Hey everyone,

So I went outta town for a couple weeks and left my roommates in charge of my tank. I just came back and all my parameters are messed up! I'm new to this hobby and don't know what my best options would be, hopefully you guys can help me get this under control and give me some suggestions, h2o change? chems? new fluval media? etc

My parameters:
Spec. Grav. - 1.026
Ammonia - 0.25ppm
Nitrate - 50ppm
Nitrite - 0.2ppm
pH - 8.0
Alk - 3.0
Phosphate - 0.05ppm
Calcium - 550

My tank:
Its a 33 gallon, I do 7gl water changes bi-weekly. Feed once daily. Have a Fluval 205, CPR BakPak, Korali powerhead.

Please someone help me out I wanna get this all perfect. Thanks!
