Ok here goes... 29g planted. 6 weeks old.
7 neons, 2 guppies, 5 guppy fry, 2 molies, 2 albino corys.
API MASTER TEST KIT LIQUID
for 3 weeks now everything has tested perfect...
before that the only issue I've had with chemistry was a slight nitrite problem .25
other than that chem has been great!
OK PH issue...
my tap ph is 7.6-7.8
tank has always been 7.0-7.4
Today I test and retested... WAY LOW 6.0
and it could be lower my test kit bottoms out there.
for a control i checked my tap and it was 7.6-7.8
What do I do?
Nothing in my tank has been changed or modified. The only thing I've done or added is my weekly 20-30 percent water change.
Everything appears healthy,eating,active.
The only thing I can think of is we went away for a night, I had an African Dwarf Frog. When we got back he was stuck in the filter intake. He could have been dead in the tank for 24-36 hrs, before he was removed.
Other than that I have no clue. I do have some crushed coral. Should I add that.
Should I do a big Water Change?
Thanks for any and all help!!!!
