How to measure phosphate resin

My ferric oxide is coming in the mail today. I head that you have 1 gram of ferric oxide per gallon (correct me if im wrong) and i was wondering how i should weigh that. I dont have a "letter" scale ;D so is there an easier way? teaspoons? tablespoons?

 

anyone??? If you dont get what im saying, like is there a system instead of grams per gallon its tablespoons per gallon for instance (just a random, inaccurate example)

 

I don't know offhand, I would go to Target and get a kitchen scale, they're like $10-20 or something cheap like that, then just measure a quarter cup and divide that down to find out approximately how many grams are in a tablespoon etc.

Scales are always useful to have around anyway, I probably should take my own advice eventually.

 

I get my GFO from Bulk Reef Supply and I think they recommend 1 tablespoon per 5 gal.

 

ok thanks i did that. Now theres a sponge and a plastic thing at the bottom right before the resin and then theres a sponge and a plastic thing that i put on the top. How far away should that one be from the resin? on it? 1"?

thanks,
ryan

 

Just put some in th reactor I'd use at least a 1/4 cup or e a 1/2 cup if you have a normal sized reactor and forget about it just make sure you have enough water flow through there bed to keep it in a fluidized state on the top like a floating waving motion and let it ride I have had mine running now for over 8 months still no PO4 can be detected and until I can I won't recharge it . No such thing as a target amount all you have to do is keep it in a fluid motion and not overly aggressive as that can beat it up and break it into a rust mess .

The small amounts that they recommend you to use is a doubled edged sword It will break down and not enough media bed to totally remove the PO4 and you will blast through it much faster . Same with carbon if you
try to analyze and research its use and amounts and you will get a million answers and all will be different.. some say a Oz per this many gals others will say a cup per 100 gals . I use the cup per 100 gals myself or more even .
