Building Solar-Powered Pond in California: Liner, Filter, Plants

18x15 ft area, central CA coast. Solar pump, low maintenance, small fish, frogs, salamanders. Asks: concrete or liner? How to start?

Liner > Concrete

• Liner: cheaper, easier, flexible. 15-ft wide EPDM → 6-ft wide, 3-ft deep pond.
• Concrete: expensive, cracks, permanent.

Solar Pump Needs

• 12V DC pump.
• Good biofilter (essential).
• Full sun = floating plants (60% cover) for algae control.

Steps

1. Check local pond store for liner width, 12V pump, filter.
2. Dig hole to match liner.
3. Install liner, pump, filter, plants.
4. Expect web research — worth the time.

Local stores may know less than you — but start there.
