Use the gravel cleaner every 3rd day with around about 6L being changed, then dose it with Nurafin cycle. Tank is still in cycle at the moment, on week 3 of being set up and the new pump has only been in there just over a week as the one I got with the kit was shite. Tank measures 500x300x250 (LxHxD) Albino catfish, about 60mm long. Golden lionhead, he's a greedy f**ker. White one didnt like its picture being taken. Tank at night. Added 2 moss balls and the pot for the catfish to go in, he's always in there. Water is still a lovely browny green colour, going though with water changes. When sticking wood in the tank, dont do what I did and stick it in after 2 hours lol.
