Update:
The tank has been filled for over a month now. no issues at all. The liquid zavlar rubber coating has turned brown as it was reported to do when submerged in water. no effect on the water. water in the tank still matches my tap water. I am now in the plans of building a bigger tank with this same concept.
I recently moved and the tank did fine during the move. i ended up setting it up in my new place and them decided haveing it upstairs was a bad idea, so i then moved it down stairs, which it also survied. I was able to move it on my own which i would have never been able to do with a glass tank.
I am still working on filtration. Right now i have two 1 inch bulkheads plumbed into it, but thats as far as i got with that. i will be doing a wet/dry still to go with my fx5.
I also added two silver arowanas to this tank two weeks ago to go with my stingrays. The marble motoro i ordered did arrive on schedule, but it was DOA, so i replaced it with two aros instead which survived the flight just fine.
I also added a few discus to this tank(not pictured yet)
all fish are doing great.
full tank shot is after feeding, so a bit messy.
