Phosphate rx

[Blade*13]

Who all with Nano has used phosphate rx? I have a innovative marine 20g that is having a gha issue. I've been doing water changes, every other day to try to get rid of this stuff and just won't seem to go away. I'm not running a skimmer but do have a algae reactor, but it seems the gha is out competing the macro algae. Any help would be greatly appreciated

What are your tank parameters?

 

[Blade*13]

Which ones do you want? Nitrate and phosphate and what else?

 

[Blade*13]

Ph= 8.0
Phosphate= .1
Nitrite= 0
Nitrate= 5
Alk= 8.4
Cal= 420
Mag= 1200

Could the low mag cause the algae?

No experience with Phosphate Rx but I do use GFO in the back compartment of my Evo and it does a pretty good job of keeping my phosphates down. But ultimately getting a little tuxedo urchin was what solved my GHA issue. He mowed through all of it in my tank in about a week and a half and now I feed him nori to keep him happy. I understand not all of them will eat GHA, but mine is an absolute beast.

Chemipure Elite and Purigen. I have 0 NO3 and 0 PO4

Dosed 60 drops in my tank last night. I actually under dosed the total volume of water I have. Took a reading this morning. The Hanna ulr registered 1, which when entering the reading into fusion it automatically converts the result into ppm, which is 0. So I guess my po4 is just barely detectable. This stuff works. Nothing in the tank even noticed. All is good. I guess this product get a thumbs up from me!
