Hi there, One of the most common questions I get is: “My water has gone a bit green — should I be worried?” Short answer: no. Green water usually means algae. And algae are just another living creature in the ecosystem. They’re not harming your fish. They’re not blocking your plants. They’re doing what living things do in water with light and nutrients. Now, if your water is brown and murky — thick with suspended solids — that’s different. That usually points to overfeeding, too many fish for the system size, or waste that isn’t settling properly. Worth looking into. But here’s where most people go wrong: they see anything less than crystal-clear water and immediately start adding filters, UV sterilisers, extra pumps… and suddenly the system is burning through electricity to solve a problem that doesn’t exist. A well-designed aquaponics system doesn’t need heavy filtration. It finds its own balance. A few solids in the water are completely normal — and far better than an over-engineered setup that consumes energy fighting nature instead of working with it. That’s one of the core ideas behind how I design systems: let the biology do the work, keep the technology minimal, and stop trying to make your pond look like a swimming pool. I go deeper into this in my water quality guide — what to actually watch for, what to ignore, and how to design a system that stays balanced naturally: Read the water quality guide Jonathan P.S.
