Specific product picks
What NOT to buy
- Miracle-Gro with additives / manure bombs.
- Strong canister flow day one.
- Sparse planting — Walstad needs density.
- Deep uncapped dirt.
Common mistakes
- Cloudy water panic → huge water changes.
- Stocking before plants settle.
- Too much light hours.
Why this shopping list
Walstad trades gadget spend for plant mass and substrate biology. Use stocking calculator lightly — dirted tanks prefer sparse livestock early.
What fits this setup
- After weeks of stability: shrimp or few small fish.
- Avoid digging fish that destroy the cap.
