I know this is a saltwater forum, but I thought someone could help me .
I have well water that tests 6.4 out of the tap. It's not hard. (the fish store said it's about mid range for hardness.)
My problem is that the next day this water will test 8.0! (using the API high pH tester.) This is the water in the aquarium and in a glass of water just sitting on my counter. What would cause such a fluctuation in water pH???
I have just started a 15 gal tank over a week ago. I have a bog log and 5 zebra danios and a few plastic plants. My filter is an outside Aquaeon for up to 30 gal.
Ammonia is on the yellow side of .25 ppm. Nitrates and nitrites are 0.
Do I need to do water changes yet? And when I do start changing water, do I use it right out of the tap at 6.4, or let it sit in a bucket for a day or two until it reaches the 8.0 mark?
I bought this for a tetra and 1 male betta tank. Will I ever be able to get the pH down to an acceptable level for them? Maybe I need to buy water? I hate to even think about toting 5 gallon jugs of water home from the grocery store!
Any advice will be eagerly awaited!
