Aquagrit changes the Ph.
Andy

Really? I don't recall seeing that on the bucket. Upwards or downwards?.

There is Aquagrit (green bag) that changes the Ph downward and then there is Underworld Aquagrit (Orange bag) which doesn't. they are 2 different manufacturers.

I got mine in a large white bucket, around £15. I'll have to see if I still have it. Thanks.

The most common one on the internet is the green one which does alter the Ph. MA sell the underworld version. Pricewise the green one is half the price.

My water is extremely soft (KH=0) and my pH is about 7.5 or so. To me this seems a difficult combination to think about. If the pH were more acid it seems like I might have a great situation for plants and various tetras.

Not sure on the KH issue here. That is something Dave or Wolfen will have to answer. 7.5 would be fine for both Tetras and plants depending on the KH issue. Latest theories are that plants actually do better in moderately hard water!!!

Moderately hard water.. well, that could mean it might make sense for me to consider maintaining a handful of crushed coral in my filter after all - had been weighing the pros and cons of bringing that kh up as a general thing, but thinking that a lot of plants really liked acid water was part of what held me back.
