His tank is cycled if its reading 20ppm Trates
Yeh it has cycled. So if im changing water (still not sure on how much to change haha) should i do it in one go or say x amount of 10 litre buckets throughout a week?
Im now also confused about gravel cleaning. I did clean the gravel today and got a fair bit of waste product out of it.
Im also now seeing conflicting info on how often to clean the filter media (i know i need to do it in tank water thats been removed)
Im beggining to get that its more about an idividuals water chemisty and/or preference lol. Thanks for the info though people, appreciate it
