Brettsker...low maintainence CAN be taken to the extreme. You do want to bait your own hook and remove your own fish don'tcha? :p After several months of not working on the pond anymore, you'll be looking for something to do. Water temps. at various depths, twice daily alkalinity and hardness samples, analyzing why one solar feeder goes off 15 minutes after the next.(all with graphs). You may even want to sample your stock via trapping, seining, maybe even fishing. Good luck. Dont let all those creative PVC attractors go to waste. Sorry, I cant add anything intelligent to the aforementioned recommendations(but I could help with the sampling part).
