The plants in my tank are growing well even the moss has started to show new growth. The problem is the new growth on my red plants is green ...... I thought that reds going green was down to insufficient light but from the par charts I have looked at I should have high light or at least mid-high. I have a juwel rio 180 so 2x 45w hi-lite (guessing their version of ho bulbs) with reflectors and they sit like 2/3 inches off water. The tank is around 45cm deep. The tank is co2 injected has a soil base capped by silver sand and also dose EI. Any ideas?
