Needing some direction with testing and treatment

[PoolDoc]

+ Post your test results --- especially the CYA test --- from the K2005. CYA levels are critical info, and pool store test strip results are horrendously bad.

+ Get a local OTO / phenol red (yellow / red drops) and test your chlorine. Do not worry about the alkalinity, but do keep your pH at the lower end of the range (7.0 - 7.4).

+ DO keep your chlorine in the dark yellow to orange-ish yellow range (higher than the OTO kit shows).

+ The Intex OEM filter cartridges are low quality. Better cartridges will not only last longer, but will filter out the residual cloudiness better. Read this thread:

Cleaning-your-Cartridge-Filter-wiithout-Damaging-It!

and use these links to order the cartridges you need:

Unicel C-4607 Replacement Filter Cartridge (Easy Set Size A or C) @ Amazon
Unicel C-5315 Replacement Filter Cartridge for 15 Square Foot Intex B Filter @ Amazon

I highly recommend using those links. Unicel or Filbur cartridges are what you want, but many online retailers make it hard to find them, by using deceptive language that is based on cheaper Asian made cartridges that are 'replacements' for Unicel or Filbur models. Unicel makes the OEM cartridges for many US filters.
