Another small waterfall/pondless feature rebuild for this week! This one was a cold one 🥶

Customer only had 2-4 days worth of run time on the feature. We added two Pondless blocks and a big pump vault, As well as a new liner! So now we should see 3-5 weeks worth of water holding depending on evaporation.

Another waterfall rebuild we did two weeks ago in order to fix the old leaking one. this was pretty decent size with some pretty good size rocks! Had to use a mini in order to move them. Tried to match existing look but add length to the falls and get rid of the old biofalls box!

Before, durning, and after of a small half day waterfall rebuild last week! 💦 🪨

Keeping it simple but effective was the goal ‼️
