@equinox - i did keep the original lighting...
from left to right:
1. arcadia plant pro 39w 7400k
2. juwel day 54w 9000k
3. juwel nature 54w 4100k
4. arcadia plant pro 39w 7400k
the two 39w are noticeably brighter than the 54w, i then switched the two 39w for four 54w still keeping the juwel tubes, so i had four arcadias and two juwels.
i have just got a new ballast and two more arcadias so when i re-setup my tank i will be using only the six arcadias..
my dosing regime was something like this:
sunday day1) prune, preen, clean glass inside, 50% or more water change, vac/sub, 1/2 tsp kno3, 1/8 ish tsp kh2po4, 1/2 tsp equilibrium, 1/2 tsp dolomite and clean glass on outside
