pH levels

[crow]

This post probably doesn't belong here but I'm not sure where else it belongs , almost needs it own subbie in this section :
Ok just wondering what everyone uses to raise pH . I've used gypsum, calcium carbonate , hydrated lime, calcium sulphate all seen to work but I have read the lime can have a slight carry over flavour that some say is not a particularly bad thing

Its funny you should mention this coz i was wondering myself.
I also just ordered one of these

I have the same unit, seems to work fine. Only used it 3 or 4 times so time will tell.

Oh yeah and I use calcium carbonate, haven't tried anything else

Question what ph do you need and for what product [still learning you see ] how accurate does it need to bee
I have a ph meter i won when i was into aquaponics its a bluelab $350.00 so it will do the job when i find out what you need it for :oops:

Most ppl seem to say between 4 and 5 I could stand corrected ;-)

i've got one of those little yellow pH meters - quite handy - it let me know once when a WPOSW went too acid >3
I tried adding some calc carb but it didn't seem to adjust the pH at all - maybe i was adding too little but i didn't want to add any off flavours so i just left the wash to settle and ran it at SG 1020 anyways

If some of the water comes from reverse osmosis After reverse osmosis the water contains no minerals and is very soft. The water is remineralised by adding lime and carbon dioxide,
Water with no minerals can damage pipes and if water was acidic could also cause problems.
