Planting Planner
Catalog of commercially-available freshwater plants. Each plant is checked against your light level and most recent water reading — green / yellow / red.
Fish & Invert Health Check

During treatment — protect your bio-filter reference — tap to show
Removing carbon for meds + raised temp during Ich + fish that stop eating all stress your bio-filter. Ammonia spikes mid-treatment are common. Use this checklist whenever you medicate.
- Test NH₃ / NO₂ daily during the full treatment course — not just at the start.
- Dose Seachem Prime every 24 h (5 mL per 50 gal) for the duration. Detoxifies up to 1 ppm of either for the next 24–48 h without harming the meds.
- Carbon out before meds, back in AFTER the final dose + a 25–50% water change. Putting carbon back too early strips the medication.
- Raised temp for Ich (86°F) accelerates the parasite life cycle AND drops O₂. Add an air stone or raise the spray bar for surface agitation.
- Fish off food while sick? Cut feeding by 50–75% — reduces uneaten food rotting and ammonia load while bio-filter is stressed.
- Aquarium salt at 1 tsp per 5 gal helps Ich, supports gill function. SKIP if you have shrimp, snails, or scaleless fish (corys, loaches, plecos).
- If NH₃ spikes during treatment: 25–30% water change with dechlorinated water at the same temp. Re-dose the medication proportionally to the volume replaced.
Planted Tank
How we decide
- Not needed — low light + low-tech plants (Anubias, Java Fern, Crypts, Vals).
- Optional — medium light, mixed plants, you want faster growth and deeper color.
- Required — carpets (HC, Monte Carlo), red stems (Rotala, Ludwigia Super Red), or any high-light setup.

Dosing plan (Estimative Index)
Estimative Index baseline only. Adjust based on your plant load, growth rate, and water-test results. Macros (KNO₃ + KH₂PO₄) and micros (CSM+B) on alternating days.
Plant supplements — root tabs & liquid ferts
How to pick the right supplement for your setup
Shrimp Keeper
Drip-acclimation timer
Molt log
Watch for failed molts: opaque or white flesh on a shrimp’s tail/abdomen = muscular necrosis, a follow-on to a failed molt. It’s contagious. Isolate immediately, do a 30% water change, and verify GH 6–8 + calcium intake (Salty Shrimp Mineral GH+ or a calcium-rich vegetable like blanched zucchini).
Colony census
Health check reference
Tap a condition to see signs, cause, action, and prevention. Not a vet — a starting point.

Your data lives on this device only — nothing is sent anywhere. Use the tools below to back it up, move it between devices, or hand off to a spreadsheet.
Backup & restore
One file contains every tank, reading, task, stocking entry, light schedule, and setup-timeline checkbox. Save it anywhere safe — cloud drive, email-to-self, USB.
Spreadsheet export
Export a single tank’s readings to CSV — open in Excel, Google Sheets, Numbers, or anything that reads commas.
Single-tank backup (JSON)
Export ONE tank plus all of its readings, tasks, stock, planted state, shrimp state, QT history, cycling log, and light schedule. Useful for sharing a tank setup, archiving before deletion, or moving to another device.
Danger zone
Wipes all data on this device. Cannot be undone. Export a backup first.
Aquarium Care Suite · v120a
Add a tank

Help me pick a stocking
Answer a few quick questions about the feel you want. We'll match species from the 200-species catalog to your tank size and water chemistry.
Compatible with my stock
Filtering the 200-species catalog against your current residents — temperature overlap, pH overlap, temperament, fin-nip risk, school minimums, and remaining bioload.
