My phosphate

[Kawasaki213]

Ok going to look at it now, I check my tss water it's 0, going to change the filters running 17 particles out

This is better.

Which rodi do you have?

This is from Hanna instruments:

There are some key differences between the two checkers. The HI 713 is designed for most water applications, while the HI 736 is a marine checker, which is designed for use with saline water. The HI 713 gives results in ppm phosphate, and the HI 736 gives results in ppb phosphorus; the HI 736 is therefore more sensitive because it can detect much lower concentrations. Regardless of the checker units, the results can easily be converted to the desired units by multiplying by a correction factor.

To convert from phosphate to phosphorus, divide results by 3.066, and to convert from ppm to ppb, multiply by 1000. To convert from phosphorus to phosphate, multiply results by 3.066, and to convert from ppb to ppm, divide by 1000. In summary, when deciding which checker is right for your application, consider (1) the salinity of the water, and (2) the expected concentration range, remembering to convert units if necessary.

Its is fine to combine gfo and carbon. To do that though you want it tightly packed so they can't grind each other down and you want it mixed thoroughly together. Since carbon doesn't last all the long before starting to clog ( 7-14 days ) that means you add lower amounts of gfo and you change it out more often. For my 180g tank. 1 cup of rox .8 carbon for a week, when phosphates are a little high I add 1 tablespoon of GFO ( mixed together ) and tightly packed. Works just fine this way. If you choose not to buy a second reactor. Just use less and change more often.

My personal opinion on phosphates, if corals are looking good and no algae issues then I wouldn't really worry about it. There are plenty of tank examples of high phosphate yet are amazing. Through observation I have found my tank does best when phosphates hover around .06ppm. Attempting to maintain the so called ideal level of .02-.03ppm range by corals start to look more pastel which I don't prefer.

I use a reactor with Phosguard that seems to help keep the phosphates down. I recommend the Hanna 76 as well. I check the phos and alk almost daily as they are quite quick and easy to use.

Do you guys have a good chart to go by, their seems to be a lot of them out there and I always question my self, and idea how to lower it, I am running a carbon and phosphate reactor mixed together. "Watch a bulk reef supply video "
I have zoas, bubble tips ,max clam, fish ect, wanting to start sps soon trying to get my 80 gallon set up just right.

For your information if I am seeing it right your GFO in the reactor is not tumbling which is not good. You should put the carbon first and then add GFO and observe if its tumbling or not. Otherwise it is of no use.
