Guys, I’m going to mount 4 bulbs with these parameters in my T5 panel https://www.mrosupply.com/lighting/ballasts/fluorescent-ballasts/1854552_flft521w835_fulham-lighting/ it is 21W or to take something brighter?

the new LED panel will be expensive I think. Is it really consumes less energy? Is it worth of spent $$$?

I want to buy green palys, leather and pipe corals, and some hard corals.

Hi, Here is another question from the newbie.. Well, I really can’t understand the light parameters for the reef tank. Are there any standards to follow? I have currently the old fish tank panel that would be suitable for 90gal tank. Can I use it for my future corals? Thanks

Hi Folks, what type of white sand do you buy for your reef tanks? I want it to be always pure (if it is possible). Should I buy fine sand or not? thanks

Hello! I’m Fred. I want to keep the corals. I hope to learn about the reef tanks here.
