Matt!
Great Build there!
OCEAN SIZE - Thanks! I agree 100% with you as well. It's extra security, and a bit more strength.
Let me rant a bit (keep in mind I AM not an engineer, but I did stay at a holiday inn express last night!)
The only problem I have with using the L-Brackets and mounting brackes for joists is rust and corrosion. I believe that the stick wood mounting brackets are susceptable to corrosion. Particularly in the salt water environment that we're going to put our stands into.
This is why rocketscientist has built such a great stand. it's all butt joints and direct wood support. If you built the stand and rubber banded it together, it would actually probably still support most of our tanks. (until the cat knocked it over) - but it would definately hold the tank up!
To prevent corrosion - This requires, a very good, and very complete seal. Otherwise there may be problems. Particularly for direct load bearing type Joist brackets.
So for me - the L brackets were used in places that were not load bearing. Rather only in places that were "placekeeping". So that if they ever did eventually fail - the failure mode would not be catastrophic.
If I used the metal joist hangers - (which I did not) and one rusted, and then failed - the failure mode would be a tank that falls through the top of my stand. NOT acceptable.
Where as if an L-bracket above fails - I would then have a stand where a support leg could possibly be shoved out of position. Not an easy proposition with 3000 lbs on it.
Anyway - just my non-engineering thoughts on using metal in the stand.
