How to Keep Purple Acros Purple?

[mic209]

My last tank, I couldn't keep blue acros colored up. This time around, my garf Bonsai and tri Color valida are dull purple, border line brown. What does purple need to be purple? Everything else is doing great, here's a top down shot under 14k setting with the radions. You can see the GARF Bonsai in the center towards the bottom, it's doesn't have the nice dark purple coloration it had when it was a frag.

Here is some interesting viewing as well as reading, check the links/reading articles mentioned in the video, they talk about lighting, intensities and colors...

In my experience, assuming parameters are ok and no alk swings, coral will dull their color if the lighting isn't correct, be it too much or too little. Usually too much light in most cases.

Bonsai acros need potassium . You will have problems if it dips below 400ppm

Stable ALK and not TOO much light. Shoot for 280 -300 PAR, very stable alk and good flow and the color will come. Bonsai takes a while to settle in and color up... for me anyway. I haven't kept it in a couple of years, but remember it frustrating me until BAM it seemed to color up overnight
