Im new to the saltwater community. I set up a 32 gal cube I cycled it witha table shrimp per my LFS advice. I added 2 clowns and a skunk cleaner but i checked my nitrates and theyre 40ppm. What im confused about is my LFS said DONT do a water change after cycle is complete but my ppm are now 40 so i know i need to do a WC but can someone tell me how much I should do at 1 time im afraid if i do a drastic itll kill the fish.
