Hey guys, thanks for the amazing info!
Bob your tank is becoming very nice! I wonder if I can work so well with wood like this.
I was thinking today of making one of those dug into the ground, but was wondering how I could protect it from the water coming from the sand in its sides.. I guess that you can use the same process that you use for the inner side for outside, but I also think that the work would be very big and it would demand big money if I could even find material with the same quality that you guys have there!
There are many point to be observed but I think that with a bit of planning they can all be overcome!
