Okay, after several failed attempts at making my own, i am just going to buy the stuff

The places here in Garland don't sell the stuff....anybody have any sources or willing to sell me some of theirs?

Is all you need a 4dKH solution? I can whip that up for you no problem and bring it to the next meeting. I use RO/DI water and baking soda with a mass scale to set my tank to 5dkH exactly. Is RO/DI and baking soda acceptable for making it?

Orlando is a great guy to deal with though. I highly recommend GLA.

Yep, that's all I need. The solution Orlando has is out of stock and the one I made just doesn't cut it..maybe its my scale.

If you can spare a few drops, that's really all I need. Thanks for the offer!

I got mine at Green leaf for 6 bucks plus shipping. It comes in a reference and indicator. The indicator is already pre-mixed all you have to do is put in the drop checker. They shipped it really fast. I got it in 2 days....

Sure..if you don't mind.

I only needed the 4dkh and not the other solution, so I didnt purchase that package.

I appreciate your help!

No prob. I think I have come up with a new way of making this stuff that will make it much easier for ANYONE to make it. No need for gallons of RO/DI water or sequential dilutions. And way more accurate, too.

I'll be using a small volume of water (maybe a cup) and a TDS meter. With RO/DI water, we can just add pinch by pinch of NaHCO3. When the TDS meter hits the right PPM value, we have the exact solution. TDS meter will be much more accurate than cheap scales and dilutions. This is how I set my 50G tank to exactly 5dkH when I set it up, just on a larger scale.

If we were using calcium carbonate, it would be 71.43ppm for an exact 4dKH solution. I have to do the math to figure out what the ppm reading should be when using sodium bicarbonate (baking soda). I think it should be 120ppm exactly, but I need someone to check my math.

hehehe....that's beyond me but thanks so much for whipping up a batch. Sounds so easy with your meter...and much better as you say than making the large batches with scales, etc.
