It is totally normal. They don't know their rump from their elbow. 'Chlorine' pools use Sodium Hyperchlorite, and everything else added to the pool either is a salt, or breaks down into salt.Is it normal for pool companies to state that any issues to pool due to salt is not covered under the warrenty?
Yet nobody ever voids the warranty on the 'chlorine' pool when the salinity reaches 'salt pool' levels from all those additions containing or breaking down to salt. Nobody even tests it. Ever.
Call it a 'salt pool' and everyone loses their minds.
I'd skip the tab feeder. Tabs are very slow to dissolve when it's cold. The demand is real low too, so it's kinda a wash, but it's one more thing to wonder about and pay attention to.Also will the supplamentary cartridge make it easier/automatic to add chlorine when the temp falls below 60 or do you have to add this manually anyway?
The acid in the tabs eats the feeder and many are wonky before long. Then the flow is never right and folks can't get them to repeat what they need week over week.
Using tabs in a tab feeder will also leach acid into your equipment when the pump is off. We recommend using the floating tab feeders in the pool itself if the need arises.
