I just purchased two retro's for 175W MH
lamps with ballasts. I am looking through some vendors websites and am confused about the various types and varieties of bulbs.
First off my tank is a 75gal that is 36" deep with a 5" sand bed it has 2 clowns, a scooter blenny, a cleaner shrimp& a bunch of hermits and snails. There is also 100+ lbs of LR
, with some growth showing. I have just reg flour now. and am planning on mainly soft corals. The lamps I bought are mogul base.
-Are German made Ushio the best?
-what about the K
spectrum? There are all over the range, what is diff between 10K+ and 20K? vs. a less K
-colors; I have seen white, crisp white, bluw/white, blue, yellow, whats better?
Any and all help would be greatly appreciated as always.
