i love bamboo, giant bird of paradise etc but do NOT put next to your pool. In our last build we used Zanadu. Big leaves that do not drop and bullet proof. Perhaps find another way to cover the fence other than plants that almost always drop their leave and have invasive roots.

it's never perfect and always involves a balance/compromise to achieve the less noticeable outcome - it's the decision with the convergence lines as to whether the base run is cut or the wall. That the wall run is cut it accentuates the pool fall more - if it was the other way around, in that the wall run comes down to a straight/horizontal line and the base is cut into that line the angle would not be as noticeable......you can fix it, and in this case arguably due to the window perspective looking straight on it's a justified request - adding water won't improve/soften the end result dramatically in this case IMO....that main thing is that it's been prep'd straight which it looks like it has been - this is only cosmetic remedial, which whilst yes will cost the contractor, you have to live with the end result so it's worth the (hard) conversation......good luck!

watchedpoppy, here's something about heat pumps designed for cold temperatures. Note, these are reverse cycled air conditioners (air-to-air), not pool heat pumps (air-to-water). I don't know how heat pumps stack up. It's an American site, so FYI -13F equals -25C. http://www.mitsubishicomfort.com/benefits/hyper-heating On a side note, temperature is just the product of the motion of atoms & molecules (kinetic energy). These are in motion all the way down to zero Kelvin (-273C). So although it may feel cold outside, there's still energy available in the site, although heat pumps do become much less efficient when it's cold (the difference in input & output temperatures is important). One thing that has made heat pumps very inefficient in the past is that the condensing coil would ice up at around zero C. This would have to be thawed out with a plain old electric element (COP of 1). Greatly reducing the overall COP in temperatures around our below zero C. But the modern heat pumps, which use the CO2 compressors Luxury Home Heating has talked about don't have an electric element to thaw them out, greatly increasing their efficiency. As for the noise issues. Some modern heat pumps (but not all) are very quiet. So just pay close attention to the decibels they produce, listed on their spec sheets. FYI, here's a good read. Though it doesn't mention solar PV, which would be advantageous for a heat pump. https://www.pooledenergy.com/blog/choosing-a-pool-heater-what-are-the-relative-performances-of-solar-gas-electric-pool-heaters/

by the way, we had pebblecrete in our pool for 28 yrs. I think it was certainly very hardy ie. bits haven't come off. Algae can grow in the cement bits around the pebbles if you let the chemistry go off like after alot of rain. It was easy enough to scrape off and generally disappeared once I shocked the pool but it did seem to come back in the same spots again if I didn't keep close eye on the chemistry thereafter. The pebbles we had felt a bit roughish under foot, it's not a smooth surface. It was in no way uncomfortable to walk or sit on though. I would get it again, and still might if I don't like the sound of the glass....
