<p><br/> Scott, I misplaced the first cap shortly after purchase and began using the second. We found the misplaced one soon after and following my son's suggestion soaked it in hard contact lens solution, rinsed thoroughly and stored it in a vial filled with the solution it came with. About 20 months later now, I just checked and they both look good as new to me. Unlike the pH and ORP probes, I don't think the O2 probe is as sensitive to scratches but it should be kept from drying out by keeping it in solution when not sampling. And I think a gentle soft bristle brushing when calibration or reaction seems slow is effective in preventing scale build up.</p>

<p>Kristine, I use the 5ft. cable and try to sample with the probe tip close to mid stream and at mid depth.</p>
<p>Over all our system has about 1600 gallons with about 1200 in constant AP circulation and the rest is in sub systems like Quarantine, Top off/collection/purification/mineralization/conditioning, and I raise some feeder fish, aquatic plants, insects, algae, and duckweed, in what I call an active bog system, all separated from the main system by a wicking bed arraignment.<br></br> …<br></br></p>

<p>The Pro20 DO Meter - but, Pentair has a couple of other brands that are a lot less $$ - I suspect the YSI line is more instrument than we need.</p>
