Sounds like it is somehow sucking in air. Can you take the filter stuff out, (what you can) and then put it back together. This might fix it

Do you mean your return pump?

Hi, yes my return pump? That is what I meant.. it seems to be blowing out quite a lot of bubbles I’ve taken the filter sponge out and rinsed and cleaned in ro water I’ve turned the filter off faced the return nozzle upwards as it was facing kind of downwards still no difference? The water levels where the return pump is so look rather low if I say so myself I’m just confused on what I do??

Yeah I think so the water level in the section my return pump is is rather low not sure why this has happened, I will post a pic so you can have a better insight of what’s going on

It is from evaporation, any evaporation is going to show in your return chamber (all the other chamber and the display will stay at the same level). You need to either regularly top it off with RODI water manually, or get an ATO. You return pump is sucking in air because the water level is too low.

Thankyou! I actually have an ATO that came with the tank and if I’m totally honest I’ve only filled it up twice in 10 days and it apparently only lasts 3 days but I didn’t think this would happen because I didn’t use the ATO on the regular but it seems like you know what your talking about so I will start topping it up more regularly see if that changes anything

Does your pump have an intake sponge? On my Danner pump, I have to make sure the sponge has the large side down, narrow sides vertical. Also the sponge has to be 100% seated, or I get a tiny Vortex sucking air in. Also when I clean the sponge, I turn it over several times in the sump, squeezing the air out of it.

Just filled the ATO and within seconds my tank cleared with no bubbles coming from the return pump! Mission accomplished thankyou everyone! Deffo gonna keep up with those ATOFFS
