Hi... New-be here and I have read in several posts that people say they dont use the Plastic Bio rings that come with the Nano cube but replace it with something better.. But I am unclear what this is.. Could someone please explain..
if you're using LR, that will act as your filtration/media. you can use the plastic rings/balls but overtime they will act as a nitrate factory. i say ditch them before you get started. also, you can use a chemipure or purigen to aid in controls your parameters.
I have an aquapod and I put small chunks of live rock in the back of the tank instead of bioballs. I was advised to take the sponge out of the first chamber, but when I did that, the tank got real cloudy, real fast.
So for now, the sponge stays, and when I do my water changes, I take the sponge out and clean it off in the water I take out of the tank, by submerging it and squeezing it out. So far so good. . .
Ok... I see what you are saying now.... Even the Nano Cube manual states you dont need the Bio-Rings if you have 1lbs of LR per Gal...
Is it ok to still use the Bio-Rings??? Only reason I ask is I think I am only going to put about 20 lbs of LR in my Nano 28... Reason being I have a couple of nice pieices of fake Coral on fake LR I want to put in there too so dont think I can hold 28 lbs of LR...
they recommend 1.5-2 lbs of LR for every gallon of water.
i have 40lbs in my 29g BIOCUBE and it looks great and have never had any filtration problems. keep in mind after displacement due to ROCK/SAND/SKIMMER etc... the total water volume will be alot less.
