Hi,a few days ago i realized my tetra ph test was marine not freshwater,i got the test online,dont know if they sent wrong one or if i choose it,anyway ive been testing with that for 6 months or so,my real ph is 8,i thought 7.7 was high when i had wrong test,so 8 is like hell,ive added peat in the filters, does anyone keep clown loach in this ph range!,id like to bring down ph to 7,
