Sanjay, tank looks great!!!! I just picked up some tabling acros and hope the grow as fast as yours do. Time to replace bulbs and am debating on keeping the Reeflux 12Ks (seem more blue than the Radium 20k) or trying your Geismann 14Ks. I am running digital ballasts, one Lumatek and two that I am told are made by Lumenarc (I am told that Galaxy, Lumatek and Lumenarc are all made by the same mfgr.) What might your expert opinion be?
Personally, I do not like to change if things are going well. If you like the Blue look you will not be happy with the Giesmann 14Ks. They are a nice white bulb.
I do not know if these ballasts are made by the same manufacturers, but there is very little significant differences between the electronic ballasts as far as operation is concerned.
