redsea reefer nano

Hey guys, here is my very first saltwater tank. I’m very excited!!! I’ve wanted to start one for years now and I finally did. Any advice for a new reefer? Especially on how to deal with diatoms? I’m on week 4 now and it’s starting to explode!

Although the stock sump for the reefer nano does its job, I am looking for a better one with more features. There are a lot of options for the bigger reefer tanks but I have not seen any for reefer nano. There is Eshopps cube sump but it is smaller than the stock sump I believe. Does anyone make...
