My PH is 8.0 But my dK is close to 380 mg/l (21.0 dHK) and my calcium was < 300ppm I have corrected the calcium.. but I have no idea how to bring down the dHK.. Dose anyone know how to bring this parameter down?? without causing a huge PH issue??
I have heard the Carbonated soda will drop the dHK.. But wont that effect the PH as well??


Tank Info
125G FOWLR tank & a 15g nano.. on the same system!
PH 8.0
dHK: 21.0
Calcium: 450ppm Was under 300PPM but adjusted!
I haven't tested the rest in ages..
What started me on this wonderful adventure, I bought a Neptune apex and i have been trying to Get my PH to 8.3 using eight.four from aquavitro (Seachem) And Balance, Witch is meant to bring up the PH without effecting the dKH... But When i get it to 8.3, it drops right back down to 7.5-8.0 overnight! is there anything im missing here???

Thanks for the help guys~!!

first things first sit back and take a slow look at what your doing your trying to correct things with a quick answer sometimes its easier to just go slow and fix problems slowly.

i wouldnt worry about your ph tooo much 8.0 isnt that bad and its expected to drop and fluctuate threoughout the night.so trying to keep it stable is sometimes a losing battle and to be honest not many people worry to muich as long as your not constantly in the high or low its when you add things to correct it thats when youll get problems all that stuff you add has to have some effect on your systems balance.

is your system already fully stocked???? i would think about doing some large water changes to get your levels corrected out with the wrong water params and in with the new.

how did you raise your calcium??
