Not running skimmer

[joseserrano]

I thought most people including BRS recommend to run CaRX at 6.5. I do use a second chamber.

You can run media I think as high as 7.2 and low as 6.3? Many long discussion on how it why to do either end. Must note, not all media is rated for the lower end. You can turn it into slush

Thanks I’ve been running Two Little Fishies Reborn at 6.5. So far no slush

Do it bro…you won’t regret. Set and forget. Don’t have to worry about refilling your dosing containers and get the mags in too.

I personally don’t run a skimmer and do once weekly water changes as well on my 120 (20 gallons). Corals are doing great but the way I stabilize my pH, is I dose soda ash strictly at night and calcium during the day. The results without even using kalkwasser or running a secondary light in the sump for a refugium works for me. Keep in mind running my doser when the main display lights are off I have it dose on average 4ml every hour for 12 hours until the lights come on. My pH doesn’t fall below 8.1 and raises to about 8.4 when the lights come on. I highly suggest finding out what your net alk take up is from the coral for a 24 hour period and that could potentially help dial it in for you.

Strongly disagree

You can disagree to the truth all you want. Doesn’t make it untrue. That’s leftist thinking.

Haha. Yes, I’m sure because of your age you know everything to a degree no one is capable of understanding. Also hurling labels is not very mature of you.

I’ll check my probes again but I don’t think they’re wrong as this is untenable. Assume that my ph is over estimating my ph. Since I switched the dt and CRx probes and verified that they are consistent (meaning they are either right are consistent wrong because when switched one would record what the other was recording and vice Versa). If they are over estimating then my CRx is not 6.5 but must be lower then my dt ph cannot go high and my media would be mush and my Alk would by sky high not the recorded 8.5 by Hannah. See the logic …

So you're cross checking them to make sure they read the same number each time? Not saying you're doing anything wrong but want to make sure you're calibrating your CARX probe with different solutions than your DT probe. So when you swap CARX to DT it should give a different reading than your DT probe.

Usually calibration for DT: is fluids 7 for low and 10 for high for accuracy around 8
CARX: would be 4 for low and 7 for high for accuracy in the 6 range.

I'm sure you good but just wanted to make sure. I ran TLF around 6.65. I did have to drop down to 6.4's for ARM xtra course.

Yes. I cross checked them. So when I put the CRx probe in CRx it read around 6.5 and the DT probe read 8.15 to 8.5 depending on the time of the day and light intensity. When I switched probes I get the exact reverse readings. I do have calibration solutions for pH 10, 7 and 4. I would like to calibrate the CRx probe with the 4 and 7 but I couldn’t do with the Apex. If you know please show me. I am familiar with ph calibration having done this many times in biochemistry lab.

But lets assume that my probes are not calibrated correctly. Obviously, they are not underestimating the true pH reasons so let’s assume they are over estimating the reasons. For example, let’s assume that my CaRX pH probe is over estimating by 0.3 then my CRx ph measinf 6.5 when it is in fact 6.2. I would expect my media to be melted with higher eluent Alk concentration and lower pH. The result of this is that my tank pH would be driven downwards not upward to a range of 8.15 - 8.5. My media would melt quickly. My Alk readings would gradually rise not stay stable at 8.5 the past 3 months since I started CaRX. For this line of reasoning I don’t think my probes are off.

Keep I mine that calibrating ph probe with solutions 7 - 10 does not necessarily put a measurement of 6.5 grossly off.

For this line of reasoning I don’t think my probes are off.

Since a few people have expressed their concern for my pH readings. I went back and recalibrated my ph probes using pH 7.00 and 10.00 (Atlas Scientific, Amazon) for my DT probe and pH 4.00 and 7.00 for my CRx probe. This was done at 12:00 with lights off for past 3 hrs) After calibrating at midnight my DT pH went from 8.16 to 8.06 (change of by -0.1) and my CRx went from 6.49 to 6.41 (change of -0.08). I think it is still consistent as my pH pH alarm often goes off when my DT ph goes up to 8.6 so it would have been 8.5. I have lowered the regulator on my carbon doser to give a smaller size bubble and keep the bubble still at 1 every 10 seconds to reduce wear and tear on my carbon doser.

sounds like you figured it out but when calibrating the ph probe I believe you select which standard you will be using, hit select then place the probe in solution, swirl and let soak until the number settles.

 

[djrice69]

it’s not to hard if you have some sort of controller to monitor the ph and alk for fine adjustments. I could help you set it up if you ever decide to get one.

One day I’ll setup a calcium reactor I’ve always wanted to but the setup looks too complicated for my simple mind lol they are making new calcium reactors more user and setup easier for simpleton like myself but I still wait a little longer

Yes Matt I can’t believe it’s so easy but I think it didn’t really make a difference. I think to calibrate more accurately I should’ve left those standard bottles in the ram water to get the temp up to tank temp so the calibration would be more accurate. I fit it at midnight so was not into waiting another 20-30 minutes.
