And here's yet another question from a new and confused pool owner.
We just opened our pool for the first time this year (bought the house last year). It had been closed for about 4-5 years the neighbor thinks. Whoever "winterized" it, and I use that term loosely, cut the hoses leaded to the pump and from the filter. There were originally 2 return hoses. The pool guy we paid to open the pool said you really only need one, but having read a great deal over the past couple of weeks, I get the feeling that if the deep end return were hooked up, it would vastly improve overall circulation and we would not have little algae issues in the deep end. Right now, little lumps of it are forming regularly--I think it's green, although it looks brownish. The water itself is crystal clear and chlorine and pH levels are in the ideal range. (We didn't buy an elaborate kit, because we didn't know. We are using 3" tablets in a floater, because that's what the pool guy said to do. Live and learn.)
Anyhoo, we believe that to reconnect this return, we would attach a pvc t-connection, then run a hose from each side. Is this correct? Fingers crossed the pictures worked, so you can see what we're dealing with.
