Yeah, part of the reason I dont run carbon unless I need to. Too expensive and it only lasts a few weeks. At least with the biopellets they are good for at least 6 months. lol

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

I've heard of about how biopellets will cause drops in alk though.

I run pellets. But I constantly dose, so I haven't seen a alk drop. I still think it's a safe and easy way to increase available carbon. But that is a bit different than running carbon filtration. The pellets directly feed the bacteria we all depend on in the live rock and elsewhere. Carbon filtration, to me, is really about removing both dissolved and gaseous toxins from the water. In a mixed coral tank, it can be indispensable to remove combating coral toxins from the water. Like in mine, where I have soft, LPS and SPS growing next to each other. When my carbon wears low, I can see the divisional lines between corals widen a.bit as they get more toxic to each other. But I may be insane. I also use purigen to polish the water of those pesky last bit of phosphates.

How about a denitrator setup? I know the basic differences between them and biopellets but at the end of the day which would be better? The denitrators are a bit more money and require a twist everyday but is it overly better than the biopellets?

ANyone?

Since I am still online, I will throw in my two cents. Excess nitrate products can be exported by live rock, converting to nitrogen gas, denitrators, or algae scrubbers. Everyone uses live rock as stage one, but as you have noted, with a heavily stocked tank, nitrates can build up. Most water exchange programs keep them under control, but I don't do massive water exchanges. So I went the natural way and grow beds of harvestable algaes. I put my nitrates into the local landfill. It is natural, stable and pretty easy to setup with a bit of room. But I also boost the bacteria in the live rock with bio pellets. Both work together and support each other.

Thanks Greg, appreciate your time. If I wanted to not go with an algae scrubber and fields of macro, which would you chose, denitrator or biopellets? I want to get away from the 50g water changes and was hoping i could add something equipment wise that would help with that goal. I of course dont want to replace water changes, but want to add something can help the tank overall.

I tried running carbon and gfo at one point but didnt see any great improvement so stopped. I do know you cant run biopellets and another media in a twin canister, they need to be separate.

Since this is my last big tank, reef anyways, i want to do as much as I can right the first time. I dont wanna be fiddling with equipment forever. lol I have the available credit right now so its as good time as any to get what I need/want.
Is the added expense of a denitrator actually worth it in camparison to pellets? Hoping some user can chime in and share.

Thanks all!
