Can anyone tell me, loosely, how much ammonia to add to a 75 gallon tank. I know that the amounts vary and the general reading should be 4-5ppm, I just need to know a quantity to start with.
When I did my 55 gallon I used the Ace brand ammonia. It believe it was 10% strength.

I dosed 5ml (used a test tube from API test kit as measuring device) and it brought ammonia up to around 5ppm.
