Thats a gen 1 stand, I didnt get one like that cause of the center piece, woulda made working on it a pain I figured. All teh deep blue stands are made out of particle board so you will get some life out of it but it will most likely need to be replaced at some point. The store I bought it from even told me that they are notorious for doing that and if he had known he would have had me go with a custom stand when I first got the tank a few years ago.
As for the lights, nope no top, I dont have any jumping fish, at least i dont think they will be jumpers. lol Better gas exchange for the tank and helps keep the pH stable.
Any setting on the light would be fine, its up to what you like, you can use one of their built in settings but if you want different times or color combinations then just manually set it up.
I would say for fish only, keep your lights on for no more than 10-12 hours. That way you can admire your fish when you leave for work/school and at the end of your day. lol I run my 90g fowlr
with blues from 10 to 12 noon, then the whites come on at noon and stay on with the blues until 9pm when the whites go off and the blues stay on til 11pm i think. I dont run moonlights, fish need some sleep too!
