Decided to set up a rack a home to house all my shrimp tanks in one place. Found this kit at chain hardware shop.
150kgs per shelf, extra wide, and in black (the shelf has to be black) ... Perfect, right?
WRONG!!!!
It may hold 150 kg per shelf, but not without a massive bend in the frame - meaning none of the tanks sit level. Not only that, the whole frame shakes whenever someone walks near it.
What's wrong with this picture?
Notice the difference in the size of the gap between the top and bottoms of the tanks? This was even after I had chocked the middle of the tanks to try to get them sitting level.
It only got worse when I added new tanks (larger - shown empty below).
I even used two mdf shelves as one shelf. Also added the braces from the shelves I wasn't using to try to get the whole structure more rigid. No difference at all.
Note also that you can't really have two 2 ft tanks sitting next to each other easily either. Other shelves I've used in the past say 1200 long and mean 1200 between the posts. That's useful. 1200 outside the posts is not useful when you need 4 feet!
Oh and one more thing: The middle shelf has to always go in the middle because it holds the end pillars together - the shelving isn't as 'VERSATILE' as it advertises on the box.
If you are looking for a steel rack, please learn from my mistake and spend a little extra to get a 'pallet' style of rack. Save yourself the angst.
I'm currently setting up a new rack - 'Rack It' brand which states 750kg per shelf, although the shelves will be only 400 mm wide. Based on the solid construction of the shelving brackets, I'm sure these will do the trick. Fingers crossed!
