Help with bubbles

[nicreef]

Hi,

to increase the water capacity in my tank and fit my small office space, i have been using a rubbish bin as my sump. However, this does not allow me to build a baffle. as such my display tank has lots of small bubbles floating around (look like dust floating around the top of the tank).

using the attached container so that the larger bubble does not appear but still having loads of the small dust like air bubbles.

also attached is the picture of my sump to see if anyone has any idea on what to do. I am also using a sock at the intake point to lower the bubble.

from what i can see from the pic, I think the problem lies with the pump and the skimmer being put too closely together. (if that is a skimmer I see in the pic) cant really tell your setup from the pic.

If its a skimmer and if your skimmer allows, try directing the skimmer's water exit upwards so that the water comes out from the top of your sump and the bubbles dissipate from the top. or let the skimmer water land on a pieace of filter wool. that should reduce the bubble

ahh ic...think that is where my error is at. i am currently placing the exit of my skimmer next to my intake (was thinking better to send as much water out of skimmer to tank) haha.

kk. gonna try let the water exit upwards out from top of sump since that would essentially put it far away from my intake point which is right to the bottom.

hmm dint work use my pipe to point out of water onto a portion of the rubbish bin before flowing down but bubbles still coming out as usual.

Are u having a sandbed? It might be sand being stir up too.. Cause I also thought that I have micro bubbles.. Until I see clearly that it's sand.. Now adjusted the direction of water flow and all solved! Sent from my LT26i using Tapatalk 2

yup i have but definately micro bubble. moment i off my inflow, everything is ok. inflow pipe is pointed into a cup right now before flowing out so disturbance to sandbed by it should not be the problem.

can try make a invert U shape of your return hose to trap the air bubbles...

hmm think i already have a inverted u shape coz the pipe that is coming in is kinda hanging on to my tank. not sure if that is what you meant hehe

but anyway due to some problems with my table, i had to take water out of my tank and take out my rocks to move my tank and replace the table.. After i put it all back, somehow or another the bubble is all gone all of sudden hehe.

think is because the cup is resting higher above the water liao. i am not too sure ;p
