Aquarium Advice Newbie
I maintain a 200 gallon freshwater aquarium and am running into an odd situation. It is a well established tank (over 5 years). I did a cleaning and 25% water change this past Friday. I did it the same way I always have and have never had any issues. Saturday evening I checked water quality levels everything was perfect except Ph. it was at 6.0 so I added some Ph up to raise it. Checked it on Sunday it was at 7.8 (where I like it keep it) On Monday checked again it was back to 6.4. Left the tank alone to let everything balance out and see what it was going to do. Today checked it and it is at 7.4 I have had aquariums for 10 years and have never ran into anything like this and really not sure what to do. The fish are acting normal so should I be concerned with Ph fluctuations this drastic?
Also I checked with multiple Ph testers. The aquarium is located at a veterinarian office so I used their machine for checking Ph in urine to verify my tester is accurate.
Thanks in advance for any advice
