New tank syndrom,Brown algae and diatom breakout

[jpbeen]

I have a Red Sea 525XL3 month old mixed reef. Brown algae and diatom breakout in last month. Just installed a Vecton 600 UV sterilizer and water is pristine within 3 days. My tests results today are Ammonia-0, Nitrate-0, Calcium 420, Alkalinity-9 and Phosphate-0. Should I add a supplement for Nitrate and Phosphate? If so what do you recommend?

Before any recommendations can be made what are you testing those with?

 

[andrewey]

Exactly. It's very possible those numbers are due to poor tests, expired agents, or not enough resolution to pick up the correct values.

Testing with API; expires 4/2021.

Get yourself some other test kit high a higher resolution. My tank tests zero po4 and NO3 with api but tests 0.06-0.10 po4 and 1-2 NO3 with Hanna and nyos kits. If I just went with the API results it would leave me to believe I am bottomed out and need to feed more/more often but testing with proper kits you can see that's not the case and no action needs to be taken.
