Hi folks,
The current iteration of my pond redesign has it being a round-edged square, 10ft by 8ft and probably 6-8 ft deep. Total pond volume including filter will be about 6k gals, with 4.5-5k gals free swimming space.
I plan on putting in two 4" aerated bottom drains and one gravity fed skimmer. These will feed a RDF, probably an electronics free Blue Eco at this time as the RDF pit will likely be filled with water.
Do I need to install TPRs in this setup?
A bakki running about 10k gph will be the main return.
I also plan to have an airlift running about 3k gph pulling water through a moving bed filter and oyster shell bed for backup in case the bakki pump kicks the bucket, and parts take a while to come in. I also expect to need to turn down the bakki at night.
I will set up a pond build thread with drawings when the design is more finalized.
I ask about the TPRs as I'd like to avoid coring holes through the pond's main walls. Insurance for bottom holes is an extra thick layer of waterproofed concrete. Not a hole lot of room for that with side holes. Pardon the pun
Cheers,
Ken
