I do have a decent amount of algae that's why I was asking. I will have the money for the bulbs in 4 months. But not for the powerhead. One more question. Should I get a vortech mp10 (1500 gph
) or a koralia that's rated for 2200? The vortech has really awesome features and I was thinking of using it as a wave maker to move more detritus around. Which on????? Also, the vortechs flow is a lot more spread out......... So it would more more places around...... I'm thinking vortech. What about you? The vortech is about $60 more expensive though.
