I've been very pleased with my Deltec MCE600 for that size tank. Being in
the UK the availability of models and maunufacturers is a bit different from
other parts of the world, I don't know how far Deltec travel outside of
Europe (if indeed you are outside of Europe).

Peter,
Ammonia is the start of the Nitrate chain, so long as you
have ammonia present that indicates that your filtration system is not
functioning correctly, if you are relying on live rock (the best
method) then either you don't have enough, or you have been sold none
live rock, or you have little or no water flow through and around your
rock work, or if your tank is a new set-up it has not yet gone through
the nitrogen cycle.
regards.

I have 75 lbs of LR in a 75 gal tank. I think my problem is lack of
crculation around the rock itself. I just moved one of the power heads and
now I noticed the oil slick film at the top of the tank is no longer there.
The tank is over a2 years old but i recently added 25 lbs of LR a few months
ago..

Hi Peter,
Your ammonia is coming from the new live rock it is
causing a 'mini' cycle I hope!, not a major one.

Hi Rjag,
A protein skimmer will not remove nitrates, you have to
eliminate the source of the nitrates, usualy biofiltration - wet & dry
filters, canister filters, bio wheels, your water supply, over feeding.
The best form of filtration for a salt-water tank is live rock and a
DSB plus a good protein skimmer full stop. The best method of
controlling nitrates and other unwanted neutriants is a deep sand bed
from 4" to 6" a sump/ refugium is a good place to put it, anaerobic
bacteria in the lower part of the DSB (deep sand bed) will convert the
unwanted bacteria to nitrogen which will escape harmlessly to the
atmosphere.
Prizm skimmers have a very poor reputation !!.
regards,
unclenorm
