Just watch closely and, yes, by all means use bottled
SPRING WATER not distilled or drinking water. It has some of the minerals and stuff the other types take out and helps the tank along. You may have to take more than 1 gallon a week out until the tank is cycled, if it is not. More like 2 gallons every other day or so. Do you have a Master
test kit for Freshwater Aquariums, not the strips? You will need one if the tank is to stay healthy. You need to keep an eye on the parameters of the water with respect to
ammonia,
nitrite, and
nitrate.
If your tank is not cycled, you need to read the following so you understand what is going to happen to your tank and readings...
http://www.fishlore.com/NitrogenCycle.htm
With fish in your tank you should not allow the levels of the above compounds to go above:
Ammonia 0.25
Nitrite 0.5
Nitrate 20
Since you already have fish in the tank, the fishless cycle will not be possible and the way to control the spikes of higher ammonia, nitrite and nitrate is to do water changes. Do a 50%
water change every time that the levels get to the above readings and they will stay below.
When your cycle is complete the readings for the tank will be:
Ammonia 0
Nitrite 0
Nitrates Less than 20
