Aragonite used

Can I ask how long does it take to raise the ph?

I think I made a major mistake here, using aragonite which I bought in a haste yesterday and mixed it with plants substrate (actually I thought it was white gravel). On the package it said marine and freshwater suitable, aids plants...bla...
Later in the receipt I saw it said "Aragonite" and I was like someone had just shot me. I know that I must remove it but all stores are closed today. Any idea should I remove it now or do I have time?

It doesn't change it a whole lot enough to worry. What is your tap PH? And what are you intending to keep fish wise ?

It's a stable slow way to raise PH .. I can't recall exactly how fast it raises or how much but having put aragonite sand in one of my tanks about 1.5yrs ago .. I found it didn't raise it enough to where I needed. After about 1month I gave up and added marine sand,marine salt, Epsom salt and aquarium salt along with limestone to get hard water. If I had to do ALL that to get a high KH and PH to 8.2 from PH of 7.2 then I think you don't need to worry

oh thanks! Your post was such a relief. The water ph here is 7.5 therefore I was worried that it might shoot it above 8.5 or something. For now the aquarium host 6 guppies and 7 cories. thanks for the reply.

It might go up to 8.. But still I wouldn't worry .. Especially with those fish. They are pretty adaptable to different water chemistry and are not generally soft water fish. More stress can come from fish being below the water hardness they need then above it.

Yes, I keep tetras and cories in a tank with crushed coral sand (originally an african cichlid tank) and they are very active and healthy. If you want to naturally and effectively lower ph, then addd a considerable amount of driftwood. Thats what I've always done.
