In this post, I will share about my Arowana tank covers which are safer, lightweight and do not block light and ventilation.
My criteria for tank covers are slightly more demanding than those for typical fish-only tanks as my tank is planted. Of course, the main reason for tank covers is to prevent our precious fish from jumping out. In addition, for planted tank purposes, I need to:
- Minimise light blockage as the plants need light to grow well.
- Minimise heat retention. Bright lights produce more heat, plus plants generally do better at lower temperatures (preferably 28 celsius and lower).
- Maximise ventilation for evaporation. Evaporation helps water to lose some heat and not build up excessively under the lights.
