LPS with low nitrates

[chinita]

I understand that most LPS likes water with high nutriets. I have 20ppm nitrates and .25 phosphates as of now and I'm planning to buy a denitrator and phosphate reactor. My LPS and clams are doing fine, but will they still survive if it happens that my nitrates and phosphates decreases to not so ideal level for them? My tank is now running more than a year now.

20ppm nitrates will not kill them but it is not recommended. High nitrate levels can cause stress to the corals and inhibit their growth due to the imbalance between the growth of zooxanthallae with the high dissolved nutrients. Therefore, for LPS to do well, nitrates and phosphates level should be as close to 0 as possible.
