Alright, so my dad took a look at it and gave me a few pointers... (as always, lol) So, this evening I did a little more work to the frame and this is what I got:
So, basically, now I can basically sit on it and move around and it's pretty much solid as a rock. It was skewed a little, but I got it all fixed up. I also got the frame adjusted and flushed for fitting plywood. I have soo much space underneath the tank now. In fact, I know exactly how I want to place my algae scrubber now... and I am going to put the 5 1/2g RO Water storage tank beside the sump, and put it on a float switch, when I get the chance and money. Won't be that hard to do at all.
I also bought plywood today! woohoo! I'll be bracing up the top and bottom of the stand a wee bit more tomorrow, and then maybe putting a few pieces of plywood on it as well.
How hard can it be to put a piece of plywood on top of the bottom boards and cut out all the places where the legs go?
