So, I hadn't tested my water in awhile, and decided I needed to because I am getting a new betta in about a week from AB, and I want her transition to be as smooth as possible- seeing as how she is coming from Thailand, and I do not want to kill her during acclimation.
Problem... The tank I was going to put her in (a 10 gallon) has 5 other small fish who are acting a bit "draggy"... so I got a test strip.
My PH is 8.4 and my Alkalinity is 300 (high). The water is soft at 75. I use treated tap water. I tested plain tap water, and it is the same PH and hardness, so I know this is just the way my tap water is.
Then, I tested bottled water (Poland Spring) and it seems to be within the recommended range for bettas for all the parameters. The PH is neutral 6.8 and the Alkalinity is low 40. The water is very soft at 0.
So, I was thinking of just using bottled water for her. She will be in a 3 gallon tank for now, until I can figure this out.
And my other poor fish are living with high PH, so I need to lower it but PH Down has not worked for me in the past (perhaps due to the high alkalinity) but I could not find how to change the alkalinity on google. It is not due to overfeeding, lack of water changes, or overstocking because it is just how my water naturally is.
Can anyone advise me if you think bottled water is ok for my new female on the way? It is not distilled, so should have some minerals in it, I believe.
Also, can anyone recommend how to safely and slowly change the alkalinity and PH in the water for my current tanks?
Thanks for the help!
