The commercial evaluation is positive but I will be able to evaluate the effectiveness of the product only after the winter season and storage are finished, hoping to find clean water and tanks. Nothing to say for the moment

I use it annually with the best results.

fast and practical

it's OK. What should you write about it?

Product - as far as can be determined - good, but for larger boats with a corresponding fresh water tank there should also be larger packaging (of course with a price advantage !!)

I used this tank cleaner for the first time. First of all, a bottle is only for 160 liters, which is quite little since our tank holds over 300 liters (so two bottles ordered directly). Then poured in and left in, and rinsed out. No effect to be seen, ie no impurities loosened from the pipe and rinsed out and even worse after the second filling, I brushed my teeth with the water as usual. The water tasted totally sour and made the mind very dull. After filling 4 tanks (each time over 300 liters), the sour taste is gone, but a dull feeling in the mouth still remains. Conclusion Hardly feels any effect, only the tank is rather contaminated (the agent is also quite poisonous) - I would not buy it again

After cleaning the tank exactly according to the manufacturer's instructions, it took 6 complete fillings to make the water taste neutral again! Never again and with 440l per tank filling it's a waste of water!
