PE = happy SPS?

[mrhasan]

Well since I have recently got into SPS; I am experimenting with my level of lighting. I am putting acros on the top and did not see any PE yet (put them in yesterday). I have put a monti cap a bit higher than the bottom and its growing crazy. I also have digitatas placed a little lower than middle and they have full PE. Does that mean atleast the digitatas are happy with the level and the flow?

I am waiting on the acros PE since I heard that it takes days for them to PE.

20 gallon long with 12" high and 2 T5HO lights (10,000k + actinic) 30" fixture resting around 3" above water level. I am getting crazy growth on monti cap (better than mushrooms LOL).

Advice and suggestions please
