Hello all,So I am looking for some advice. But first a little back story, I have a 10g high tech tank that has been setup since December 10th, The last month or so I have noticed a increase in hair/thread algae, I tested my water and noticed my kh was a degree higher causing my pH to be slightly higher and thus my CO2 levels were lower. I decided to start rematerializing my distilled water instead of mixing with tap. But just received the 3 salts required to do this earlier this week. Those salts are MgSO4, CaSO4, and K2CO3. Now onto the problem...Last night around 5pm, I re-mineralized my distilled water for the first time with MgSO4, CaSO4, K2CO3. I use a bucket to reheat this water, and have a powerhead pushing the water, which is then covered with a lid. This morning around 5:45am I had some extra time before leaving for work and decided to test the parameters of this water. The kh was 3, and the gh was 7, and this is what I was targeting for my water but when I tested the pH it was reading at 8.8 or above. I was just using the API master kit. I was not expecting the pH to be that high. I have a pH pocket meter that I will check with later this evening.I am kinda lost on how the result of the pH was so high. Does the water need more time to mix the salts in? Could the test kit be bad before its expiration date? Any suggestions or thoughts would be much appreciated.
