Im running the SCP-90 in a IM40 Long (36") and was blowing sand so I flipped it and pointed it up and seems to be perfect now creating a nice wave and good flow across the whole tank.So i returned that pump and went with the SCP-90 and a SLW-20. I'll be able to test both in the tank sunday to see what type of whirlpool i can create![]()
Awesome progress, following along!
but no bacteria
as for the AF sand i am not sure yet, other than looks it is hard to messure how well it does until later down the road. But reviews from others have been great and I love the look
don't give up, your journey is just beginning
