You may not need as much. The 45 has a canister filter. I have the DSB and
lr to counter act the nitrates. Also, there are about 6 creatures in that
tank that like to poop it up.

The biocube is pretty stable. I have a skimmer and more lr in the false
back.

They look good cause I check the water every 24 hours.

If I had yours I'd put another 150 lbs of lr in..Here, that's about $800
with tax and it is getting hard to find.

Heh, dont think I'll be adding that much...though the LFS near me
actually gets it in plentiful amounts. I basically go there every time
he is expecting a shipment and will just be hand picking the little
chunks ro fill out my tank. I don't need it for the filtration as much
at this point, but more for aquascaping purposes...filling in the gaps,
making more places to put corals etc...and of course the extra
filtration can't hurt either
