How to do clean water which fill in aquarium if doesn't have water conditioner?

Hello, I bought 3 fish (2 cichlids and 1 ray) and an aquarium (90 litres) yesterday. I prepared the aquarium and put the fish inside. However there is a power shortage at the moment. The temperature of the water is fine but what can I do to increase the oxygen level?

how do I change the ammonia, nitrates in my aquiarium

I have a 20 gallon tank. I'm thinking of buying +5 fish. Which fish could I buy and what would I need for the fish and tank?

Two of the fish fins are clamping down close to their body. I did 75% water change and hopefully they will get better. I do not have the water testing kit. Will buy soon. Is there any ways to get them better? I could see some of their scales are off. They sometimes don’t swim, they just stay there and let the water flow move them. I’m getting air stone soon. Do I need VERY strong filter for them? (It’s little filter) two of them is sometimes going up to surface?

We are new to having aquariums, we really didn't realize so many things played a factor with the water. We currently have a 10 gallon tank but want to increase to a 29 gallon tank. We currently buy gallons of water but with the 29 gallon tank we really don't want to have to do that. We have well water with a salt filter. My levels from to tap was nitrate 10, nitrite 0, hardness 0, chlorine 0, alk 100, ph 7.. is my tap water safe even with the salt filter.

Going to be bringing a few guppies home, probably all females for simplicity sake. We have the 10 gallon tank, master test kit, heater, filter, some Omega One guppy food, and the proper decorations. But I would like to know any tips on how to safely bring them home in my car. (We still have to cycle the tank, so no rush.) We will be getting them from an actual pet store, definitely no Walmart or Meijer fish as those tend to be much less healthy.
