Is this going to hold

A36 is the most common and readily available steel grade used in structural fabrication.

If it is possible go with 2 mid supports splitting the tank length into 3rds.

In the states for the most part. A36 yield and tensile strengths (36K) are no where near what Canada uses or at least Saskatchewan. Tubing and beam are most often called with a 50K yield and bars with 44K.

Are those popsicle grade or fudgsicle grade sticks? You might need some cross bracing in there, esp if you're gonna use a wavemaker
