will a 48 inch fluval 3.0 be enough to be low to med light on a 75 gallon tank. I have the light on my 55 gallon but wanna upgrade to a 75 gallon or will i need to lights for low to med light plants on the 75 gallon?
best thing you can do is keep your ammonia and nitrite and 0. if you have to do daily water changes to maintain 0 ammonia and 0 nitrite then do water changes everyday til you system balances out.
Its hard to tell. Just keep the water clean and the fins should grow back with time. You could treat with an anti bacterial to help prevent infection. not sure which meds are available to you.
