Phosphates !!

[Nate2005]

I lost my phosphate api color chart but I'm pretty sure that's 10ppm[emoji51]I have lps and soft corals in my nano reef ,this could be why a lot of them aren't opening up,even my new gsp and Xenia aren't opening .

What do I do ,could all of my coral die

Phosphates !!

Looks like between 0.5-1.0, I can't see clearly though...

Maybe a water change is needed.

Not the right color chart but maybe this is better

Looks like .50, run some phosguard.

On another note, if you could please shrink your pictures down a bit before posting? The huge pictures make it difficult to view the text. Thanks.

I like API for Alk, pH and calcium but when comparing API's phosphate to other test kits like ELos and Nyos it's been inconsitant or at least difficult to read. I would recomend getting a differnt test kit. When using Elos or Nyos to test higher levels you can use 2 - 4 parts of distilled water to 1 part of tank water then multiply by whatever was used. Keep in mind corals can become phosphate deficient if it's dropped to low. Here's a video and links to research on corals and phosphate:
