Noflex Digestor follow up

[Bob Bradley]

I started using Noflex Digestor in my holding tank last season after reading about it here. I was very pleased with the results. My holding tank vent went from hideous to zero smell within a week or so. I just went to reorder some and found that Fisheries Supply has it on sale for $16.50 per bottle. See: https://www.fisheriessupply.com/zaal-noflex-digestor-sewage-treatment-odor-eliminator-noflex

If you spend $100 or more, shipping is free.

Also, while googling to find where I wanted to buy it, I came across a review that did an experiment with the stuff. Interesting reading: http://littlecunningplan.com/2016/10/lets-review-a-product-with-science/

Interesting article, we also believe in theNoflex for the clean smelling heads alone, luckily I have a wholesale account at Fisheries Supply, they are a terrific company to do business with. John

Thanks for the heads-up Bob.

Thanks for the heads-up Bob.

I see what you did there.

If you buy this direct and buy 6 or more they will sell it for 16.00. You have to ask. Great product.

I have been using it and think I notice a difference as in less odor. Do chemical cleaning products kill the bacteria(???) that does the trick?

 

[Bob Bradley]

Chemical products should NOT be used with Noflex. They do kill the bacteria, including the beneficial noflex bacteria that "eat" the anaerobic bacteria which cause the stink. You should only use their cleaning products, as they do not kill the good stuff.

I use Nutralizerx now (used Noflex previously). The maker of Nutralizer has told me repeatedly that bowl cleaners, chlorine and strong acid will cause a reaction creating hydrogen sulfide within a minute or so of it hitting the holding tank. My SO was totally distraught to learn she could not loner use her SnoBowl cleaner!

Although not as good as Snobowl, i leave some nutralizerx in the bowl for 10-15 minutes, scrub with a bowl brush and it does clean the porcelain pretty well.

Bob, it is my understanding neither Noflex or nutralizerx contain bacteria cultures. Steve has done extensive testing of both his product and Noflex and they contain the same materials albeit in different percentages.

Great post. I use the Nutralizerx because I think it's a better product. It's also a lot quicker arriving coming from FL.

It does not take much of any chlorine cleaners to make either product useless. I try to do any of that cleaning prior to a pump out, but the remaining residue usually still defeats the product. It's impossible to pump out, refill and re-pump my 370 tanks while the p/o boat is alongside.

I agree that leaving some product in the bowl does a good job of keeping things clean. If you're using household cleaners in your heads, then save the cost of either Noflex or Nutralizerx and invest in gas masks. But, and this is a biggie, both products continue to liquify and that ain't bad news at all.

2x on using Noflex (or NeutralizeRx) as bowl cleaner. I sprinkle it around the bowl, let sit a few minutes, then brush. Seems to work great, and one less product on the boat. BTW, the sale is over at Fisheries Supply. I’m trying marinesan.com, 16.84 for 4 or more, free shipping over $75.

 

[wpc691]

Good experience with marinesan.com. Easy to order on website, Noflex arrived quickly. As noted above, 16.84 for 4 or more, free shipping over $75.

When we bought our 43 DCMY in 2016, the prior owners had dryer sheets in the master closet. Turns out they were masking odors from the shower sump below. Several issues needed improvement, but the sump still gave us odor issues periodically. Noflex down the shower drain works wonders. We always drop a bit in before leaving the boat for any length of time. Eileen BeckMaravillas1977 43’ DCMY

Good idea, I’ve been putting an ounce of bleach in there to kill the smell. I also clean it out about once a month so the slimm doesn’t take hold.

 

[Scarlett]

Rusty I do the same and also put some in the sink drains. John

Folks - just a warning about Noflex.

Used it on a Groco K head and the crystals fatally scoured the softer brass joker valve assembly.

This renders the unit unusable since it allows backflushing of black water past the rings. .. and the cost of a new assembly is strangely almost of the cost of a whole new head.

Beware with other heads and this product... or dissolve it first before tossing it into the head.

The company trying to the fix the head after this situation told me they have had other owners with a similar story.

I also use the Nutralizerx I use to use No Flex but also found the smell very harsh and it bother me I would put it in and flush it down because of the smell. The Nutralizerx doesn't seem to be so harsh and it works better IMO.

WE use NutralizerX and put 2 scoops down the deck fitting every pump out (weekly as we live aboard). A 1/2 scoop every other day which we let sit to clean and scrub the bowl. It foams and dissolves fairly quickly.

I have also begun to add 2 oz of a bacterial boost product and the vent odors are now completely gone. It costs $12/quart and after a month I still have 3/4 of the bottle. The gassing issue is, from my research, due to only having one vent for the tank which precludes any cross ventilation to the tank. This allows the anaerobic (stinky) bacteria to thrive.
