i have a 6.2 pH in my 55 gal.fresh water fish tank. help me?

m c asked:

how can i raise the pH. my tester also says i have very hard water. what does this mean, and how can i fix it.
i have had a really good set up, until the ike hurricane, gave us no power for 5 days. now i cant get it right.

i have several large gold fish and bala fish, along with a large cat fish algae eater and peacock eel

my levels are…..
NO3–250
NO2–1
HARDNESS(GH)–280 very hard
KH–180
pH–6.2
i own a TETRA test easy strips–5-1 test.
what is of normal and how can i fix it. and keep it good.

whats weird is my water has a pH of
7.6, and i change 5 gals and it will change my pH, but the next to days, its low again.

    I suggest you do seveal partial water changes in a short period. (Every day) Your NO3 reading is very high, and could be causing the pH problem. NO2 should be zero, but thats probably due to the filters being affected by the power outage.

    With the power off for that time your filters (and tanks) cycle will have been damaged.

    Dont do a sudden huge water change, as a big change in pH can stress the fish more than they already are. But 25% per day will do no harm, and will not affect the recovery of your filters cycle.

    That will lower your nitrate level and gradually bring your tank water closer to your tap water measurements.

    Never be afraid to change water, it seldom makes things worse for a tank.

    Test your water from your tap. If it is a good ph then do water changes. Hope I helped!

    The water you get from your tap is more than likely buffered so will show 7.6 from the tap and then the buffer breaks down and your tank water will be reduced to the natural water table Ph, it will possibly leave residual minerals which will show up as hardness in the water, as long as the fish are looking ok i’d not be overly concerned as the fish you name can tolerate the low Ph. If possible i’d invest in a proper test kit as using chemical regents are more accurate and have a shelf life on them where as the with strips you’ve no idea how long they’ve been on the shelf or what contamination they may have suffered.
