if you have enough plants to keep the water oxygenated you don't need to constantly run the pump or have a huge pump going. unless you have a water feature like a water course or falls, then you need a larger pump than your pond has for water. the busier the movement in your water the more likely to have algae from the constant aeration. i have never had a UV filter on the small ponds but i know they are nice to have to limit the algae growth.
i do get seasonal flushes of string algae during rainy springs or when i would completely drain the ponds to do their clean out & inspection for cracks. (my mom prefers them to be cleaned each year since they are small prefab 'tubs'.)
if you are keeping fish in it, the pond will need to be about 4' deep in cold climates. my parent's prefab 'tubs' are not deep enough to keep the fish year round so we bring them in for the winter. also gives my parents the chance to check for any fish issues and see any new babies that may have been hiding from the bigger fish.
Bottom seems to be too large for the coworker to fit it on his truck or his trailer. Who knows if it will ever get here.
So we set up the top part for now instead!
Duckies have a new home, too.
One goal for me is to redo our small pre-formed pond this summer. I've given up on the idea I'll ever have a larger pond now that Spouse can't help with the building.
I love ponds, pond life, and the sounds and sights around a pond.
Time for an update!
The bog was guttet, back dirt had eroded and it leaked constantly. I wanted to just cut out some plants, but it all had grown into a ridiculous mat from heck. And in that stressful mess, I put holes in the bog's liner. =/
Anywho, kept some cuttings and tossed the rest. Also removed all the pea gravel, idk what I was thinking with that mess, lol.
