How much is too little ozone for my system?

[ryanuy]

Hi!

I have a 700g tank and 400g sump with a total system of around 1100gallons. I am currently using the Ozotech 220 plugged into an extra skimmer. I was wondering if this was enough ozone for my size of tank or should i spring for the bigger model which is the Ozotech Poseidon 400?

Thanks!

Sounds like you should go for a bigger unit. I ran a 200 a 300 gallon system and used it about 80%.

Is there anyone else still using ozone? Just wondering about your system size and how much ozone you use and how often?
