Where do you keep your ORP probe?

[bradleyj]

For almost eight months now I have been keeping my orp probe up in my tank by the overflow, but the problem is that algea grows on it in two days, so I end up cleaning it three times a week, or I never get the correct reading for my ozone. So today after cleaning it , I decided to try leaving it in the sump so it is out of the light. Hopefully I wont have to clean it so often. I'm wondering where most of you guys keep yours.

In the sump,but bubbles tend to throw it off every couple of days. Scrub and soak and it is as good as new. Have you tried using the caliberation solution,thinking of getting according to Lou at American Marine. Here is the link

I feed ozone into my skimmer, I keep my ORP probe a few feet after where the skimmer dumps into the sump.

you could T off your return, drain, or closed loop, basically any plumbing and install a compression fitting on it. this would make a much more permanent and clean installation.

mcmaster.com has a good selection. marine depot just started carrying it also, but only in one size... i think it's 1/2".

on mcmaster it's page 775 under "Nylon Liquid-Tight Cord Grips"

these are great for installing the pH probe directly into your calcium reactor too either via the recirculation plumbing or a drilled hole directly in the reactor itself.

I thought the best place to keep an ORP meter would be in the actual tank itself.

The whole purpose of the ORP is to read the properties of how clean the water is inside the main tank; as the main tank begins to become saturated with inorganics this pollutes the water.

The ORP probe then detects this and relays the message down to the meter that the ORP is dropping below the set point of where you would like the quality of water to be say 360 mv.

As the probe indicates a drop in ORP the meter if it's a controller will turn on the Ozone to inject into the skimmer.

As this process takes place the inorganics that were polluting your main tank are being eliminated via ozone, end result is ORP climbing back up to acceptable water quality and the the controller shuts off the ozone.

The ozone will not fire up again until this scenerio takes place again.

So, if it were me setting up Ozone which I will be doing soon, I would not place my orp in the sump but rather in the main tank.

I want to know what is going on in the maintank not the sump, the sump can run at different temps and doesn't constitute complete accuracy of your main tank.

If the ORP meter was to dectect ozone, which it doesn't from what I've read, I would most certainly place in next to were ozone is being injected; by the return line of the skimmer in the sump.

I've been reading up a lot of Ozone and this is where I'm picking up my facts; if I am incorrect about the ORP meter, someone please come in and correct me since I don't want to give out wrong information.

Just that I've never read that ORP meters detect ozone in the tank.

I've always kept them in the sump and they seems to be just fine there. Even on our 10,000 gallon system with a large ozotech unit, the probe is in the sump which is about 60 yards away.

In my A..... sorry too easy

i just moved my ORP probe from the sump to the tank last week. reading in the sump would reach my 370mv set point. however, in the tank (which is what i wanted to really measure) it has only reached 350.

I keep mine in the sump out of the light. I clean it about 1x every 7-10 days usually when I do my water change. No problems thus far.....aside from slight bleaching of some mushrooms despite the slow increase in ozone
