Pools in question are not the pool in signature:
Have two pools in question,
Pool #1 will be going over soon to SWG, it's vinyl and has a automatic cover with tracks below the coping with an above water header bar.
Pool #2 is currently SWG from a few years back , is vinyl and does not have a automatic cover so no tracks or header bar to speak of. I didn't see any sacrificial anode anywhere. Pool hasn't been opened for the last two seasons .Pump motor was just changed out because shaft was frozen with lots of galvanic corrosion on the back end of the motor. The rotary seal along with the other gaskets/seals where changed too. Looked like the rotary seal had been the culprit of the shaft issue with lots of galvanic corrosion there too.
I've seen much discussion about zinc and magnesium anodes and if I'm understanding correctly the magnesium is only necessary for pool #1 with the tracks and header bar made out if aluminum. I would like more clarification on what goes where such as zinc non bonded in the skimmer baskets and magnesium or zinc connected to the bonding wire, buried in moist soil next to the pad where the bonding is easiest? Are there any particular magnesium's or zincs better or worse for this purpose and is size of importance.
Thanks in advance, Allan
