I am growing Hygro Poly in my 80L/21G low light excel based tank, and am having great success in keeping this plant. Given the shortage of low light/lower CO2 planting options, I am having trouble planting around the Hygro. At the moment I have it set against Java Fern, but the Java Fern is causing the Hygro to look cramped. Please critique! All suggestions welcome. Here's what I have so far (Hygro back left of tank) Thanks in advance! Regards, Glenn.
