Agreed, rainwater setups are definitely simpler to manage. I've found pine mulch works fine if you refresh it annually and keep an eye on drainage. Greywater systems can be effective, but the upfront plumbing hassle isn't always worth it for smaller properties...

Totally agree with this point—looked into greywater myself and the cost-benefit just didn't add up for our modest yard. Rain barrels were way easier to set up, and honestly, they're pretty low-maintenance once you get a decent filter screen. Only issue I've had is algae buildup in summer...anyone found a cheap fix for that? Heard copper fittings help but haven't tested it yet.
I've had decent luck with copper fittings, actually. Dropped a few small copper pipe scraps into my barrel last summer and noticed way less algae growth. Not a perfect fix, but definitely cheap and easy enough to try out. Also, keeping the barrel shaded helps a ton—mine used to sit in direct sun and algae went nuts...moved it under an overhang and it's been way better since.
Copper fittings definitely help—I tossed a few old pennies in mine (the older ones are mostly copper) and saw similar results. Another thing that helped was adding a simple mesh screen to keep out leaves and bugs...less debris means less algae food, right?
Copper pennies, huh? That's a neat trick—I might have to raid my coin jar later and give it a shot. I've heard copper helps keep algae at bay, but never thought about tossing pennies in there. Makes sense though, copper fittings can get pricey, so why not repurpose some loose change?
The mesh screen idea is solid too. I had a rain barrel setup a few years back, and honestly, the biggest headache wasn't algae—it was all the random junk that ended up floating around in there. Leaves, bugs, even a confused frog once (poor guy). After adding a simple screen, maintenance got way easier. Less debris definitely means fewer nutrients for algae to snack on.
But here's something I've been wondering about: does anyone notice a big difference in algae growth between greywater and rainwater setups? I mean, greywater has soaps and detergents—wouldn't that stuff discourage algae growth naturally? Or maybe it actually feeds them more? I'm genuinely curious because I've only ever done rainwater harvesting myself.
Also, speaking of copper...is there any concern about copper leaching into the water if you're using it for gardening or veggies? I know it's probably minimal, but still something to think about if you're watering edible plants regularly.
Anyway, cool ideas here. Might have to experiment a bit more with my setup this weekend...assuming I can find enough old pennies lying around.
