<p>YEP -- one other thing to consider --- is the it looks like you are running on battery power. So you will need to be checking your battery as your voltage will start to drop off at some point in time. This will effect your DO readings over time.

At some point you will need to replace the battery and then you will need to recalibrate the unit just as you did above. I spent $10 more and purchased the pinpoint wall wart for constant power supply source. It is very easy to hook up and runs for ever and this way I am always sure of my readings and I have learned how to determine if I am getting bogus readings (like 90F and a DO of 12) at this point I will recalibrate or get a new probe or check the battery.<br/> <br/> <cite>halemart said:</cite></p>

<p>Mart - you left out the last step in the calibration process. Once you get to the 20.9 reading you need to move the DO switch from CAL to DO. Then put it in your tank. Doing it the way you are doing it you are still in the calibration mode, so you are in constant calibration and nothing will be held at the constant calibration point this way. Once you move the switch back to DO mode your are ready for the tank and you will get correct readings. As for the fluid, the pinpoint people are…</p>

Once you move the switch back to DO mode your are ready for the tank and you will get correct readings. As for the fluid, the pinpoint people are going to tell you to leave it in. Which is ok, I have have found that over time the solution comes out and is replaced by tank water anyway. Once you start to see the correlation between your water temp and aeration of the tank you can go with tank water and see if you experience any difference in reading. I did not, but for your own piece of mind you should follow the manufactures instructions from the get-go.</p>

<p>I remove the electrolyte and rinse with distilled H2O a couple of times. Then I fill with tank water and install. I do not know what they use in the electrolyte solution. I have a rule that I never put anything into my tank without knowing if it will harm the fish.

<p>I remove the electrolyte and rinse with distilled H2O a couple of times. Then I fill with tank water and install. I do not know what they use in the electrolyte solution. I have a rule that I never put anything into my tank without knowing if it will harm the fish. If there is a question I always have a backup tank with goldfish that I can test before going in to my good tanks. As for the caps I have never replaced them and I get good readings for about 9 months. When my reading start to get weird readings such as a reading of 6 when the temp is cold and I have lots of water exchanges. I will recalibrate and if does not fix the problem and I am around the 9 month time frame I change out the probe. After a little while you will have a good feel for what your reading should be and the reading for me just confirm that I am good on DO. Your fish will also give you a good indication of DO levels. As you start to gain an insight as to your readings make sure you watch the fish so you observe their behavior at the different levels and how they are acting. Soon you will get very good at just looking at the fish and know if you have a problem. Sometimes meters mess-up and for me they are just a gauge and a tool to understand my tank environment better.</p> Ok, after I calibrate do I le…tag:aquaponicgardening.ning.com,2011-11-16:4778851:Comment:2508802011-11-16T21:05:33.000Zhalemarthttps://aquaponicgardening.ning.com/profile/halemart
<p>Ok, after I calibrate do I leave the electrolyte in? So, caps each last about 9 months then replacement cost is about 20$ not as bad as I thought, I thought one would have to replace the probe after 9 months.</p>

<p>As to your questions:</p>
<p> </p>
<p>Calibration is a little tricky at first as you need to fill the cap with solution to calibrate and moving the switches back and forth.</p>
<p> </p>
<p>As for caps do a google search on the following and you will have lots of options for them:</p>

This time of year I can go as high as 20, night time temps are around 45F in a 100 gallon tank. I run 24hours with two beds with E&F - 5 mins to fill and about 10 to drain. With day time temps in the 60's I will run readings around 12-14. In summer day time temp can get upto around 90F my DO will be down around 7-8. At night time I will see readings around 10-11. I once hit 4 and started losing shubunkin's, in this case my electric shut off and I lost my cycle effect and the backup air pump.</p> Thanks Rupert, ya I have been…tag:aquaponicgardening.ning.com,2011-11-16:4778851:Comment:2507302011-11-16T10:53:38.933Zhalemarthttps://aquaponicgardening.ning.com/profile/halemart

I did a google search and someone was in the opinion that Talipa are better off with 4.0 for DO, they said higher than that it was more than they really needed. I am surprised at the readings myself, I was thinking it would be the other way around. I think I will take a visit to my local lake and see what the DO level in the lake is.</p>
