High-tech: pH 6.0-6.5 (CO2 lowered), KH 3-5, GH 4-8, TDS 200-400, NO3 10-20, PO4 1-2, Fe 0.05-0.1 ppm.
Expert tips
- ✓pH 6.0-6.5 during lights-on
- ✓KH 3-5 (too much = pH rigidity)
- ✓GH 4-8 (soft to medium)
- ✓TDS 200-400
087🚰Water Source — RO vs Tap
Hard tap water (high KH) hinders CO2 efficiency and some plants. RO + remineralized water is ideal for high-tech, especially for soft-water species.
Expert tips
- ✓RO + GH Booster = perfect
- ✓Tap water if GH/KH low
- ✓Remineralize RO to GH 6, KH 3
- ✓Distilled water NOT recommended
088🐌Slow Growth Despite High-Tech
Root cause: CO2 too low, light too low, fert imbalance, too much trimming, or wrong water parameters. Systematic troubleshoot.
Expert tips
- ✓Check CO2 drop checker (lime green?)
- ✓Measure PAR if possible
- ✓Test NO3, PO4, Fe
- ✓Adjust one variable at a time
089🍂Yellow Leaves — Diagnosis
Yellow old leaves = N deficient. Yellow new leaves + green veins = Fe. Overall pale = overall deficient. Holes = K deficient.
Expert tips
- ✓Old leaves yellow: increase N
- ✓New leaves yellow + green veins: increase Fe
- ✓Leaf holes: increase K
- ✓Pale top growth: micros deficient
New plants melt during emergent→submerged transition. Crypt melt is famous. Roots stay alive; new submerged leaves regrow in 2-4 weeks.
Expert tips
- ✓Do NOT remove plant during melt
- ✓Keep CO2 + ferts dosed
- ✓Trim mushy leaves
- ✓Patience — regrowth in 2-4 weeks
Stems twist or stop growing at tips = calcium or boron deficiency. Stem bends + curl up = micronutrient imbalance.
Expert tips
- ✓Boron deficiency: twisted tips
- ✓Calcium deficiency: stunted growth
- ✓Add CSM+B or cal-mag supplement
- ✓Check GH (calcium source)
Fish at surface gasping, darting, or lethargic. Drop checker yellow. Emergency: turn off CO2, add airstone, 50% WC if needed.
Expert tips
- ✓Fish gasping: emergency off
- ✓Drop checker yellow: too much
- ✓Airstone + reduce injection
- ✓pH drop > 1.2 = stress on fish
093💀Fish Dying in High-Tech
Common causes: CO2 overdose, temp spike, stray voltage, pH swing, new plant pesticide. Systematic check when fish die.
Expert tips
- ✓Check CO2 (drop checker yellow?)
- ✓Check temp (heater stuck?)
- ✓Check new plants for pesticide
- ✓Water test: NH3, NO2, NO3
094🟢Sudden Algae Outbreak
Usually one of: CO2 drop, light too high, ammonia spike, nutrient spike. Find the change — what was different last week?
Expert tips
- ✓Trace recent changes (fert, light, CO2)
- ✓Check CO2 (tank running empty?)
- ✓Check ammonia (dead fish? over-feeding?)
- ✓Weekly WC flushes algae triggers
