- No3 level was off the range ... super RED; from memory, it's above 120 ppm :mad:
- After adding some Siporax media in my sump and NoPox dosing for considerable amount of time, the No3 level has dropped to undetected level (0 ppm).
- Stopped dosing NoPox and No3 is still at undetected level (0 ppm)
- I have been quite aggressive in feeding my corals & fishes with frozen brine shrimps & reef roids, so the No3 has gone up a bit to 10 - 20 ppm.
- I'm aiming for accelerated coral growth with my water targeted at 10 dKH Alk, 430 ppm Ca & 1,350 ppm Mg.
- Using Red Sea Foundation A, B & C to maintain these elements.
- As per @Randy Holmes-Farley advice, there need to be nutrients of at least 0 to 5 ppm of No3 in the water to avoid burnt tips at high Alkalinity which at the same time achieve the objective of accelerating coral growth.
- The tank is 55 gallons with fishes, LPSs & Softies dominated.
- Fortnightly to monthly 10% WC with ASW @ 1.026 SG.
- Is there any issue in re-starting regime of NoPox (or Carbon dosing) after stopping for quite a while? In my case, 6 months or so.
