Chemi-pure

[o2bnh20]

Do many people out there use the product. Along with my skimmer I'm tring to get rid of DOC. They claim to leave it in the tank for 4-6 months. Is this a good thing to do? Wouldn't it absorb the good elements too?

[Randy Holmes-Farley]

I'm not sure exactly what chemi pure really is. Nevertheless, I can't see leaving it in that long. IMO, carbon is a good choice for DOC removal, along with skimming.

Chemi-Pure is activated carbon and resins. IMHO the resins don't do all that much.

IIRC it is the Boyd stuff and is a white powder.

Correction: I confused it with Chemi-clean.

Thanks, guys.

I'd treat it just like carbon, and leave it in for 2-4 weeks.

[o2bnh20]

2-4 weeks, or days?

[Randy Holmes-Farley]

2-4 weeks is about how long I leave carbon in the water.

Okay. I'm also using a seachem product phosguard to help with phosphates and silica. Is it alright to use this and carbon at the same time?

[Randy Holmes-Farley]

Yes, it is OK to use them at the same time, although I do not generally recommend aluminum-based phosphate binders due to the possible release of aluminum:

Thanks for the link, I'll read up on it. I think I need to reduce the phosphates though. I use ro/di water. What else can I do?

[Randy Holmes-Farley]

There are many ways to reduce phosphate. Skimming, growing macroalgae, iron-based media, etc.

I'll read the link. I have a good skimmer and I grow macroalgae. Could you name an iron based product?

[Randy Holmes-Farley]

Could you name an iron based product?

Phosban, Rowaphos, or Phosphate Killer.
