Acidify soil?

Has anyone got any tricks for acidifying soil?

Usually I wouldn't bother with pH, but I used some soil in a few 10g tanks that I want to breed apistos in but it turns out the soil is pH 8.2 which is a bit too high for these fish.

I am unsure how much peat will acidify the soil. I almost wonder if I could inject sulfuric acid into the substrate to neutralize all the alkalinity?

Hi Zapins,

Actually I would try using peat; here is an article that may help you get started.

I would suggest Eheim Torf Peat Pellets available on Amazon or Big Al's Pet Supply.

Do some water changes. without fertilizing. The soil probably has a lot of potassium or sodium in it. A few water changes should bring that down.

With apisto's, I would not be too worried bout how much peat to use, but might would have wanted it mixed into the soil beforehand.
Not to say placing some in the filter, or cutting source water with R/O will not bring desired result's , but might take some experimenting with to get right %. (in a bucket,tub)
If tank was not too large,,I might consider re-do with pure sphagnum peat mixed with soil.
Seem's is what I must do to keep some of the soft water species due to fairly hard water.
