Water parameter question
My test yesterday were:
am - 0 nitrite - 0 nitrate - 0 ph - 8.2 alk - 14 calc - 400 temp - 81 I'm using the Sera tests, and a pinpoint ph monitor. Is the alk a little high? How do I lower it without messing up the ph?

i wouls say the alk is a little high,i would maybe do a water cganche them just let it come down on its own,while keeping an eye on the rest of the parameters to make sure they stay within range.just my thoughts

What salt mix are you using. Also, are you dosing any alkalinity supplements or buffers? Stop supplementing if you are and either do a water change or let it fall on its own.

Your alk is alittle high yes but if your inhabitants like it
they are in jepardy yet and it will go down if you don't add any more buffer. I know instant ocean will mix out @ 12+- dkh @ .024 salinity So you are not that far off. Pin point are very reliable But I wonder did you calibrate before insertion??? |

Calibration? What's that?
Yes I calibrated the pinpoint. I'm using RedSea Coral Pro. I was using Kent buffer to bring up the ph but I stopped last week. My ph was below 7. seems to have stablized though.

No typo. That was shortly after initial fill up of tank, amm, nitrates, nitrites were all off the chart at the time. I was at about 7.5 when I started adding the buffer.

What kind of salt are you using? a ph of salt water under 7 just seems way off the scale to me, especially now that it is at 8.2, was this in fact salt water that tested below 7?
regardless a couple of articles for you to read, especially take note of the elevated co2 level section of the first article, and test that out. To balance the calcium and alkalinity, you will want to supplement calcium, but not alkalinity, this situation is covered in the second article. Low ph causes and cures Solving calcium and alkalinity problems I still am stumped that you are saying your ph was below 7.. regardless it is at 8.2 now, in range where you want it.. however that alk is a bit high, steps are needed to keep the ph in this general area., and gradually lower that alk. Over time calcifying organisms will lower the alkalinity (as well as ca) and it will drop on its own, but in a new tank these are limited (coralline, and perhaps tube worms). Make a fresh batch of salt water and test the alk, and the calcium levels of the freshly made water, perhaps water changes will help some, but as covered in the saecond article linked we want to gradually lower the alk, while supplementing/maintaining the ca. Once these are in line, then we can see how that ph is doing without the elevated/overbuffed alk reading, and go from there. read those articles, and take things slowly.. if you have any more questions ask! |
