Hi, I was doing my daily routine of checking my tanks and I noticed in my planted 20H, my fish were flashing, so I checked my parameters, ph 7.4, ammo.25, trites.25, and trates 0-5.0..so I immediately did a 50% PWC waited over 1 hour retest, test fine now but I still did another PWC....while soing so, I noticed against my glass ity bity white stuff ....it can make tank glass look dirty...so I rubbed it off and tried siphoning it out too....what is the most common reason and the easiest treatment?
