- Avoid extreme pH swings
- Use a reliable heater and thermometer
Maintaining Water Quality
Clean water helps plants absorb nutrients better. Regular water changes remove waste and toxins. Test water weekly to keep it healthy.
| Water Parameter | Recommended Level | Why It Matters |
|---|---|---|
| Ammonia (NH3) | 0 ppm | Highly toxic to plants and fish |
| Nitrite (NO2-) | 0 ppm | Poisonous, affects plant growth |
| Nitrate (NO3-) | < 20 ppm | Safe, but high levels cause algae |
| Water Hardness | 3-8 dGH | Supports nutrient absorption |
Filtration And Circulation
Setting up a fish tank with midground plants needs clean water. Filtration keeps water clear and safe for plants and fish.
Good water flow helps nutrients reach midground plants. Circulation also removes waste and stops dead spots.
Filter Types
There are many filters to choose from. Each type works in a different way to clean water. Choose one that fits your tank size and plants.
- Hang-on-back filters:Easy to install and good for small to medium tanks.
- Canister filters:Powerful and quiet. Best for larger tanks with more plants.
- Sponge filters:Gentle water flow and safe for small fish and shrimp.
