Will the ph of my compost tea buffer back to normal? Because i put a cup in and got it to 10ph
Since Hydrated Lime is a Inorganic Substance (Calcium Hydroxide)

Pretty much, yes.
And a cup!?!?? Hydrated lime is usually measured out in teaspoons and even more usually, just plain avoided, because it's nasty shit.

Can you please explain how hydrated lime kills beneficial microbes???? Unless u just want me to take your word for it.. It is calcium hydroxide.. Why does that kill bennies???????!!

Dude....you dump that on your soil grow and your PH of your soil is gonna shoot through the roof. You dont add hydrated lime to raise the ph of your compost tea...thats nonesense...who told you to do this? A cup of hydrated lime in your tea will ruin your plants PH...
Does anyone else agree with me???

Pretty much, yes.
To the OP. Why are you so insistent on using hydrated lime? For ~$5 you could get a 40LB bag of Dolomite or Garden lime that isn't going to toast your plants.
Both the hydrated lime and the *triple phosphate* have been chemically altered and are super fast release and just not suitable for what you are doing.

Don't just take anybodies word for it. You're on the fucking Internet, why don't you satisfy your own curiosity?
Calcium hydroxide is used as a preservative, because it has anti-fungal and general anti-microbial properties. They apparently use it in dentistry also for the same reasons. If you use a bit too much hydrated lime your pH is more liable to go through the roof. Fungus certainly doesn't like it so alkaline and bacteria don't either.

Ok but what i understand about beneficial microbes is that some reproduce regardless of ph.. Is that not true?? The other thing is that it is calctic hydrated lime (agricultural grade). If hydrated lime kills beneficial microbes because it has calcium hydroxide in it, then are you saying that everything that contains calcium hydroxide in it kills the micro herd??!!!??

Seriously, i know hydrated lime can be nasty shit.. I use heavy clay native soil, thats why i like it... What i wanted to do was add more calcium to my compost tea.. Cound i just add gypsum to my tea instead of hydrated lime?? Gypum is like 70% calcium hydroxide and like 20% sulfur or something like that.. But on the contrary calcium hydroxide is still in the ingredients of GYPSUm so can i use that??

Well it certainly wont do the micro-herd any good. Do you want 'some' microbial activity or do you want your soil teaming with microbes?
Bone meal/fish bone meal has calcium. You can put that and/or dolomite lime or pulverized eggshell into the soil to supply your plants with calcium. Gypsum is calcium sulfate (CaSO4), whereas calcium hydroxide is Ca(OH)2. I've never used gypsum in a tea but I suppose you could. Bone meal and fishbone meal are probably more common tea brewing ingredients.

Does anyone have proof it kill microbes ?? Or is this an assumption?? I dont think it wud b recommended so often if it did so much damage. An out of all the people saying to not use it, how many actually have used it. Or are you jus going from what u read in a forum. I used 1tbs per gallon n havent had any problems. If u never used a product u shouldnt comment n confuse people with your own theories.
