you got it Warren...still trying to find the sweet spot for it to get that rich purple color and growth. I had it high and it encrusted, but did nothing for many months...midway same with alittle better color..now I moved it down lower.....any tips would be appreciated.
Hey Mike - I have heard some people that swear by keeping it lower to maintain the deep purple color, then I have also heard other people who keep it high to keep the purple color. I think in the end it depends on the individual tank. I think you just have to move it around until you find it's sweet spot.
