Ozonizer ET200 200 mg Suitable for Fresh Water and sea Water,can Work with ORP Controller

Using it with a air pump forcing ozone and air in my protein skimmer to increase the orp in my saltwater tank.

For the money????? This is not a small system in the least, shy of 500 gallons and just blowing in open chamber no dryer and abusing and has been about 100 days. Update. Now been 10 months maybe and thing is great. Does need to be cleaned. Most importantly! Make sure you do you have device in the sun! And under 90* as will get stupidly hot! Do not cover and the more air it gets the better both through and blowing on it. Is a game changer if you know what you are doing

I have been using these ozone generators for many years and they work well. The only issue I have is the cleaning should be easier. Maybe instead of those 4 small screws it could be hinged so maybe a clip or just one screw could open it because although I can do it with little trouble, I can see some people having a problem and they do need cleaning almost monthly as the tiny "pipes" clog up. Sometimes you can just insert a small drill without contacting the membrane behind it to unclog it. But eventually you must remove that end piece to do a more thorough cleaning. It is difficult to position those small screws while keeping the "O" ring centered. I am an inventor and could make it much more user friendlier.

I have a 75 gallon saltwater tank. This ozone generator is amazing in just three hours at the low setting number three. My water is now crystal. Clear the clearest I’ve ever seen it. Unbelievable I highly recommend it.

I was so happy when I found this device, and it worked so well initially. After 75 days of use, the device stopped producing Ozone. Cleaning according to the provided instructions didn't help. The worst part is the finger-pointing support. The manufacturer points support back to Amazon, and Amazon points support back to the manufacturer. When it worked, it was great and low-cost. I would be OK with replacing the product every three years of so but every three months is ridiculous!

Works well for all potential uses

I think the best description I can say is WOW that thing is amazing I have a 75 gallon reef tank I ran it for about 1 hour just using a air stone nothing fancy, you could just look at the tank see it clearing it was sparkling clear water 1 hour seems to be good with out over doing it I had it set about #4, I would definitely buy again. also you wouldn't need to use it every day

Does the exact same thing as the big expensive units! Worth every penny.

Cumple con las expectativas el manual viene muy escueto es importante detallar más adecuadamente temas como calibracion y forma de uso

Kein Normsrecker für Deutschland man braucht einen Adapter. Beim anschließen sofort durchgebrannt.
