Hey guys! Tony from nova Scotia Canada! Love the show! And never miss an episode. My situation.. I grow in living soil with blumats for watering. I have a 5 gallon res with a couple of air stones and a small aquarium pump for circulation. I’ve read about the benefits of a little bit of hydrogen peroxide in the reservoir for synthetic growers. But I’m worried it will kill my beneficials. My reservoir is only RO water, pH adjusted to 6.2 and that’s it. Any tips on preventing or managing biofilm in your res?
