Intex Salt system and Sand Filter Question

[PoolDoc]

I don't know why a sand filter would be incompatible with salt. However, I'd guess that Intex does, and that if they say it's not compatible, it's not. Your best bet is to call Intex. However I'm not sure that will help - they are very good at sending out free replacement parts, but all the agents I've talked to are non-native English speakers so that even if they explained what was going on, I'm not sure I could understand.

Intex does suggest replacing cartridge filters every 2 weeks. You can improve filter performance by using better cartridges (links below) but you won't necessarily go longer between cleaning.

========================================

The OEM cartridges in Intex filters are not high quality. The Intex manuals recommend replacing them completely every 2 weeks. A BETTER option is to replace them permanently with 2 - 3 Unicel cartridges, and rotating them through a cleaning solution. Properly maintained, the Unicel cartridges will last all season AND will filter better. So even though they cost more per cartridge, they cost less per season!

But, purchasing them is tricky. Amazon does not reliably stock them, and some of the 3rd party sellers are charging high prices and/or high shipping. So, check the Amazon link, but watch out for the prices and shipping costs.

It would be nice if you could just buy them elsewhere, but many of the online pool stores are listing Pleatco or other Asian made low quality filters, as "Unicel C-4607 type" or "fits Unicel C-4607". So shop carefully!

Here are the Amazon links:

Unicel C-5315 Replacement Filter Cartridge for 15 Square Foot Intex B Filter @ Amazon

I Figured out the issues. A 6110/6120 SWCG from Intex are rated at 1000 GPH flow rate. The new pump is rated at 1650 GPH flow. I looked at two other SWCG a 8110 rated at 1600 GPH flow and a 54601EG which is capable of 4000 GPH flow. I guess we will upgrade the SWCG to accommodate the new pump.

Sorry for the problems!
