Who makes the best PH solutions??

Im using the General Hydroponics PH solutions and having a hard time with rebound. I need to adjust the water 5-6 times to get it to stay down where I want it.
What's everyone else using and how well does it work for you?

Use aquarium products for saltwater. believe it or not the plants in these aquariums are priceless. saltwater aquarium companies don't mess around. the aquarium forums are not exactly like this site. there filled with scientists. and aquarium ph products are meant to stay stable for long periods. try them from petsmart

sorry sound like a petsmart promo. buy it from wherever

i picked up some discuss ph buffer

if used correctly they keep a range of about
5.8-6.4 i think.

it works good, u need to add a tsp every week
to keep it in check

Hell yah discuss buffer. discuss are very fragile and if its safe for them then its prob safe for bud. Its prob very high qaulity. And perfect ph range.
