Nitrate or phosphate

[Jgill70]

I am looking to get hanna checkers for nitrate and phosphate. Right now I can only afford to get one, which one should I get first. My corals are starting to turn brown and I know my light is more than enough. I was thinking my nitrate or phosphates are high.

I would take a sample to a local store and have them test your water. From there buy whatever tester you need for the parameter that is off. If that’s not an option buy a cheap test kit just to identify what/if anything needs corrected.

Get both in something cheaper then upgrade in the future. If corals are declining you need to check both.

I would go with phosphate usually corals get brown when it’s high
But nitrate is also important get both if you can if not I will go with the phosphate

Hanna checkers are not required instrumentation. Get a sw master kit for $30, so you can monitor all of your parameters, until you can afford something else.

If you do decide to get the Phosphate, make sure it is the Phostpahte ULR. Nitrate get the Nitrate HR.
