adding water due to evaporation

[C.B. Anderson]

what does everyone do when adding water back to tank after it has evaporated some....do you simply use ULTIMATE or other additives too?...still in process of seasoning tank.  Parameters staying fairly steady  I will only be adding a little less than 1 gal

also, I have not been doing water changes because all parameters stay so good....fish are happy and water is clear...it is a 55 gal. has been set up for about 7 weeks and only has 5 adult fish (mollies and platies) and 2 chinese algea eaters and about 10 babies from the mollies that are still very little so I dont think the load is high...and I am very careful when I feed to make sure they eat it all pretty quickly and only do that 3 times a day...so I think Im ok without water changes...I dont want to upset things ...if it aint broke dont fix it....is that correct assumptions?

I fill up a 5 gallon bucket with tap water and then add one ml of prime to it. Then I take water from that and add it to any tanks that are low on water. I also have a 55g tank and don't do real water changes. just top off and do a very light gravel vac every other month. Never added more than a gallon at a time.

You could also let the water sit for a day and most of the chlorine will evaporate out or you could go buy unchlorinated water from the store.

If your tap water has chloramine you'll need to use a water conditioner, it doesn't really evaporate out easily.
