Bros,
I have recently started keeping Ranchu but it seems that I am always facing high ammonia despite me changing the water daily (20%). I have set up the tank for 3 weeks but still facing ammonia issue despite me adding API Quick Start solution 3 times a week.
Ranchus began to develop black stain on fins and I believe it is due to ammonia burn. Any advise?
This is my setup:
60cm x 38cm x 30cm tank
T5 lighting - Turn on for 8 hrs/day
Eden 501 Canister filter
Colourful UV Filter (UVF-5W) - only turned on for 8 hrs/day
Fauna
3 x Cory (From previous setup)
1 x Guppy (From previous setup)
5 x Ranchu (avg 3")
