I'm so scared for my fish, I test my water once a week which after reading around here I realized I should actually be doing every other day and shouldnt use the strips because they are unreliable so I'm gonna get the master test kit one but anyways, on Monday, because I tested my water with the strip and the nitrates were 200ppm and nitrites are 10ppm in my 5 gallon betta tank and my pH wouldn't go up past 6.0 I've been adding the neutral regulator everyday like it says on the label to try and get it to 7 but I won't budge. Also my ammonia level is way too high like between 2.0-4.0 I've been adding ammo lock every other day 2.5 ml pet smart had me do a 50% water change on Monday and come back Wednesday. So I went back Wednesday and everything was pretty much the same they said to do another 50% water change but replace the water with spring water and now today (Friday) the nitrates are down to 80ppm and ammonia is down just slightly but nitrites and pH are still the same. I changed my filter Monday because it was time to do it anyways could that be what caused this? It was really dirty. Oh and I'm only feeding him every other day and I did very thorough gravel vacs every time I did the water changes. I've had this tank for about 6 months. I was afraid I took out a lot of the good bacteria so I added some tetra safe start I added 2.5 ml. Should I do another water change today?
