head to move the water either. I like the still look but I noticed that I have developed some small bubbles that wont go away at the top of my aquarium. Im okay with them but Id like to remove them.


I have heard of several reasons for this that could be my problem.


1) Bubbles can be a sign of too much conditioner. I must admit I never manage to dose a single drop per gallon. That thing drops fast!!! I use the large bottle of zip drops and just quickly turn it upside down.


2) It can be from adding a fertilizer or additive, I use Tetera Floura Pride.


3) It can be from turning up your substrate, I use eco-complete and have not been able to find a setup im happy with While I wait for the plants I have to grow out.


So what do you guys think? I dont have any scum or oil on the surface.

Let me know...

Alex R.

If the bubbles are from a surface film of some sort, I'd try a surface skimmer. Hagen makes them to fit Aquaclear HOB filters. Very clever design that works well.

Or you could use an airstone to agitate the surface and keep the surface film at bay that way.

I know you say you have no surface film, but something has to be making persistent bubbles like that.

You can always do the finger test. Touch the bubbles with your finger and see if all of them pop. If they don't, I think it means something is wrong with your water quality.

Yes it could be gas from the substrate but if your tank is new 1 month-3months its not gas.
If its always there its not gas. it could be because of a overdose of conditioner.

yah use the finger test i use it to find if its co2 or air or other stuff. I have lot of water movement so i don't care if there are bubbles because its usually air.

Also, if your water is not all the way to the top of the tank, it could be the HOB that is making these bubbles through the surface splash.

The tank is not new. Very old and very established. I dont have a surface scum. The only thing wrong with the water is high nitrates.

I dose diy co2 in the tank and I notice the substrate and plants releasing large numbers of small bubbles constantly.

Thanks

The CO2 is the source of your bubbles. Really not a way to avoid them unless you get rid of the CO2 injection. You can introduce some surface agitation but you will always have bubbles in your tank.
