1. Weekly Care Protocol
Algae Control: Use a soft-bristle toothbrush to remove diatoms from porous rocks (e.g., lava stone). For stubborn growth, apply spot treatment with 3% hydrogen peroxide (5-minute exposure before rinsing).
Water Testing: Monitor pH/GH weekly with liquid test kits. Limestone-containing setups may require buffering (e.g., almond leaves for pH stabilization).
2. Structural Integrity Checks
Rock Stability: Inspect bonded joints monthly. Reapply aquarium-safe epoxy if gaps appear, especially in cichlid tanks where digging behavior occurs.
Substrate Gaps: Vacuum detritus trapped under stones during 25% water changes to prevent anaerobic pockets.
3. Biological Balance Maintenance
Biofilm Management: Preserve beneficial bacterial colonies on stones by limiting scrubbing to visibly slimy areas.
Silicate Control: Replace 20% of filter media monthly if using silicate-absorbing resins to combat diatom blooms.
4. Seasonal Adjustments
Summer Precautions: Increase oxygenation during hot months as decomposing waste accelerates. Position air stones near rock piles.
Winter Lighting: Reduce photoperiod by 1 hour to compensate for slower plant growth around stone features.
5. Emergency Response
Ammonia Spikes: Immediately remove affected stones for peroxide soaking if detritus release is suspected. Dose with nitrifying bacteria supplements.
Cracked Stones: Quarantine fractured limestone to prevent pH swings; replace with pre-soaked alternatives.
