Reproduction

Reproduction Method:

Comments

Background plant, can get very tall if not trimmed and even grow out of the water.  Leaves that grow out of the water are thicker, but have the same general shape.  Sodium bicarbonate (Baking Soda) added to raise ph.  One level tsp added daily after water changes until pH of 7.0 to 7.2 is maintained.  One tsp. will also raise the Total Dissolved Solids (TDS) or General Hardness (GH) about 10 ppm per 40 gallons ( 152 l).  One part SeaChem's Flourish is mixed with 19 parts aquarium water and then injected into the sand bed every 3 inches (7.5 cm) every other month.  Substrate used is #60 sand (very small fine grain natural sand).
