didnt see this post ... would have call u instead.. anyway i did something more for my tank.
in my attempt to keep and propagate ric , i realise i have place them too clsely together which result in upward stretching behaviour despite under 150watt MH .
some ric were under the shadow of the other ric and growth were slowed.
adding 2 x T5 in the front allow the coverage of the lighting to be better but still the upward stretching behaviour show.
i believe they are telling mi they need more space. have already spread them further just now. while doing that , i saw a good natural split of ric florida in my tank . now my tank seem fuller . after the rescape i decided to try one more cynarina.
