2T5 HO's would be more than sufficient. - Edit - and by 2 I mean, 1 lighthood that has 2 tube sockets.
just a reminder that the hoods do not come with tubes, so you need to purchase them separately.
most shops have 18000K tubes in stock, and those are my favourite but they cost a fair bit - I use them with excellent results.
If you want 10000K or 6500K tubes you might have to order them in, or try an electronic wholesaler or a local lighting store.
I'm hoping price is not too much of an issue for you. :lol:
the T5 hoods come with reflectors.
I would recommend any retailer that you have dealt with before, and are happy with the service. It would also help if they had the hood in stock, lol.
it would also help if you told us how high you wanted the tank to be.
