Hi, so about 2 weeks ago I started a 29 gallon saltwater tank which I started with live rock and some live sand from my previous 5 gallon nano reef and some bio spira basically quick start. Ive been testing the water regularly every other day while doing 25% weekly water changes. Bio spira so far I am happy with, although its not true that you can add fish right away, it speeds up the cycle . I also have 11 blue leg hermits, and 3 turbo snails which do a great job of keeping everything clean. I noticed the first ammonia spike a week in, just a small one up to 0.25 ppm. I did a water change, and reduced the feeding a little and after a couple days it was down to near 0. Today after about 2 weeks I checked the nitrates and they are up quite high, around 50 ppm which is about halfway up my testing chart. I know they are supposed to spike near the end of the cycle, since ammonia and nitrite are way down at nearly zero. I added some seachem denititrate to the filter which I did with my old tank to help bring those nitrates down and finish the cycle a little quicker, which it did a great job of before. Basically all I want to know is, am I doing this okay? I definitly am waiting to add fish untill after the nitrates are down, but I just want to make sure that spike wasnt too high, and also if adding the denitrate was a good idea at this point. Heres my tank, I plan to add more live rock. as you can see I have a little on the side and mostly new dry rock since it was much more reasonable priced. Any other recommendations will help me a lot!
