After doing some research on building a acrylic aquarium, I decided it to be to much work compared to the saving of a already built aquarium.
You need the tools, the correct type of Acrylic and everything needed for a tank, and it the process of doing this, is it going to be 100% perfect? if it's not you just wasted your time and money because if you correct a mistake it will show, since th bonding method stains the Acrylic and all other mistake that can happen should be thought about before trying to attempt this in my opinion.
If you have all the tool and the skills to do it then go ahead, but for a beginner with no tool, I'm not sure if it would be worth it.
Just throwing that out there for anyone who doesn't know already

I almost jumped to it until I did my research
I read this on one website while researching
" US made Cell Cast Acrylic material The ONLY material
recommended for Aquariums. Cell Cast Acrylic is stronger and
clearer but most importantly, it does not absorb water like extruded
acrylic which weakens over time leading to potential disaster! Some
fabricators use extruded material to save money and charge less -
Ask yourself this: is a few hundred gallons of water on your floor
worth saving a few dollars? "
Does anyone know where to get good quality 75 gallon Acrylic aquarium cheap around the Everett area?
I have a 2 1/2 year old in the house and I always think about what might happen if he hit the glass with something on accident
I had a 10 gallon a long time ago that was in the kitchen, the cat jumped on the back of the chair and hit the aquarium... That was alot of water to clean up, I don't wanna clean up 75 gallons and a dead fish...
