in a sealed room you need an air scrubber not sure y but i remember u do i prefer charcoal theres a inexpensive thread for making one on here somewher like 30$ or something


i just relized that you said querkle, i just started using FFOF in place of my normal cause i found a spot to get it cheap but i dont really care for it cause i tend to have probs 2-3 months in, works great at first tho. to the point. my purple erkle does the same shit in ff just about 2weeks ago now. i added some magical to her only, and it seemed to stop the spread.

dont try to fix whats not broke i think your prob might be the strain since my erk does the same thing in the same medium. try to add a lil cal mag not full strentgh, while reducing your overall strength

do you feed with every watering?

maybe rusty will chime in here

water softener like a filter or something
