hello, i got a 35litre tank, which had been set up with filter, light, gravel, plastic plants, etc. it stood for about a week. we went to local fish shop, we brought one black moor fish. we had him for about a week and a bit, he looks fine and eats well, but i am worried now because i have been reading about the nitrogen cycle. i have no test kits. i do do 50 - 75% water changes every other day. will this be ok. its done every other day because i have to leave the water to stand, so that it is declouranted.
