Nitrate wont go down

i dont think that would do you any good in the tray, but perhaps submerged in the sump. if you add about 30# of rock (doesnt have to be live right away) then i should think that you would need nothing else once the rock becomes seeded. rock, sand and skimmer can handle all of your filtration needs. add carbon and phosban specifically if needed.

after removing the filter media the nitrates have dropped a bit i have carbon but i understand it is bad for coral. also dont have a skimmer yet saving for a Percision Marine, i hear they are one of the best and localy made.

[hammondegge]

yep, get the skimmer next. it will make a very big difference.

so CARBON IS BAD???????? FOR CORAL????????!!!!!!!!

[PeeperKeeper]

I had not heard that about carbon being bad for coral and I know lots of ppl with beautiful reef tanks who run carbon.

How is it bad? Removing too much from the water?

[Louie3]

i have carbon but i understand it is bad for coral.

Thats what that guy said. I'm just begining with corals and my first polyps where under carbon filtration for about 3 weeks
and just reccived alot more and i dont want them to die

No carbon is not bad for the coral. Carbon removes dissolved organic compounds (DOC). We usually have an excess of DOC i the tank as a result of feeding and fish waste. I sincerely doubt you could ever get your DOC level down far enough to result in a negative impact.

High DOC has some bad secondary impacts as well. It will cause a lower redox potential and can cause a bloom of cyano.

not bad

I HOPE carbon isn't bad. I've got something like 36 POUNDS on my tank...
