Sps color and radion

[waynemah]

I recently switched to Hydras and the color was dull compared to my DIY (Royal Blue and Cool White). I found they lost luminescence and reds went away completely. I boosted the RB along with the Deep Blue and UV (now all blues are running at 80% with my whites at 100%, greens and reds peak at 30%). Colors have changed drastically within the last week.

The other factor is ALK for me, what are you testing with? The higher ALK the more pastel the colors get, with 9DKH being the breaking point for SPS health.

Do you have any pictures to show the colors?

Haven't tested potassium. I do a water change every three days(5g) on 40g system

I test alk with elos

I was running at 20k but found I was getting more encrustation and less branching

I do also have a blue assessor but he only comes out in evening

Pick suck as I don't have good camera

You should make sure your salt is not deficient in potassium. We are currently using the new Fritz salt and it is highly deficient in potassium (290ppm) so we buffer it up to 400ppm and it makes a big difference in coloration.

I would start by adding more fish and feeding more. Either that or start broadcast feeding some oyster eggs and rotifers.

I agree. Undetectable PO4 is not necessarily a good thing. Your corals could probably benefit from some nutrients.
