I'd been looking at some of your pictures of your NPT's and love them. I've also read a lot of the tips that you've given on how to do them, as in putting soil down first, then plant substrate, making sure the water is clear before putting in plants, and how you need a lot of stem plants as well as a few floaters. I wanted to do a shrimp bowl as an NPT and saw that you said you add the fish that same day. Do you not have to worry about letting it cycle or anything before hand? And is a filter necessary for it starting off right, I know you said that you took them out after a while, but i didnt know if I could just not use one at all. Thanks in advance for any advice!
