Seachem phosguard???

[Chiefmaster30]

How much seachem phosguard should I use in my media reactor? I have a 120 gallon tank with a 30 gallon sump!

It would say in the bottle how many grams to a certain amount of gallons of water, you can calculate it with that.

Here are Seachem's instructions;

Use 85 mL (1/3 cup) for every 200 L (50 US gallons) saltwater.

That would mean that you need 1 cup for your 150g

Hmm. Thanks for making me realize I've been short dosing everything

 

[Chiefmaster30]

Thanks!

Not necessarily. The instructions, as for all additives, medications, and media, are for actual water volume in the system, not tank size plus sump size. Displacement for rocks, sand, etc., must be taken into consideration.

Yeah, but i think in his case he should be good with that.

I see that you live in Georgia, Seachem's headquarters. Do you happen to work for Seachem?

When starting something new (additive; media; etc), I always go with less than the recommended amount to see how everything reacts. If you have coral, you might not want to dramatically reduce phosphate all at once. I run phosguard in my reef in a reactor with carbon. I purposefully use less than is called for because I want some phosphates, just not a lot.
