Add your ammonia source. Then wait for your ammonia to spike then nitrite to spike then when these 2 both fall off to 0 ppm and all you have is nitrate do a large wc (50-60%). You can add some cuc here but don't go crazy because you don't want them to starve. I would wait until your nitrates below 10 ppm before adding a fish
Ok so pretty well same as freshwater. So I can alrdy add snails now or should I wait
