My daughter has a 1 gallon tank. Not heated, she keeps the light on 24 hours a day. It stays warmer in her room than anywhere else in the house. No filter, she does have one of those bubble things. I know for a fact the last time the tank was cleaned was 1 month ago. (I did it!) She adds water to the tanks when ever the water gets low. Now, on friday I cleaned all my tanks and decided to do hers too. Was curious about the water so did a quick test with the strips that I bought. The test strips said that everything was just fine!!!? There wasn't really much difference at all from my tanks water and her tanks water. My two smaller tanks 2 gallon & 2 1/2 gallon, I do a 50% water change on Mondays and 100% on Fridays. The two 5 gallons I do on Fridays 50% and every other week 100%. Why no difference? Are these test strips junk? They did show some difference in a couple of my tanks and I knew to do a water change. They are Jungle Quick Dip 5-n-1 test kit
. They check pH, nitrate, nitrite, hardness, alkalinity.
This is Bonnie....She looks really good to me.
