Radiums and LEDs is game over.IMO even the coolest temp of MH bulb (currently 20K as far as I know) still emits too much white. It will boost acro growth, and give them good color. But if you want all the crazy rainbow color you have to either go with a smart T5 maneuver for a very blue/purple spectrum, or LED. You can combine MH with T5 or LED, but to me at that point why even bother. plus, the energy bill .... ugh.
ChIsn’t game over bad. Maybe you mean next level
I have 14 fish. 2 large - purple tang and fox fac. The rest small fish. I feed them twice a day 1 cube and equal size piece of LRS 2x daily.Get back to the basics... stability and don't dose anything that you cannot test for. Change some water if you do not.
I would throw the element supplement in the trash unless you know what is in it and can test for all of it. The problem with those all-in-one supplements is that you, for example, might be driving manganese too high in order to get some iodine or strontium. You are better off just changing some water and introducing them that way, or dosing nothing at all.
I do NOT use LED over my display tanks, so take this to mean nothing, but when I extensively tried them, just ramping up for a bit, then steady and then, a short ramp down was about as good as it got. I would not get too cute with the schedule, but I also would not change anything too quickly.
Lastly, remember that N and P need to be available for the corals to use and residual levels mean nothing. Zoox cannot use nitrate, so they have to get their nitrogen from ammonia, so if you are not feeding your fish, then your corals are likely deprived of nitrogen even if you have no3 in the tank. Some P is needed and at .10, you are fine, so don't worry about this. Do you have enough fish and are you feeding them a lot?
Spectrum shifts means you have a bunch of different combinations of different wavelengths in various proportions. Mine are all equally proportionate. I have the same spectrum throughout but at variable intensities (par).What do you mean by spectrum shifts? I can see that you are using much more intensity but the light ramps up and down throughout the day?
