Okay Okay!! we just had lunch, and my mom was a whole lot happier with the idea of the IM 25, she said that if I paid for $50 of it my parents would get me the tank for my birthday, so thats what Imma go with!
as far as lighting goes I am going to start with my diy spotlight and a nicrew 30 watt pendant style fixture ( with ramp timer ) and then later upgrade oto the nicrew light as my spotlight, and an AI prime hd as my main light.
for sand I am going with large grain crushed coral, it may not look the most fly, but as seen on my current tank it is easy to clean, and rock will be the same as my current tank, but I am crushing some of the larger pieces, and scaping it ( which should be easy with the nice dimensions of the IM 25 lagoon ) and don't mention that I am going to dye the rock cause I hate the not so established phase, especially when my rock is mixed live/dry rock.
that's my plan, I hate that I will be scrapping some stuff, but I think it will be for a better tank
Build thread coming soon! ( as in when I have anything specific ready for this tank )
