Alright, whole story:
Sister bought a 1.77 gallon tank, put 3 fish in it. (don't hate, she's a newbie, lol) I thought it looked crampy in there, but she liked the tank because it matched the colors of her room etc. Anyway, we went to petsmart to ask the guy there to test our water. Mine was perfect ammonia/nitrates wise (ph was a bit high) but my sisters levels were getting too high (everything bad was above stress) so we bought her the same tank I got (http://www.petsmart.com/product/inde...uctId=11459461
Yesterday after work i took her water sample to be tested again, it was MUCH better, but things were a little high. (we had run out of the Safe Start type chemical that came with her other tank) He said to add that in to help speed the cycle up, and it might even instant cycle after a week or so because it's a smallish tank. He suggested to get some test strips to test the water everday because the PH levels and stuff are gonna spike and lower a lot.
I got home and tested my betta's water again, it seems ok, though the PH and hardness is around 7 (same as last time), which the guy at Petsmart said is probably because I used Springwater instead of soft tap water.
Anyway, I put 15mL of safe Start in my tank for a small boost, then put the rest in hers like the guy said. (I was a bit iffy about putting the whole bottle in there but I looked around online and apparently it's fine) Gonna test water again later, but her fish seem to be pretty relaxed, except maybe the Tetra who spazzes out here and there. Guy at Petsmart said if the Nitrates/trites get too high, to do a 20% water change. (instead of 50% because it will kill too much of the bacteria from the safestart, and put too much stress on the fish)
Oh, the filter is making way too much of an underwater current towards the bottom of the tank for my betta, what do I do? D; she's getting tossed around down there :C
