when i was cycling with fish and i had
ammonia 8ppm i was doing 2 water changes a day of 50% cuz that what the experts here said and it worked just fine. i used to do one febore i went to work in the morning and one at night when i got home. lots of work in a 75gal tank but worth it cuz i manage to save all my fish.
good luck!
Shawnie you should buy the python no spill thing. it works great!!! when i was doing daily water changes in my tank and had to do it with buckets it was sooooooo hard. i was using a 20gal bucket and draggin it up and down my apt and my back hurt so bad. now i'm all better and i love to do water changes!!!
