thats the point, what are the pros and cons of both that you see...
what about the cubes need to be changed?
i have them running on tanks ranging from 20L to 3500L
Ok NP PelletsPlease do air your views... That way all members will gain a better understanding of the product.
Pros:
Best filtration method I have ever used
No worry about Redfield ratio (provided it is your only filtration used)
Cons:
Personally I see none but let me discuss what others see as cons
Need a battery back up in case of power outage, Not a con because the first thing any reefer should buy for his tank is a battery back up IMO
Needs a skimmer rated for twice the tank volume, not a con because so many people in SA particularly under skim their tanks, so a big skimmer can do nothing but good
Needs a reactor, not a con because personally I like the neat and tidiness it brings to my sump area as a pose to salt creep from airstones, a reactor can also be used externally therefore also being very space saving.
Cubes
Personally I have never used them and never will until like I said a few things about them change but I really don't feel like being banned today so will just leave it there
