HI tommowow im going to buy an seacolne 100 for my 55 gal reef its clean as an wisle but my nitrates are at 40 my pets seem to be ok though will the seaclone lower the nitrates much??
IMO, Seaclones are not worth their weight in plastic. I would save up a little more money and get a good skimmer. AquaC, ASM (if in sump), Octopus are all good brands.
For the nitrates, regular (weekly) 10-15% water changes can get those down.
