ph up/ph down

[Cranky]

is it true that you cant use ph up and down in the same bubblers????i dont mean mixing them together consentrated..i mean welll,

say i was at 6.3 and added ph down but i went to far say to 5.3....could i then add ph up to the bubblers to bring it back up to say 5.8?

ta very muchio

cranky:cool:

i dont know if you should, but i have with no ill effects.dont know if id do it on a regular base,but this one time prolly wont hurt anything.

Not so sure it isn't allowed but do agree with midwestbluntman, don't think it is a good thing to make a practice of. I did something similar a while ago, added too much ph down on a fresh solution to my tank (ebb and flow). Instead I waited until the next day to see where it would drift. Probaby made no real difference to wait out that day but just thought I would let it stabilize and then check it again. I natural ebb and flow washing thru the system raised the ph overnight and I didn't have to correct it so quite so much. I saw no adverse long term effect.

In bubblers it might be easier to just start over, but i really hated doing it that time as I had just filled a large tank.

i guess ya shouldnt bro.

the quick shift in ph level and reaction causes polarisation.

tap water is a good ph up idf u were heavy handed
saves making the mix up
wat is the bad things with this ph up ph down mixing combo??
never seen any ill effects

When you mix certain chemicals together you get precipitation and slurry which will clog pumps and nozzle's and filters and lock up some of the neutes in the solution better to just dilute with water until pH is right and the next day adjust the ppm:2cents:

yup, you'll end up with chems percipitating out of the solution as the acid and base react. Try raising it slowly, using small amounts of ph adjuster.

I second that quote :share:

Also Liquid Silicon, or any product containing potassium silicate (sp*) This is a very good way to raise your pH and add valuable elements to your plants ;)

EDIT; Hey Cranky, just got back from your neck of the woods, very beautifull I must say :D

ya should of called in for a cup of tea bro;)

next time aye:)

Hey Bro,

I would've gladly popped in for a cuppa, in fact I was planning to meet up with a couple of people while we was over that way but the dragon wouldn't let me. :o She quite clearly pointed out out to me that this was our first holiday in 15 years ALONE, and that under NO circumstances was I going to have a session with anyone if I wanted any of, you know what ;) :rolleyes:

We will be comming back that way for sure, so another time eh :D

but the dragon wouldn't let me.

ROFL!!

Well, strictly speaking, pH up is adding base, or the hydroxide ion (OH-), while
pH down is adding acid, or hydrogen ion (H+). If your solutions are meant
strictly for pH adjustment, then little or no precipitate should develop (aside from water).
HOWEVER, as everybody knows who played with vinegar and baking soda, this
can be a rather violent reaction if permitted to occur quickly, generating a
good deal of heat.
Now, I'm a soil guy, so all my experience in pH adjustment comes from high
school chemistry class, but if I were to attempt to adjust pH with neutralizing
solutions, I would do it VERY SLOWLY!!

Never mix pH up and pH down in the same res, this is not good for the plants and the adjusters will take up alot of room for nutrients.

Here u can see basic what happens with the pH, why it moves up and down. When u understand this and know how to use it, you can adjust your pH and keep it in balance by keeping your nutrient mix right by adding the right nutrients. This way your pH will natural move up and u adjust it down, few days later it will have raised a bit but all u need it then to add water and nutrients and the pH should settle in as wanted ot u will need to lower it a bit with H2Po4 (phospheric acid)

When your pH then start moveing the wrong way, it's indication of a buildup from leftover salts and you should change the res 100% and make a new nutrient mix for your plants. I change res every 3-4 weeks, it saves alot of money in nutrients and all it takes is a big res.

I recomand ppl to have atleast 100 liters res for a small setup, I run 150 L mysef for a small Aeroflo28 and thats to small IMO

This should be helpfull for all growers
