When we moved here and inherited an inground pool with a Nautilus DE filter that has been working ‘well’ last three seasons i.e. water is clear.
I installed solar panels so spliced into the return and diverted water up on roof through panels and back into pool, which works great.
However, on start up I began to get a few bubbles from one of the return lines I wasn’t sure if this was a problem asked around and got blank stares…
Now I notice on normal start up (not just after cleaning and recharging the DE) the return line bubbles like a Jacuzzi for a minute or so then sends a plume of green (DE?) into the pool before calming down and acting normally i.e. clear water being returned. I have two other returns and one also does this but to a lesser extent the other just seems to return clear water.
Im thinking this is a major overhaul for the filter replace 'fins' new seal etc or is this a bigger problem.
The pool is scheduled to close next week so i've got a couple of days to try any suggestions.
Thanks in advance
