I recently purchased a Tetra Crescent 3 gallon kit from Meijer with the idea of keeping it as a back-up tank in case I should need it for some reason. But of course, with an empty tank sitting around, I just want to fill it and get another betta. I have cleared a space, bought decor for it, and am planning on setting it up today to get it running so that when I find the right little guy, he'll have a home waiting for him.
The last time I set up a tank (my 2.5 Aqueon Minibow), I ended up with inexplicably cloudy water. I rinsed the gravel many times, I boiled the decor and plants, I conditioned the water with Prime... I don't understand what happened. This never happened when I set up my 5 gallon, nor has it happened before in the 2.5 (It had had a crowntail in it who passed from old age, so I decided to change up the decor for my new VT).
Still, I decided to seek advice from you all on how to keep that from happening this time. I plan on rinsing the gravel at least a dozen times (if not more... until the water runs clear), boiling the roman ruins ornaments I bought, boiling the silk plants (although it tends to sort of ruin their shape... can I just rinse them in warm water?), and rinsing out the inside of the tank with plain water before I fill it. I will also rinse the filter and the filter cartridge before putting them in, as well as the heater and thermometer.
Am I missing any major things here?
