I have the same unit on my 250. When I run it at 100% I can get close to 400, but rarely ever go over.

Just slowly take your time (over a couple of months) turning it up until you notice no improvement in your system.

It sounds like your system is good already.

Nice clear water though, yeh?

are you running it into your euroreef skimmer? How has your skimmate looked since putting in ozone? Are you running the output of your skimmer through charcoal?

the skimmer has black crap in the collection cup and im running it wet any ways
and yes Im running thur the air lines

I'm just hooking up the same unit and I'm wondering if you got correct readings from your probe at once or did it take awhile to break in. Mine has been in about 24 hrs and still seems way too low. (165mv)

It can take 1 -2 weeks to break in the redox probe. I would wait 2 weeks then GENTLY clean it with a toothbrush.

You can also buy small packets of test solution to see if it needs calibrating.

Thanks for the info, I'll give it a while to break-in.

Also the readings vary depending on what the set point is at. The instructions say to take the readings with the set point cranked all the way up.
I get 165 with it cranked up and 48 with set point at the lowest. This is with the selector switch in the reading position. Does that make sense?

Also, after a ton of searching I finally found a reactor for pretty cheap.
It's 22 inches tall and it looks like it comes with same shredded plastic media as the MTC.

They are drop shipped from Aquarium Life Support Systems

They don't take Canadian credit cards, just cert. checks or money orders.

I'm going to run the output through a Phosban reactor filled with carbon.

Sound like you are all sorted out. Pressurized reactors are 100% the way to go over using a skimmer. Make sure you filter your air line OUT through carbon as well.

Does your system come with an Air dryer?

Please keep us updated how this works out for you. I am interested in this as well rather than running through my skimmer..

I did get an air dryer and I'll have to figure out a carbon air filter for the exhaust when I get a better look at the reactor.

What are you using for an air pump? Is it adjustable output (like a Luft) or did you have to use a valve to adjust it?

I'm still not sure how you can pressurize the reacter and have an air exhaust.

Your MTC is an awesome piece of hardware, thanks again for the tips.

No worries, and thanks.

I do use a Luft pump to adjust pressure in the chamber actually. What happens is that as the pressure build, the air escapes from the chamber and into the Carbon filter.
