AI Prime question

[Mike1995]

Would two ai primes be good for my 75g? Which version is for reef tanks? I wasn't sure.. there's like 3 different ones .
Can a lighting schedule be made for these lights? What corals etc can they grow?

For a 75 I would go with 3 primes. They are controllable with a computer or smart phone. The regular prime HD in either black/white are for reef tanks. The freshwater version specifically is called so. You can grow anything under them, it just depends on placement of the coral up high, on the sand bed, etc. Also you can start with two, just keep in mind you will probably want to add a 3rd. Only obstacle with a standard 75 is the center brace so keep that in mind.

I use 4 AI HD Primes on my 75 Gallon with good results. They run great and do well.
