millennium 3000 wet/dry bio filter

I had a queation about my millennium 3000 wet/dry bio filter..hang on the back type..It seems to have done a good job in the past but I had recently got into coral and someone had told me to remove the carbon filter and just run it with the bio...does that sound about right?..thx

Actually, that sounds exactly wrong. With corals, the purpose of filtration is to remove organic waste without introducing Nitrate into the system. This can not be accomplished with biological filtration. You need to be running a protein skimmer as your only source of filtration on a reef aquarium. In fact, this has become such a successful method of maintaining a saltwater aquarium, that it is also the generally accepted way to run a fish only aquarium.

The advice you were given is perfectly incorrect. If you did exactly the opposite of what you were told, and removed the biological filter and increased carbon usage, then you would have at least some basic form of organic waste removal. This, however, would be very inadequate compared to a skimmer.

Let us know the details of your setup and future plans. We can make some pretty simple suggestions to get you on the right track.

ymh, all--- mechanical filtration used for saltwater aquaria will at some point in time turn into nitrate factories. they are not a good way to go. liverock, live sand, (aragonite) and a skimmer in a well cycled tank will be all that you need. the bios will take care of cleaning & nutrient management, & the skimmer with removal of contaminents. there are max & min's of sand depth and amount of liverock and there are charts to follow, so as to provide the best possable filtration & denitrification.

It is almost impossable to run a reef tank without biological filtration via liverock and live substrate. a skimmer can in no way keep a tank with fish clean unless it is huge in dimension. add coral to the scene and you end up with a cesspool.skimmers do not remove any meaningful amount of no3. a skimmers main job is to remove protein, it can and will remove some good elements (trace) as does charcoal."the proceding items are not proteins"

organic waste can be allowed to decompose or turned over to a cleanup crew, (snails,hermit crabs, various worms,copopods, gammarus, other shrimp, even the coral themselves. when organics decompose they give off ammonia, this ammonia is broken down by bios into nitrite, then another class of bios change the nitrite to nitrate, then the nitrate is changed into nitrogen and what nitrogen does not escape the tank will start the denitrification process all over again.almost all nitrate is reduced to nitrogen in the sand bed (substrate) an excess of nitrate can be removed thru water changes or increasing the bio population. not by skimming.

Exactly. I do not see a disagreement here. This is perfect advice. Ruge - i think you have misread something i have posted, because we appear to agree on the basics of marine aquarium care.

actually, a well maintained mechanical filter "NOTE" well maintained, will assist greatly in picking up the larger particles of fish excrement, even if there are some clean up animals present.

There is actually a similar thread in the works here:
29 gallon reef project (Pics included) - MyFishTank.Net Freshwater Saltwater Aquarium Fish Forum

Just to show yet another online community supporting this concept. It is widespread.
