Freshwater Aquarium/High PH in freshwater tank


Hello...I have a 49gal freshwater tank and while I was away for a few weeks, my husband decided that the ph was to low so he added baking soda to my tank, the ph is now at 8.2. Am I correct in my thinking that I need to change 5 to 10 gal. every other day to get this to lower. I had to stop him from putting battery acid in my tank to lower it. I have a R.O. system and that is the only water I use. Please advise, I don't want my fish to become little corpses.

Without know what types of fish are in the tank, it is hard to tell if the ph is too high. Usually, Ph is not as serious as ammonia or nitrites. Fish do become accustomed to Ph levels. Please NO BATTERY ACID. I almost fell off my chair when I read that. You can either lower the Ph by doing the water changes or by using a product called Ph down. API make a great product that I hear works very well. Let me know what types of fish are in your tank.

I can answer question regarding, raising, breeding, feeding and the general upkeep of Betta fish. I can answer general questions about isolating a disease and the treatment needed to help your Betta. I am knowledgeable in fresh water tanks and can answer any question regarding them. I cannot answer questions about salt water tanks.


I have had fresh water aquariums for most of my life, including the 23 years I served in the Marine Corps. I have been raising Betta's for some time now, and have ventured into breeding a few years back. I currently own 5 males and 4 females and I have about 200 almost 3 week old fry. I make my own filters and I have tried almost all the food on the market for fry and I know what has worked for me and what has not worked.

I do not have Betta related educational credentials, but I have educated myself in Betta care. I have read quite a few books and articles from both the internet and ones that I have purchased. I consider myself well educated in Betta care.
