blue, imo your ph,temp, and salinity are all low...ammonia .4 how often do you do water changes ?

pimp ha having a low temp is a good thing for me, im running the tank without the tank lid and before the weather outside got cold my temp was about 83 and that felt warm as hell, i need a buffer for my ph im guessing, salinity is low prolly because hte water evaporates so fast that i just add RO water more often than i do water changes, my last actual water change was about 2 weeks ago and i have added 5 gallons of RO water twice.... i know my levels arent where their supposed to be but you have to remember i dont have a skimmer, never added a buffer for the shitty ph, and im running my FX5 off of the filter media that came with it, i havent bought the different stuff you put in it
