I have some good news in that the van's grey water tank float is now working correctly. It wasn't up til yesterday, so I drove the van home and flushed out the tank several times, then poured the remaining Noflex into the tank (about 3 spoons full) and this morning we have success, it's working perfectly." Bill - Sydney

Here is another video showing a demo of just how good Noflex is:

Credit where credit is due. We have had one head on our Cat that gave never ending problems with a smell. I have tried everything , the holding tank resembling some kind of awful chemistry experiment at times. Had minor success a few times but the smell always returned. One dose of Noflex down the pump out hose and flushed through with clean water. One dose in the head and flushed through with fresh water and left for 24 hours. Before this I couldn't even open vents on the tank to inspect without feeling quite ill for a long time afterwards. Now , absolutely no smell or sign of sludge anywhere. The inside of the tank looks pristine. By far the best product I've ever used. No more masking the problem but dealt with it once and for all. Thanks. Simon OCT 2017

Hi Jenny,  Just a quick note of thanks. Your customer service is fantastic and your product Noflex is amazing!  We have battled with our septic system and the gas build up in the pipes causing a dreadful lingering smell in the toilets. Within 4 days and 3 small doses of Noflex the smell has disappeared.  Can't get better than that.   Kind regards, Deb. July 2018

We met once when you so kindly dropped our last order to us in Avalon Beach. We are using it in our septic tank on our property on the north coast and it is fantastic stuff. It seems to be working very well, no more smells! Thank you for selling such a wonderful product. We have given away one jar to our neighbours up there and they are very happy with it as well. Kind regards, Renee 

A great endorsement from an expert on marine sanitation.

All the controlled testing in the world doesn't mean as much to me as consumer experience with a product. 5 years ago no one had heard of it's available from every marine store and and online retailer I see, and boat owners everywhere are raving about how well it works, especially at dissolving sludge. Availability and distribution don't impress me but -0- negative comments about it does...and as the old saying goes, "50 million Frenchmen can't be wrong." Odorlos is still an excellent product and so is K.O. But they can't dissolve sludge and No-Flex can do everything both of those do AND dissolve sludge. That's enough to convince me to recommend it where appropriate.

"We used product, it got rid of the smell in the bilge, very pleased with it. We also used it in a vacuflush cassette toilet system last week (Which smelt very bad). It not only cleaned it out but got rid of the smell - Very happy.

Article 'Which Holding Tank Treatment is Right for my Boat?'

"You can try the super effective and highly recommended Noflex Digestor from Zaal - Which is a Peroxyl based powder that releases micro-bubbles of oxgen that break up the sludge and promote the growth of naturally occurring aerobic (good!) bacteria - which inhibit the odor causing anaerobic process (the super stinky gas). Noflex needs to be added regularly and, like some other treatments, must not be combined with any other treatments or chemicals to work effectively."

The white porcelain of the head (toilet) on Naphtali, my sailboat, was black from the water level to its hole in the bottom where the water etc. goes into the pipes. I think in my cleaning it with Lysol or something, there was a reaction between the chemical and salt water that turned the porcelain almost black. I thought I would have to replace the toilet; I could not scrub it, clean or do anything else with it. Fast forward to Noflex. I have put the powder in the toilet and let it soak, flushing the thing every few days or so, and reapplying the powder. It foams up and is clearly working. We were gone 5 weeks back to Ontario, and the powder sat in the toilet all of that time. It has taken this long, but the toilet bowl is almost completely white again, with only a small trace of the stain in the porcelain. I'm sure that if I keep at it, it will come completely white again. There is no smell anywhere in the head.
