Hi Guys,
Just woke up this morning and found this white spot on 2 of my female guppy's. Have a 65 Gallon tank with 12 guppies and 4 Bolivian rams. Temperature of tank is 25C/77F
Ammonia 0, Nitrites 0 Nitrates being constantly 10 for a while. Soft water and PH being steady at 8.0
Did a 50% water change 2 days ago trying to get rid of the brown hair algae.
