Two full years. Is that fast?Come together fast
Thank you. Many things are trial and error, that's true. I am still experimenting with the aquasock / shower head.Wow. You are very crafty. It seems like things hardly ever go to plans. So sad that you put so much time and effort into the shower head, for it to not work out. Great trouble shooting, and coming to solutions. This is very inspiring. Are your acharas in that pond now as well?
No. Only koi are in there. ~110-120 of them. It's risky to put spiny fish, such as catfish, in a rubber-liner pond. Sooner of later, it will get punctured in more than one place, which could be ok for an in-ground pond but may not be for an above-ground or partly above-ground one. The liner would have to be protected, e.g. by concrete or acrylic sheets, etc.
