Clear, but no chlorine???

...ANY cartridge or filter media is a potential reservoir of accumulated oxidizable 'goo'. 2. For the same reason, clean the filter cartridges. Be sure to do it correctly. Spraying them off (with the hose; NOT with a pressure washer!!) is a good intermediate cleaning, but a full cleaning, which should remove any oxidizable 'goo' that could create chlorine demand takes more. See http://pool9.net/cart-clean/

Still want you to do this..... Can't hurt and can only help.

I did read the post by Pool Doc about cleaning cartridges- saw a couple videos as well. I already have a set of hosed-off filters awaiting a TSP soak.
I am reluctant to clean the recently added cartridges because they were added right before I started shocking, and were new and clean and the pressure has risen very little since then. Plus, honestly, I am still leary of doing this by myself- so I'll want my husband to "help" (maybe he'll get really good at this and it becomes his job-ha), but his availability is limited. BUT i hear you- it's the only thing left to re-check, right?
That's why I mentioned that perhaps pouring bleach directly into the skimmer could maybe help. I read that it helps clean the sand in sand-based systems, but have never read anything about cartridges.

Your pool has undergone a lot since you started shocking. Get the hubby on the job! Just my recommendation.

The filters have been exposed to high level chlorine the entire time they've been in service, I don't think adding bleach to the skimmer would make any difference. I know it's frustrating but I think some more patience and sun will get you there.

So keep up the testing and add bleach as needed to maintain FC 30?
Btw: my husband just got out of the pool- he's been in it several times now during the past few weeks, and for the first time he noticed that the water had a bitter "taste" to it- whereas in the past- even this Friday, it did not. (Not that he regularly drinks pool water). Ever heard of this before?

I've experienced it, but I don't know what it means. Generally, sour means acidic and bitter mean alkaline, but it's not necessarily caused by the pH. I suspect it's stuff the chlorine metabolized but hasn't yet been filtered out.

Agreed. Sounds like CC. Ever taste hotel pool water???!!!
