In the beginning of January I started a nano reef in a 20 gallon long and it's going ok but my tank is progressing kinda slow. It's been cycled since the end of January but i have no coraline growth yet and water parameters aren't stable. nitrates- 0 ppm phosphates- 10 ppm salinity-1.025/6 ph- 8.0 alkilinity- 8 ppm. I use RO/DI water for everything, topping off every day and 10% water change biweekly. All that's in the tank is 2 snails 2 crabs and a little GSP frag thats doing pretty good. My clownfish and filefish are chilling in quarantine for 3 more weeks. Equipment wise I'm running a Chinese black box light, a ac70 filter with carbon, gfo, and filter floss and a ac50 as a mini refugium but I haven't set it up yet. I also have a cheap wavemaker from Petco but it does the job. Yes, I would have a sump but because of where I live I cant. Anyway, any recommendations on things I can do better to help build a good foundation for the tank to mature on and how to keep everything stable? Also, how to keep algae down? Thanks
