I have finally cycled my tank and am hoping to get some clowns this weekend but would also like to add chaetto in the back of my sump. My PH is 8.2 Ammonia 0 Nitrite 0 AND Nitrate 5ppm. I read on another post that you need to add chaetto before you add fish but can I add at the same time. Will be adding coral and inverts in a few months. Very new to the saltwater hobby.
