Hi,

I was wondering, I do the EI dosing with the weekly waterchanges (50%) and after the waterchange the PH goes from 6.6 to 7.1 a 7.2 according to my probe(Tapwater is 7.6) KH is 4degrees. (According to the testkit )

I did the EI dosing and waterchanges without fish, but will this PH swing not harm the fish if I put them in next week? Stock will be mainly tetra's and some loaches and Cories. Tank is 75 US Gallon.

If so, what is the best route to go? Lesser but more frequent waterchanges? Or must I prepare the tapwater to a more matching PH? If so, how?

Thanks in advance
