Hanna HI744 Phosphate Ultra Low Range Question

[GoTakeANap]

I am a little confused and want to make sure I am not reading this checker the wrong way since it is a ultra low range checker. When I get a 0.02 on my checker, is that the 0.02 I am shooting for to keep sps or does it need to be 0.20 with this checker? I didn't know if the ultra low range breaks it down in a different range or not. Thank you

You mean the HI774 ULR Phosphate checker, right? If so, you're shooting for the range 0.05-0.10 with this checker. Many run this range or a tad higher. Targeting 0.02 is within the accuracy tolerance for the checker, so best to aim a little higher to be sure.

Good to know. At the moment it was at 0.22 last week. I added some Phosguard to get it back in check. Guessing my Fuge isn't keeping up anymore. I'll cut back on feeding bc that is the only thing it could be. Only feed frozen.

Cutting back on feeding your fish might actually cause harm for your corals. Some corals cannot use nitrate at all of nitrogen and those that can have to use extra energy in the 30-80% range to convert the nitrate back to ammonium. Also, the other types of phosphorous from fish waste are likely more used than orthophosphate (po4). I would not cut any feedings, but rather up the export if you are worried about po4 accumulating.

If your fuge has slowed down, divide your chateo and add some iron if you are not keeping up with water changes.

That's Awesome. I just listened to a podcast where Lou Ekus was explaining this.
