ISO will do it too, there's a good write up on here somewhere about what setting to use if you have a DSLR, can't find the link right now though. ISO setttings change your Fstop though, so you will have a faster/slower shutter because of it.

here's my bookmark for re-remembering what each does:

dottybacks are cool little fish.....although somewhat aggressive at times....Ive had a neon and have a sunrise now..... grammas are cool too......and if you dont mind spending a little more you could think about assessors.....my 25g has a blue assessor, a small fairy wrasse (that will go in the big tank soon) and three nano gobies.......two trimmas and a green striped goby.... the 25 also houses a plethora of small inverts..... sexy shrimp, pom pom crabs, two different kinds of porcelain crabs, emerald crabs and a few feather dusters.....it makes for a cool (at least in my mind) tank

sorry noob question whats "DSLR" lol.

I have a nikon p500 and I dont speak english when it comes to this stuff haha, I'm pretty uneducated in this area

Nice camera! yeah, you should be able to do lots with it in time, i used to stick to auto mode but have started playing. Try going in aperture mode, set it to a low number, i think you should get 4, then change the ISO to 200, and white balance to a florescent, or shaded setting. then you can take a couple to see how it goes.

Your camera might have an auto-set white balance feature, that you can put something white under your lights, and it will auto set it to that.

If that's too much, just try the different scene modes to see what works, i've noticed my night and landscape ones take good pictures sometimes.

Try some non photosynthetic sps. I have a sun coral and a chili coral that do fine under T5 ho's, also zoanthids add some nice colour, with high calcium your coraline algae starts growing and the wow factor will go up. maybe get a couple anemones too. Maybe a nice rock flower. Get some colour in it, like yellows, reds, and purples.

no I cant do nems I only have 20g I could but I dont want the hassel, I have 4 types of small zoo frags and a ricordea, mushrooms gsp and a kenya tree. I dont think my tank is old enough for sps

Thanks yeah its good for lots but when it comes to this, tanking pictures or video of the tanks has been my biggest challenge, but its a goal! lol To take some Epic or decent pictures! I got a few good ones of my cichlids, and they have t5s as well, so I'm not too sure why it doesnt work with my nano, could be the LEDs maybe throwing it off

What do you feed your tank?

Didnt know I needed to feed it lol
