*EDIT* I'm leaving what I wrote earlier, but it doesn't look like it's the same "Hydroplex". It should be, as the Ruby Reef version says it's trademarked, but there's no chemical information I can find for it. The Hydroplex I found the MSDS for is a plant supplement, so the MSDS info makes sense. The Ruby Reef HP might be some sanitizer or antibiotic, no idea. Or it could be a scam.
I've never heard of it before. So I looked up the MSDS for it.
potassium phosphate, potassium nitrate, and magnesium nitrate
KH2PO4, KNO3, and MG(NO3)2
All of which are used as fertilizers for planted tanks. The first two, anybody who doses EI uses. The third, less common but still not rare, is a Magnesium source. All three are sold at GLA, and together they cover your N,P,K, requirements and add some MG.
So they're fertilization chems that Hydroplex claims can be used to keep fish healthy, no mention of plants. Interesting.
