RO external skimmer help

[demifelix]

I had been using my RO DNWB-110 off an on for the past year, and recently I found that there's no bubbles mixing in the chamber. The recirc pump seems to just pumping water around but the water does not mix with air to create bubbles at all. Is this about time to replace the pump or is there anything that can be done to fix this?

Most likely scenario is the air line that supplies air to the pump is clogged with salt creep. You can either remove the line and clean it, or pour a small amount of hot water directly (and carefully) into the line.

I'll give that a try tonight. Thanks for the tip.

I have an octopus skimmer and every few months the salt creep will block the air line and the thing produces ZERO bubbles.

I have started taking my skimmer apart every 6 months or so and soaking the components in a vinegar/water bath over night. Works like a charm :thumbs:
