Why you'll love it
- ✅ Complete natural base—soil + supplement for a self-sustaining root zone
- ✅ Sized for bigger tanks (40–75 gal)
- ✅ Healthy plants & fish—stable water chemistry without chemicals
- ✅ Safe for fish, shrimp, snails, and plants
- ✅ Low-tech friendly—deep-substrate foundations that last
How to use
- Spread about 1 inch of soil across the tank bottom.
- Cap with ~2 inches of pool filter sand (do not rinse the soil).
- Plant heavily on day one—stems, swords, crypts; mount rhizomes (Anubias) on wood/rock.
- Fill slowly, run a sponge filter, and avoid disturbing the cap.
Sizing tips: For tanks larger than 75 gal, use two Large bags or one Large + one Small to maintain a full 1-inch base. If coverage is a little shy of 1 inch, you can mix in a cup of plain peat or potting soil and blend well.
What's included
- • Aqua Preta Complete Soil (large bag)
- • Father Fish Supplement pre-matched for this size
Father Fish tip
A precise 1 inch soil base capped with 2 inches sand is the sweet spot—no chemicals, no CO2, just biology doing the work.
