Hello carnut. If you have a good working ozone system you should not need to shock the system. There are a lot of ozone systems out there that simply do not work well, if at all, and it's not easy to field test one. The easiest and simplest way to check it is to pull off the oxone injection hose and take a small whiff of the gas. It should produce a slight burning sensation. DO NOT stick the hose up a nostril, just a short whiff. If you don't get that then it's either undersized or not working.
If you have a foaming application prior to the mitter curtians, play around with a good low ph detergent. The majority of the bacteria Forming on cloth tends to flourish in a high ph environment. Significantly dropping the ph can clean and prevent further bacterial growth. At least that's what it has been with my experience.
Ditto.
Once you get your cloth clean, this is the best way to prevent reoccurrence of this problem, so you won't have to go through it again.
In fact, even if you currently do not have a foamer prior to this mitter, this is probably a good reason to get one. Extra lube on the cars, and your cloth stays clean. A lot of the low pH solutions are easy rinsing, so even if this is further down your line, it should not cause a problem.

We do have a low PH solution just prior to the Mitters. Ahh, alas another piece of the ozone has gone out and it stinks to high heaven coming in the tunnel. Ordered new part..check valves... and dosed the pit with clorox in the meantime.
The people we bought our reclim from have gone out of business and so we have to get service advice from the ozone component people or the reclaim tank people but neither seems to know the other businesses connection. Frustrating!
