You mean not even a sponge filter? I think you'll end up having to change water more than once a week with no filters at all. I don't know for sure though.I am trying it without a filter.
I NEVER get that lucky to find deals like that. Wow. Great find. No LFS stock 2.5" anywhere close to me. Only the big chain stores have them and they are $14 each. I know they cost more because they make less of them, but it still kills me to pay more for a 2.5 gallon than I do for a 10 gallonA guy on the Craigslist were selling them for $7 each but he decided to trade for them.
I was not criticizing your build. I was only trying to be funny about how some people over build things... which is nothing wrong with that either. But I think you did a very good job. BUT.... I still would not trust that one metal bracket you have in the back. I know that since it's not already leaning that it does not need a lot of strength in the back to keep it from falling forward so in theory that metal bracket would be OK. But still... you've got such a nice stand, I'd at least put maybe 4-5 of those brackets in various places in the back at the least.I did think about using 2x3 but I knew that it will not look as good as 1x2.........I have also supported the back with a brace. This should be strong enough from falling forward.
Anyway... keep us informed with pics once you add water and shrimp.
Are you going to add any lighting?
