I have 2 x 250w MH and 2 x 60w actinic now. My friend has his tank with 2 x 400W MH and 2 X 96W actinic. We both picked up a frag of the same stuff (montipora digitata) and within a week or so, our frags look different.
His has turned more blue-ish in colour and his polyps stay really close to the skeleton of the coral.
Mine has stayed brown but the polyps in mine are extended twice as far out.
Being very new to corals, I am unsure which one is healthier? I like his colouring and like my polyp extension...
The blue-ish tint - is this due to the higher intensity lighting? If so, what suggestions can anyone make for upgrading my lighting besides just going and grabbing a set of dual 400W
Would adding some T5 strips to my setup make any difference? Increasing my actinic supplementation?
