Hi guys- I have an E5 salt cell- from and old pool frog system— it looks identical to the A5 resilience salt cell you have here! Same connections- everything except it has a yellow top and not blue.... would you happen to know if I can replace mine with your A5?I would hate to have to return it!I can send a picture if you would like and would love to replace ASAP! Thanks so much-!Jim (Resilience A5 / D5 Replacement Salt Cell (also fits Nexa Pure/Ipure/Frog Hybrid))
