David,
From an equipment standpoint, using Ozone on a freshwater aquarium can be a bit more difficult to use. To use ozone, you need some sort of a reaction chamber to introduce generated ozone to the aquarium water. In Marine aquariums this is easily accomplished with the use of an appropriate protein skimmer in the sump of the filtration system. If you use a sump type, or wet dry type, filter on your discus tank, then you can use the same method. Even in a freshwater aquarium, a protein skimmer will still act as an efficient reaction chamber.
If this is not an option for you, then you may be better off using Chemical media, Reverse Osmosis water, and Ultraviolet Sterilization to acheive an low organic load on your system.

Thanks,
Dave

I have a 140G fresh water discus tank. I tend to go overboard in buying equipment and would appreciate your recommendation for the appropriate ozonizer system model that will meet my needs.

Thanks,

It depends on the type of algae you’re having a problem with. Ozone will oxidize dissolved organic waste, so it will help control slime algaes, and maintain overall water quality. But will not directly effect higher forms of algae established in the aquarium. I would recommend looking at Nitrate, Phosphate, and light quality and duration as a cause for the algae before installing Ozone as there may be another issue to address to fix the problem.

I have a frequent problem with unwanted algae in a reef tank an wanted to know if ozone will help. I do my 10 % water changes bi weekly with r/o & deionized wter.

For freshwater, I would reccomend keeping to the lower end of the scale for ozone use. 5mg per hour, per 100 liters. Introduced through your skimmer in the sump. With ozone use in any system, it is always smart to be conservative. Start with your unit at its lowest setting, and see how much ozone is needed to raise your ORP to the 300-350mv range. Every system is going to act differently depending upon its given organic load.
Thanks,
Dave

I have a large 800 lelitre aquarium with fresh water with discus & other fish. It has fine gravel driftwood and well planted. I have a large ozotech & controller skimmer in the sump. Could you please tell me what levels of ozone for fresh water I should use & if you have other imformation.Grant.
