How is everybody? Heck yeah it is Friday; paycheck day! Yippee yahoo!
So, how do you like my headline picture? Pretty cool, and scary too. I had to squint, and do a double take, I think that is a Grisly bear. I hope that acrylic is very strong. Got me to thinking though…
Our pond isn’t all that deep, unless this guy is kneeling. Heha whatever, we’re not building a swimming pool. But the idea is the pool window should be strong, and that is what Luke is proving. The force delivered to the glass or plastic needs to be able to handle the occasional shock wave. The concern is bending and techniques for holding the seal as the membrane, whether it be tempered glass or one inch thick acrylic moves from fluctuating water pressure. http://www.koiphen.com/forums/showthread.php?83305-what-is-better-for-a-pond-window
We’ve bought from this place before. US Plastics is where we got the vinyl ester resin for potting the copper coils for our wind turbine alternator. I don’t see the size I want: I was thinking 24″ high by 48″ wide. The Aquarium like side will be exposed to the sunken sitting area of our earth-sheltered aquaponics greenhouse, man that’s a mouthful.
One big difference of course is where this is obviously “Upscale,” ours will be more “Poverty scale.” I enjoy exploring what can be done on a reasonable budget. This is how I built my biodiesel processor, and how Kevin and I built the wind turbine.
This doesn’t seem like rocket science to me. The open top glass windows will flex more than a frame surrounded window.

As a technician I always feel more confident going past the sweet spot just to be certain I was at the sweet spot; meaning adjust it until it (whatever it is I’m tweaking) is worse on either side, then bring it back to center between the two observed “edges.”
Hell yeah reef keepers are awesome, but I don’t have that kind of time to dedicate to an aquarium, no, hell no.
Just to help keep my mind on the fact that we’re building a greenhouse as much as a pond here is some good reading from Hydrogalaxy on the topic of pH http://www.hydrogalaxy.com/blogging/what-is-ph-and-how-does-it-impact-your-plants/?utm_source=BLOG&utm_campaign=190905cf71-9_11_blog9_9_2014&utm_medium=email&utm_term=0_ab3325422e-190905cf71-80731337
Alrighty then, got to go pull off another series of micro-miracles at work. Then I’ll be back here, with a little luck and a lot good vibes, start laying in those massive rocks in the pond. I plan to stand them and hold them in place with ropes and cables, mortar them in place, and after they’re all set like I want them, I’ll put together a concrete mixing crew and pour cement in behind the rocks to create a seamless footing to keep roots out of my pond. I still have not decided if I’ll coat the whole inside of the pond with insulation and urethane. These rocks are so large the area of mortar exposed to the fish is going to be minimal. Coincidentally that pH discussion holds very true for fish as well. Cement is highly alkaline.
okay for sure this time
