Hey everyone, I wanted to install a Stenner pump to my ~2500K spa to automate chlorine addition. The spa with a solar cover currently consumes ~10 oz bleach per day in the peak summer (100 deg now!). I'm assuming it consumes around 2-3x that without the solar cover.
I run my pump only half an hour a day (the pump is rather big for the spa) with decent results; don't really want to run it more than 45mins a day so my pH doesn't rise too fast due to aeration.
I was thinking of getting a 10gpd variable speed pump (45MHP10) which would be able to inject a max of ~26 oz in half an hour which should give me some safety margin if the solar cover goes away for some reason.
But do you think that might be cutting it too close? And would I probably have to run my pump longer after the Stenner finishes injecting to mix? Do you think I'd need to get a 17gpd pump instead (max 45 oz in half an hour). Thanks
