Thread: Working on my first pvc structure

Riverrats

OK...most of my bases were larger square tubs filled with concrete, this kept the PVC trees upright and stable. You can also run rebar through buckets or small diameter PVC to serve the same purpose.
The Beauty of PVC is it's invisibility in water...if you start adding air holding stuff like soda bottles, etc., to hold it upright, you are highlighting the cover just like a fish's swim bladder does on fishermen's electronics...if you don't care if other's find it, then you're OK to add all the buoyant stuff you like!

DHW is right sand it all with 60 grit so algae can adhere and build good strong colonies....and put as much PVC together as possible...it will be pretty much invisibly.
Or if invisibility isn't an issue, put some laydown wood, shrubs, C' Trees, etc., around the outside, and in with it!

The reason Plastics can be invisible under water is because they have close to the same densities, then like Stealth Science, they have rounded edges, or holes, that allow sonar or radar to pass through....if you get a good colony of algae it also absorbs beams...unless someone has a underwater camera and the water is clear, most people will never know what is.
The reason Rocks, wood, stumps, fish, trestles, etc., show up underwater is because the densities are way different.
If you put PVC, in creek beds, humps, drop-offs, around wood, or near other natural structure or cover it will disappear into the scenery! Just make sure you know where you put it!

Im thinking about building something myself and this has gave me some good info. Looks like the pvc is the way to go to keep it from being found by others.
