Compost tea

I've never had one look that frothy, the plants should love it. The only time I get froth is when using carbs, like molasses. Now a days, my tea is more slow brewing without carbs. I don't get any froth. I found that if I don't add carbs, add some sort of bio filter in the bucket and allow it to cycle like an aquaponics tank, one brew can feed many plants over a long period. My last brew was 12 months old. It fed many hydro vegetable plants from seedling to fruit, only using the tea, nothing else.
