I've noticed rainwater setups generally have fewer algae issues, probably because greywater tends to carry more nutrients from soaps and detergents. But if your rainwater storage gets sunlight exposure, algae can still pop up... shading tanks helps a lot. Have you considered tank placement yet?
Actually, I've found algae can still be a headache even with shaded tanks. Had mine tucked away under trees—thought I was good—but leaves and debris kept sneaking in, creating nutrients for algae growth. Mesh filters helped way more than shade alone.
You're right about mesh filters—they're often overlooked but can significantly reduce organic debris. Shade alone isn't foolproof, especially with trees nearby dropping leaves. Regular maintenance and fine mesh screens are key to keeping algae manageable in outdoor setups. Good call on that approach.
Good points on mesh filters, they definitely help, but let's not oversell them either. A few things to keep in mind:
- Mesh screens are great for leaves and larger debris, but fine particles and pollen still slip through. You'll still need periodic cleaning.
- Shade helps slow algae growth, but stagnant water—even shaded—can still get funky pretty quick.
- From experience, greywater setups tend to need more frequent checks than rainwater systems. Soap residues and hair can clog filters faster than you'd think...
Overall, both systems have their quirks—just gotta pick your maintenance battles.
"Soap residues and hair can clog filters faster than you'd think..."
Fair enough, but honestly, I've found rainwater systems can surprise you too. Last spring, my rain barrel got completely jammed up by pollen and fine dust—stuff I didn't even notice was accumulating. Greywater might have soap scum, sure, but at least you're expecting it. Rainwater debris sneaks up on you quietly... Both setups need vigilance, just different types of headaches.
