A used one with a probe will run you about 1500 USD on ebay. I have no idea the cost new. You would have to contact YSI and ask them about a 556 to get the price on a new one. They aren't published.

Is that correct your ORP is only 79.9 or is it some other scale used. I'd freak if mine got below 200.I check it with a YSI every other water change. Not that I care but it's a number it spits out at me.
You folks have got to get one of these things.

It's different. I can't recall the difference though.

I lied. I misremembered. It's not different. ORP values fluctuate heavily. I have to check ORP with that probe in the tank to get accurate numbers. If I pull a sample and let it sit out on the counter for a few minutes then test it will always come back with skewed ORP values.
That's not the meters fault. It's because the ORP drops fast without circulation. I won't answer questions while half asleep ever again.

At work I check every other day with a Hach LDO10105. I feel like once a trend is established this is mostly busy work. The DO% don't change more than 2% from day to day if all my equipment stays functioning and I am not changing stock. Personal opinion: degass tower is the best way to go if you are concerned about over or under saturation. On our 1600gl coral exhibit we had to install a degass tower to bring the DO% down.

Surface agitation has always been a neat tool. It further stabilizes PH. In some situations maybe not all, but for the most part the efficient gas exchange of surface agitation is great to combat the acidity the CO2 produces.

I had the Neptune PM3/DO kit for a while and found it mostly useless. A major pain to keep the probe directionally accurate. Even when it was, there was never any practical way to intervene that wasn’t already being done. Properly circulated tank and an overflow/sump takes care of it. I feel the same way about DO as ORP …..

Unfortunately it looks like that model has been discontinued. The only model YSI sells now is 2,000 big ones But now I want a digital parameter reader too.

what did you use for CO2 absorption and what do you use to dose H2O2?

Just regular CO2 absorber granulate with indicator. A German brand which i doubt is available in the USA but you can use any. I directed the air through the absorber into the air stone.
I am dosing the H2O2 with a diy dosing pump. It works differently than normal dosers because it is set up to dose one drop each 3- 10 minutes (adjustable). Since then my ph increased to 8.6 so i guess this method of adding O2 is a bit too effizient.

I wander if there is a correlation between reefers that have been in the hobby 15+ years and those that consider dissolved oxygen in their systems.? Don’t hear about it much now but it used to be a matter of importance in the old texts.Aquatic air: Do you pay attention to dissolved oxygen in your reef?
Oxygenation is important to your reef tank for many reasons including aiding in respiration, the decomposition process, stress reduction, overall health, growth, and much more. There are many ways that oxygen can be added to the water such as surface agitation, aeration, filtration, flow, and surface skimming. Whether using DO (dissolved oxygen) meters to test water oxygen or using another indirect method, some reef keepers have found that paying attention to dissolved oxygen in a reef tank can be helpful. Others simply look for stagnant surface areas or dead zones where detritus collects and there is minimal flow. Please tell us if you pay attention to dissolved oxygen in your tank.
Pro Tip: One often overlooked area of low or no flow can be the sump. In addition to potentially low oxygenation, detritus can collect in these areas and create other challenges with water parameters and add stress to your reef.

FWIW, those assuming their tanks have good gas exchange might look to the pH change day to night,. With perfect gas exchange, pH would not move (or move only in relation to changes in the air, such as people vs no people in the room with the aquarium).

I also have a sump in the attic, and garage, and have been thinking about this too. How did you decide to address this?
