HI There, Im new to the site and have a question. I just bought some fish stuff and after i mixed it it has a ph of 4.7, am I supposed to raise it back up to the 6.7 im supposed to have? If so what can I use to bring it up? I have ph up but I put like 20 drops in and it didnt go up much at all. any household products? grow store is to far away. any help would be great, thanks
