I have no idea what I'm doing, I guess trying to introduce myself. I just started keeping fish (again) about 6 months ago. I'm a freshwater fish-keeper. I have a 37 gallon tank which is almost cycled, two 20 gallon tanks - a long and an high (the long is cycled and the high is almost cycled,) two 10 gallon tanks fully cycled, a 1 gallon tank fully cycled, two 5 gallon tanks (fully cycled), and a 3.5 gallon tank that is almost cycled. The cycled tanks contain very easy fish like Tetras, Danios, Betta, White Cloud Mountain Minnows, and various nerite snails and shrimp I believe a couple of my shrimp are caridina (surprised they have lived in my water), but the rest are cherry shrimp. One is very long and dark and I have no idea what kind. Plus Cory cats in three tanks. All tanks are planted with easy plants and all the plants and fish and shrimp are doing well. I'm 73 years old and live on a hobby farm with quite a few dogs, cats, chickens and a beautiful black Thoroughbred horse. I have a question, but don't know where/how to ask it. It's about my well water which is totally unsuitable for freshwater fish in my opinion - GH 0, KH over 375.9, and pH over 8.8. I'm buying/using water that I buy at a health food store that has good parameters for my type of fish. This is getting very cumbersome, inconvenient, and expensive. I'm probably buying 40 gallons a month. I have an empty 75 gallon tank and can't imagine putting water in it in the manner I've been using. So, being new, I'm not sure what to do next. I welcome anyone critiquing this post and telling me what I've left out or how to proceed.
