Sorry for not asking correctly.....
The thing is I have 3 mh 250w, 15k. (but want to change for 10k)
I bought 2 x 58 tek retro for supplement over my 100gl, i know is not much but just want to try, if need more i can buy another one.
My question is,
My mh bulbs can i change to 10k to get faster growth on my corals and since i bought the t5 retro i can add some actinics to help my tank not to get so yellow with the 10k bukbs...
And which bulb would be the best for that combo. I would like to know for both t5s and mh. Mh is SE.
Thanks
