nitrate

hi can anyone tell me the ideal nitrate level for a mix fish invert system . its holding steady at 20ppm is this to high?

 

For a FO tank, should be no more than 5ppm. For a RT no more than 10-15ppm. My tank is the same way, 20ppm Luna

 

its as high as u want it to go dont let it go over. personally i try to keep mine at 10pp any higher and it needs to have a water change. nirate is not good for inverts so id do a water change personally

 

I disagree - Fish aren't that sensitive to nitrates unless they are astonomically high as far as im aware.

 

yah its normally just the inverts that cant stand it. as long as ammonia and nitrite are both at 0 it shouldnt be an issue. thats what i have always gone by anway.

 

There are alot of corals that consume No3. I try to keep my No3's down b/c they promote algae growth/blooms. Luna

 

Take it from me... fish can survive along with inverts at 100ppm for more than two weeks straight... I've since gotten them under control but no one appears to have suffered ill affects.

thanks nitrite amonia are zero , i change 10% of the water every month , so will shrimps and crabs be ok with this nitrate level?

 

it should be fine. just dont let it get higher then that. once it does everything else always seems to go wrong too.
algae growth, the whole lot.

 

you can even change more if you want. dont be afraid to. i do 25% every week.
