The second would be responsible of using up the Nitrite produced by the first group of bacteria and converting it into Nitrate. In a complete cycle, we will be looking at the growth of 3 different types of bacteria, the first being responsible for using up the Ammonia released into the tank (either through a decomposing market prawn, decomposition of excess fish food or through fish waste) and converting it into Nitrite. The product of a proper N-cycle should be beneficial bacteria growth among your rocks and other bio-filter media in your sump. All it shows is that there are Nitrates present in your tank. Growth of algae doesn't really represent anything on the N-cycle. I am wondering whether the n-cycle finished yet. Just 2 small piece live rock in refugium, and using artificial live rock on main tank. Over-sized skimmer: for 1000 liter (plan to do a sps tank) Tank size: 30" x 18" x 18", main tank about 150 liter water, refugium about 30 liter. brown algae start to grow on artificial live rock Day 1 is 0, Day 2 is 12.5 and Days 3 onward till today is between 12.5 to 25.įishes and coral all looks good.


I am not sure whether n-cycle staring or not.ĭay 1 setup, everything's fine, tank set at 25 degree, skimmer on, refugium on 7x24, with some Algae in the refugiumĭay 2, the tank start to appear some brown algae but not bloomĭay 3, added 5 small (about 1/2 ~ 1 inch) clown fish and a Ricordea Yumaĭay 5, added Seachem matrix 1 liter, denitrate 1 liter, and active carbonĭay 6, set timer for refugium light to be switch on from 19:00 to 08:00, chiller set to 26 degree Seeking advice about N-Cycle, i just start a new tank and it has been running for 7 days.
