Has anyone tried this?

We're on a mooring, and our cruising grounds are NDZ's. We always use the holding tank. After it's pumped, I put 1/2 of an 8 oz. bottle of Thetford Camper Chem into the toilet and pump it through. A whole bottle treats 40 gal., and I think my holding tank is about 22 gal. So far, so good.

I was always thinking that an automatic metering system would be cool. Maybe more trouble and complexity than is worth it?

Has anyone tried this?

"Inline" treatment cartridges first came on the market in the late '80s...none of 'em has ever lasted very long. I've never been a fan of any of 'em...they're expensive, often messy to refill and can react negatively with tank products. There are much better--and far less expensive!--ways...starting with switching to a tank product that isn't hazardous to your health and works WITH nature to PREVENT odor instead of killing all the good bacteria along with the bad in an effort to eliminate odor that's already been created. No-Flex Digester Noflex Digestor is getting rave reviews from everyone who uses it.
If your aim is to eliminate odor from sea water left to sit and stagnate in the intake line and pump while the boat sits, you can solve that problem for about $10: reroute the head intake line to tee into the head sink drain line below the waterline as close to the seacock as possible. That lets you continue to flush with sea water (Tartan used to plumb their heads this way to eliminate one thru-hull...I got the idea in the mid '90s from a Tartan owner.). To rinse the sea water out of the system, close the seacock and fill the sink with clean fresh water, flush the toilet. Because the seacock is closed, the toilet pulls the water out of the sink, rinsing out the entire system--intake line, pump, channel in the rim of the bowl AND the discharge line. Also makes winterizing easy: close the seacock pour the antifreeze down the sink and flush.
All this is described in detail in my book, btw....

Thanks, Peggie. And I have your book - maybe I should read it! :)

But Peggie, I read your book and started using KO and CP many years and boats ago — with “happy wife” results. (Was even able to add cross ventilation on one ) In fact, she tells all about KO & CP. So, why Noflex?

K.O. is an outstanding bio-active (live bacteria) product, but live bacteria need plenty of oxygen to function aerobically--which is how they prevent odor. Not all tanks are sufficiently well vented to provide enough oxygen to do that. Some are...and most, but not all, tank venting can be modified to provide enough oxygen--you obviously did that on one boat. However, K.O. was actually the very first bio-active tank product--the first that wasn't a toxic chemical (born of a desperate need to solve the odor from my own holding tank!). It was a pioneering breakthrough in holding tank maintenance. But that was 30 years ago...and like everything else, tank product technology/chemistry has evolved. Other bio-active products have come and gone. Organic and non-toxic chemical products have been developed that don't need as much oxygen to function aerobically...and a few of them work VERY well. Today No-Flex is the best. But if K.O. works for you, keep using it!
However, C.P. is still not only the best bowl cleaner for use in marine toilets, but it's also the best sump and drain cleaner on the planet!

BUT PEGGY — you created KO and CP! And saved me from “that smell”. How could anything be better?
Seriously, thanks for keeping up to date, and informing us, on a very important “keep the admiral” happy area.

I use ODORLOS in a fresh water system with very good results.

I know...along with several other equally good products. And when I sold the product line to Raritan I knew how it feels to see your children grow up and leave home. But it's very rewarding to know that we pioneered a whole new approach to holding tank maintenance...a"bandwagon" that others--including Odorlos (which I really like, btw)and No-Flex--have jumped on and are taking it even further.
