I have a simple Dual-Malt porter I am getting ready to brew. It calls for 6.25# Maris Otter (3L) and 3.6875# Brown Malt (65L), 3.75gal mash water. My existing water profile is Alk 98, Bicarb 119, SO4 9, Cl 4, Na 28, Ca 9, Mg 4. Bru'n Water estimates pH at 5.18 with no dilution; dilution, of...

I have read the first few pages of this post, but not all, so I apologize upfront if I am asking what has already been covered; there's a few years of posts here. 1st of all, based on the initial water recommendations, I should be diluting my existing water profile of Alk 98 (Bicarb 119)...

flars, Didn't mean to be disrespectful. I just couldn't get this picture out of my head of trying to stir the capsule in the water.

Now that's funny! Of course, have to open the capsules and pour into water.

Ah yes, did answer my own question. The only way I can dissolve is to crush the salts against the side of the glass I am using. I think I'll use some out of another tube next time and see if they're the same. I don't have enough data points right now. Just seeing if someone else has had this...

I have some 4.0 and 7.0 Hydrion buffer capsules that I purchased in January of 2017. There are 5 bottles of 10 capsules of each buffer. There is no expiration date on the box or the bottles but I believe from another thread here that the 7.0 should be good for about 2 yrs and the 4.0 for 4...

day_trippr, I do like your idea of pre-testing, something I've become pretty anal about, especially after this last round. Great when everything is holding, maddening when you get a leak. And you have a lot more shut-offs than I do. Like you I've had plugs, swivels, QDs, and keg lids leak...

My first thought is that I have 10 shut-off/check valves so that would be over $150 to convert. 2nd thought is that if I have pressure to the regulator, I would have to cap or connect a QD to the unused lines because valve would be open. day-trippr tests his, but that just tells the condition...

Thanks for that input. Interesting, because the problem with the one regulator intermittently dropping in pressure was due to the bonnet not being tightened enough to the regulator body. However, in the whole process, I found the 2 shut-off/check valves on the regulators at the tank were both...

After leaving the system pressurized overnight (actually about 19 hours so far), this time the NADS regulator has dropped 14psi and the Taprite is holding steady, indicating that, as I originally believed, the NADS is faulty (probably a bad diaphram). I will replace the NADS when I receive the...

Well, now I'm really scratching my head. Just got the wye where it's connected to the regulator and the 2 valves under water. Not even a bubble. The other 3 regulators are and have been holding pressure thru this whole ordeal. In the last two or three hours since I repressurized, the old...

Yeh, the valves could be leaking. Shouldn't assume anything. Nothing surprises me any more. I'll go ahead and check them. I could do what you're doing and use a 2nd co2 bottle to force carbonate the kegs. What I did was put 2 regulators on the tank, one to feed the kegerator and one for...

If you look at the pic, the middle regulator has a wye with 2 valves, and a hose connected to one of the valves. Notice that both valves are closed, so this leak is between the regulator and the valves. Anyway, there is no keg attached to the QD. As a side note, in my experience QD's tend to...

My kegerator has 4 Taparite regulators fed (see 1st pic) from a tank outside of kegerator (see 2nd pic below). I have isolated a slow leak to the middle regulator (see pic) by pressurizing the system and then turning off the gas. At first I thought there wasn't really a leak and it was just the...

Of course, another aha moment. Do you think the plastic syringes I got at Walmart are adequate?

AJ, could you suggest what to use to measure small acid amounts. As I play around with the numbers, scaling down to say a half pound of malt in one case would require .073 ml lactic acid. Pushing that up to a pound isn't much easier. What I currently have is a couple of 1 ml syringes...

I am reminded of the old saying about physics advancing one funeral at a time, as the old guard doesn’t seem to be able to let go of their ideas about how the world ought to work in favor of how it actually does work, as shown by the evidence. That said, it is important to understand that we...

Ok, think I've got it. Keep me honest here. In the example above in wanting to move from 5.63 to 5.7. .07*40 = 2.8 mEq/kg protons to be removed. Since 1 mmol sodium bicarb absorbs 1 mEq protons, then 2.8*84=235.2 mg. SInce the attached graph is an image, I was originally looking for a...

AJ, I hope you're still monitoring this post. I've been out of pocket for a few days. I am good with calculating the amount of acid required to shift pH. Don't think I'll have any problems there. Probably going to put my full ignorance on display here; I am having a bit more difficulty...

AJ, so sorry you had to input twice. Been burned enough that I've gotten where I copy long posts before submitting for that reason. I can't tell you how helpful this was. I have a much better understanding of how it works now. I really appreciate you taking the time to explain. Couple of...
