skimmer tunze 9002 micro bubbles

[acidjc]

hi all

I have setup a new 28gal JBJ nano tank yesterday and use my tunze 9002 in the middle compartment. And notice there is lots of micro bubbles coming out from the bottom of the tunze skimmer. This issue did not happen when I use the tunze 9002 in my old 24gal JBJ nano tank.

I have checked and there is no crack or broken part in the skimmer, I even take out and replace all part correctly, washed and clean. But the micro bubbles still coming out from the bottom and being suck to the both side chamber where the return pumps are.

really an eye score to see so much micro bubbles coming into the tank when the light is on.

The tank is still newly setup and under going water cycle process now.

can any advice me why the tunze 9002 skimmer is giving out micro bubbles in my 28g and not in my 24g tank?

anyone encounter similar problem before can kindly help to advise how to resolve this issue.

one thing I notice is that when I use my skimmer in the 24gal, it hold on to the chamber using the magnet, whereas now in my 28g I have remove the magnet and it now tight fit into the middle chamber. Hence the water inlet to the skimmer at the bottom should have been block by the chamber walls. will this cause the micro bubble issue???

should I drill a few small holes on the other sides of the skimmer to allow water to flow in better???

Thanks a millions

Bubbles in tank can be caused by water level being too low in the chambers on each side.

I modded mine with one of the tunze magnets inside the chamber. It then fit nicely and snuggly into the central compartment.

so the micro bubbles is caused by the low water level?? hmmm... but the the back of the tank (IOS), I can see that the water level is reaching the marking on the skimmer. (since the 28g JBJ tank back is see-thru),

beside low water level, what else can be the cause? if I drill 2 small hole on the side of the skimmer, will it increase the water level since there is more water flow into the skimmer now?

I'm talking about the sump chambers on the left and right of the IOS, the ones where the returm pumps are. If water level is low, it will cause micro bubbles to be created by the force of the dropping water and gets introduced to the tank by the returns.

As for the water level for the skimmer, you are right. Just keep the waterline exactly on the line marked on the skimmer body.

You might also want to check that the component inside the skimmer and correctly placed. might have shifted during shipping ang handling.
