Water Filtration Breakthrough, Hydrophobic Pot Discovery & Electronics Architecture

# Two Breakthroughs in One Day Some days the project hands you a crisis and a solution in the same afternoon. **The water mystery.** Fresh water went into the fish tank, looked fine at first, then turned grey and cloudy over a few hours. The fish retreated to the bottom — a clear stress signal. After flushing the system with clean water, I ordered two 20-micron drinking water filters and tried again the next day with pre-filtered water. Result: crystal clear within an hour, fish completely relaxed. The new water source carries fine particulates that need one pass through a filter. Problem solved, and now there's a reliable protocol for any future top-ups. **The hydrophobic pot problem.** One of the fabric grow pots placed on the sand layer came up completely dry the next morning. Not just a little dry — bone dry. The culprit turned out to be the fabric itself: when it dries out fully, it goes *hydrophobic* — it actually repels water rather than absorbing it. The wicking action can't start because moisture bounces off instead of soaking in. The fix is beautifully simple: soak every new fabric pot in water for about an hour before placing it on the sand. That pre-soaking breaks the water-repellent barrier and lets wicking begin immediately. One small ritual that unlocks the whole system. Between these two discoveries, the wicking bed is dialed in in ways it wasn't a week ago. Every problem teaches you something the instructions never mentioned — because nobody wrote them down yet.
