What cause low ph and what is the implication

[News]

My tank ph had down to about 7.7 for about 1 over months and did not detected any abnormal behavior from the invertebrate or the fishes. Any advise on this issue?

hi there

wat ph tester did u use??? mayb u can get ph buffer...

I used Hanna Test Pen. Which brand of buffer to use?

Actually I want to find the root cause of this low PH.

I tested my fresh water or mixed salt water, both have PH of more than 8.3.

I tested the calcuim content and it show more than 420.

So what cause this low PH and will it has any impact on the fish and inverterbrate?

have you come across this article : Low pH causes and cures in reefkeeping... good read.

Basically, if I am not wrong, pH goes on a logarithmic scale which means that a point increase would mean a ten fold increase in reality

I remember Anthony Calfo mentioned, rather comically, that imagine you are enjoying yourself in a ###### beach and suddenly transported to the Antarctic, still ######.

Imagine how stressed your LS would be

Of course BH means very well ... Anthony Calfo says the antarctic for a good reason... he didn't say the sun.

a point increase is a 10 fold decrease in reality.

Thanks bro madmac for correcting my mistake

I was either too engrossed in the ###### beach part or too stressed in my practical today

Thanks again

Hi Bros,

I had just read up the article regarding the low ph. Yes, this is a very useful article, thanks madmac.

I just wonder whether the low Ph was caused by the final product (which claim to be carbon dioxide and water) from AZ NO3 which I had just used for a week to lower the nitrate level?

Just wonder should I use the PH buffer (still do not know which brand to use) or limewater (kalkwasser) before or after the complete cycle of the AZ NO3.

Any advise?

I dont' use azno3, so can't comment. Why don't you tell us a bit about your tank and its parameters.
