  1. i've been doing custom plastic fabrication for a little over 6 years now. if you have questions feel free to ask me. we have a department that makes heavy gauge aquariums up to 3 inches thick.

  2. Just finished watching this series and it's been a very informative experience for me. I have my acrylic, weld on 4, clamps, and weld on 16 just waiting for my edge tool to arrive then I'm gonna give this a shot. My first attempt will be at making a 90 gallon 6ft long 18 inches wide 16 inches tall aquarium. I work at a glass company and have built glass aquariums in the past but never an acrylic one. Looking forward to the finished project and setting up my first lake Tanganyika cichlid tank.

  3. I'm a millennial so I'd rather just buy a used tank than build my own, seems like a lot of work. I do love watching other people build things though.

  4. Watched the six videos and the glass based ones. Learnt so much from you joey and your old content is fantastic. Some of the comments I read from people amaze me considering everything you've done to help people. Thanks again mate and glad you've had success you really deserve it

  5. How will I know if the acrylic has been flamed polished? I have acquired a used acrylic sheets but I don't know if the edges has been flamed polished or just polished by novus or any other chemical. You said that flamed polished edges should not be cemented together as they will break / craze. BTW looking from the edge it looks polished but I still can see some of the saw marks. Thanks

  6. Hey where can I find that calculator you mention in a video for determining sheet thickness? Also, will the acrylic panels bow like the top? I went to your site I only see "buy my book" which is actually very tempting tbh….

  7. Hey DIY king
    I want to build an Acrylic coffee table aquarium and put tree sides on it and have like windows in it to look tru and have a tabletop of a wooden board with an acrylic piece in the middle i wanted it to be 130 cm long 60 cm wide and 50 cm tall and thick acrylic would i need for that to be strong enough hope you would answer to this 🙂
    I love your videos and have seen many of them so thats why i want to have a sommer
    project 🙂

  8. i have to start by saying outstanding video series!
    this has inspired me to try my hand at constructing an acrylic aquarium and stand that realistically isn't available locally and would be spendy to have built otherwise.
