I recently purchased a 13 gallon enclosure, 50 watt heater, and Quietflow 10 filter as well as some Caribsea Super Naturals sand. I've done some extensive research and I think I am about ready to go get some other supplies. I have decided to go dry sand and dry rock to prevent any instances of stowaways. I was wondering whether I should begin my cycle with the table shrimp method or can I do something like ATM Colony? Also, is it better to buy pre-mixed water or to mix my own? 5 Gal of water is roughly $14 where I live. I would be more certain about mixing my own but I only have access to distilled water rather than RoDi water so I wasn't sure how that would effect it. Last question, is 480gph for a powerhead too much flow for my size enclosure? Not looking at corals quite yet, just trying to get my ecosystem established with a pair of clownfish and a small cleanup crew. Thank you!
