I have built "touch tanks" aquariums that hold hundreds of gallons of salty brine water for sea creatures to live in where people can have hands on experience with them and they have not deteriorated over many years of use. Build a tank the size and shape desired out of exterior plywood and use chopped fiberglass and marine epoxy.
Am I better off using epoxy or is fiberglass resin do-able, which is also much cheaper?
I use West System epoxy...locally it was a $100.00 per gallon a couple years ago, last time I looked.
When doing large projects We used five gallon buckets of epoxy and hardener in one gallon cans. Follow recommended mix. I recommend using slow hardener if not use to working with it. The fast will go off before you can use it in hot weather. Use 3 inch fiberglass tape on all joints and brush or roll on epoxy. Chop fiberglass and roll on epoxy. Lightly sand after dry. Apply two more coats using fiberglass and then epoxy and lightly sand between coats when dry. The final application needs to be sanded smooth to avoid any hangs.
Must use breathing protection and eye protection from the glass during sanding. Provide plenty ventilation.
