Hi all. I am new to this forum but have done so much reading over the last few months having decided to try a planted aquarium properly. I was prompted to take a step further and sign up today having read Rob P's comments about the rim of his Roma and accommodating light systems. I have a Fluval Vicenza 180 (3ft and 150 litrs) and am looking to buy LED lighting. I have at the moment Guiesmann Midday x1 and aquaflora x 1 24 watts each 2 months old (I know that is old school now) I painted the back and sides of my tank black and really like the look of it but I am wondering if I have compromised the light efficiency. The t5 tubes are only 22'' long so I am finding that plants in back corners are struggling. I tried first Eustralis stellata hefty but I have had to move what was left after 2 weeks , to the centre. Easier plants seem to cope but my real question is whether anyone has seen in use the Fluval aqualife and plant high performance LED which I believe came out this year? (Fluval clip on U Tube) It has 54 LED 2,580 lumens, 5,952 Lux 5,200K. My problem is that I would have to remove existing top and sit this over. It has extending arms, but to fit my tank I would need the 2nd size ie 36''. I just hope this would not be too much light as I do not want to suspend it from the ceiling. Any advice would be greatfully received. You all seem so knowlegable and I have so much to learn! Thanks so much in advance.
