sps and nitrate

[nangle2323]

is a nitrate of 20 ppm to high to keep sps corals kinda new to keeping corals but i have a 125 gallon with a 45 sump and was wondering how high the nitrate levels can be for ur corals to be ok any advice will be greatly appreciated

20 is going to be pretty hard on most SPS.

I'd shoot for 7 or lower.

I have mind at 20 with sps and they are doing good.... but trying to lower it

They won't do well for very long and they will eventually all be brown.

You will likely have poor colors with a nitrate that high but you will be able to keep them.

My nitrate has been 40-50 for about 10 months. Acros and milles still have nice colors, but no growth. Some frags died off with this level as well. I think less than 10 is best for most SPS corals.

Below 10 for good growth and colour.

With measuring high levels, Salifert is good. For lower levels, less than 40 down to zero, I like Lamotte and have used it for about 10 years now.
