250 gallonish plywood build

  • We are currently upgrading MFK. thanks! -neo
Has anyone has trouble with humidity damaging their stand? Also does the stand design look stury enough to support 250 gallons of water?
 
I am also currently building a plywood aquarium, and am planning on fiber glassing the edges. Can you tell me what brand of stuff did you use and where did you get it? I know nothing about fiberglass, does it come as a cloth that you apply resin to or is it a pre- coated cloth that you roll out? and also is their a certain brand that is fish safe? Thanks to anyone that can help
 
Nice build! I like your nailer. ;)
 
from experience, as long as the stand is varnished well, humidity will not be an issue.

just because i always take the precautionary route...(well u never know!) i am not overly confident with the base. from the pictures, all of the uprights are are on top of the flat base with only 4 struts at antagonist angles. i have no doubt it could support many many kilos with only down force its just the swaying behaviour of water.

ie eggs are super strong top to bottom but side to side,,,, not so.

my own personal preference is a rectangular frame with inside frame struts. the top frame is then a mirror image of the base. the supporting struts then sit between the upper and lower frames at antagonist angles. cross beams and uprights are then added at 1.5 feet intervals (over 3ft tanks only) each with parallel and antagonist angles (to beams at a right angle) depending on the hight of the tank i would add some arch supports as you have.

any way good luck and good work

I used regulay fiberglass tape for drywall, and poly resin that I bought at Home depot. I'm not to good with fiberglass either which is why I chose to just do the edges.
