Trisodium Phosphate measuring grams without a scale?

[Delatedlotus]

Just a couple quick questions.... How do I measure grams of Trisodium Phosphate without a gram scale? It is for Phosphate solution as I have lost all my Phosphates they moved out weeks ago in the middle of the night. And where can I get the best actual easy recipe to mix my own phosphate..? I know there must be a way to measure out grams besides eyeballing it? I am new to this all together, but I am learning from you all on this one for sure.. Thanks really

You don't - You buy a scale for $10 off Amazon.

You'll be using it for years.
You leave nothing to chance in this hobby.

I dunno…..I mean I know some old 80s party peeps that could eyeball a gram better than a digital scale!

Randy has some great info in the chemistry forum. He’s very detailed. I would search there

Just get a cheap one from Amazon that measures to tenths is fine. That's what I use.

I know he’s equated tea/tablespoons in posts in the past for things like his salinity test standard. Maybe post in there and see if he can help you out.

What is the purpose of this solution you need to make?

If it is for phosphate dosing to a reef aquarium, the exact concentration is not important at all, and I recommend using this calculator and the entry for phosphate from potassium phosphate. it is close enough and gives a recipe based on teaspoons.

You really are the Guru of Seawater I really have noticed that and do respect just that to the max..
You have helped so, so, many individuals in this hobby and most of all you are always there as well..!
You know ALL about the actual heart of this hobby where everything begins and can end as well.
I have to ask only because I don't really know or maybe I have no couth lol. What Is your field and depth of expertise in this hobby is it associated with your employment, line of work? I do apologize this, but I just
don't know so I am just asking....

And thanks again Randy really I am sure from all of us....

Oh yes lol, I just noticed in your post lol. My phosphates bottomed out for some time now (5 weeks), I dropped my NO3 down 20ppm, lost all phosphates. Then I then moved around about 210lbs+ extremely old base live rock out of the sand. Exposing a lot of white non-coraline covered rock ( very deep fine sand bed) And a real lot of it..! I thought maybe some PO would leach out nope it didn't, just a bit lol. maybe its the opposite and the exposed new non covered rock is sucking up phosphates..? I have dosed and dosed Neopos...lol Up and down, then repeat and repeat.. I thought to be huge doses = 20ml twice or three times a day a see-saw affect over and over. Dumped in about a 1/4 a bottle last evening! Test in 24 hours. But now I am in it for the long haul I guess? I want to switch to Trisodium Phosphate I believe it to be a better option. Is that rite..?
