EXTRACTED KNOWLEDGE / HOW-TO FROM CONVERSATION

QUESTION / CONTEXT: What do you recommend i print aquarium items out of

1. For aquarium items, PETG is my first choice, especially with your Creator 5 Pro.
2. It’s a much better fit than standard PLA for parts that will stay submerged long-term.
3. | Material | Aquarium use | Recommendation | |. |. |. | | PETG | Submerged decorations, caves, holders, brackets | ⭐ Best overall | | ASA | Tank equipment, especially around UV/light | ⭐ Excellent, but harder to print | | PLA | Decorations/temporary parts | ⚠️ Usually okay short-term, not my first…
4. PETG handles constant water exposure well and is easy to scrub.
5. For anything the fish can rub against, round all edges and avoid tiny gaps where a fish could get trapped.
6. One important distinction: the base plastic may be suitable, but pigments/additives vary by filament manufacturer.
7. I would avoid mystery filament, metallic/glitter additives, antibacterial filament, glow-in-the-dark, and anything containing copper or other potentially leachable additives.
8. For prints such as caves, tunnels, plant anchors, filter guards, feeding rings, air-stone holders, or custom aquarium structures, I'd generally use 4 walls, 20–30% infill, and enough top/bottom layers to make a solid shell.
