[thomas1102]

i am in the prosess of a 125 aga(72x18x22) and am looking at a 3 bulb retroft w 2 t4 actinic. if i can get my hands on a 150wx3 de retro than that is what i plan to do, but if i cant will 175 be fine and if i do do 175 where will croceas and maximas need to be placed to thrive??

i think for a 18 inch deep tank a 175 w would be fine for them

Just be sure to place the clams high up in the rockwork directly under a bulb
