7-year Itch? (Checking on Water)

I cannot believe it's been over 7 years since my water experiment started (First post about water effects). Over 2,640 days.

So it's time to check in and see how they are doing:

Day 1 of experiment

Day 2,640+

By far the worse for wear is the Scenic Water:

Pock marked and discolored slightly

Has dust on top of it too

Scenic Water birdbath is not only pock marked but it is also dusty. And I am unable to clean it because the surface is spongy so there's no wiping off the dust.

Next up we look closely at the Solid Water product:

Cloudy streaks have gotten worse with time

Although it is firm on top allowing me to dust it and keep it clean, the cloudiness streaking that happened on day 1 has continued to get worse over time.

And the Enviro Tex Lite product results:

Both Enviro Tex birdbaths are solid on top (allowing for ease of dusting and cleaning) and look fairly similar to the day they were poured. The painted birdbath fell and broke last year and I reglued the red mushroom ring back in place (see the cracks at 10 o'clock and 12 o'clock?) and you can see it didn't affect the water at all!

All of the products together (Enviro Tex top left, then Scenic Water top right, Solid Water bottom left, and Enviro Tex painted bottom right)

So here it is, over 7 years later, and I'm inspired to add a new water feature to my upcoming project (a fountain with a pond). Glad I know from this experiment which water product I should use!
