my 3 platys started showing signs of ich after i stupidly bought 4 more platys and didnt qt. things went down hill, i took the 4 back. my 3 started glancing, flashing, being aggressive,staying at top, and being lathargic. i started api quick cure 4 days ago, got temp to 87 last night. this morn the behavior was the same. jaysee let me know this could really deplete oxygen levels. we have a machine that produces oxygen rich oxygen for wife that she never needs. i hooked it into my 4 airstones. the difference was like night and day and came within minutes. now theres no glancing, flashing, aggression and other symptoms. theyre back to sucking rocks and decos being happy again. historically when i feel like patting myself on the back for saving the world, i find i missed important details. does anyone have reasons why i shouldnt be doing this? i know its a bandaid covering the real problems. how long should i keep giving meds and heat? thanks for your opinions. btw i change lots of water.also they have richer colors now
