Although I would like for simple H2O2 to work for me, unlike Red, I have not been successful with it in F&D. Maybe it wasn't strong enough of a concentration in the water or I didn't refresh it often enough. I've tried two types of bennies, both of which work, but one I am going back to because I have a place to store it.
- "Brewed" Bennie Tea (Hydroguard, Great White, Molasses, brewed with air stones for 36+ hours)
- tried in UC RDWC
- Pros: Clean if initially decanted from brewer to bottle without froth. Doesn't froth up even with 7 air stones and a constant 300+ GPH under current.
- Cons: Almost 2 days to brew, then needs to be refrigerated or used within a couple of days. Better to make bigger batches and refrigerate vs. having to make a little and use up right away, especially if you have more water to treat).
- "Instant" Bennie Tea (Hydroguard, Great White, Recharge) (credits to
@Phylex)
- tried in F&D Tote and RDWC Tote
- Pros: Easy. Add ingredients in jug with water and shake like crazy. Eyeball amounts. Recharge is a powder so it can keep for longer. On the fly batches are possible. No need for premaking and refrigeration.
- Cons: Can be frothy, especially if eyeballed amounts are a bit too much. If used in UC RDWC, the frothiness could bubble up out of the net pot if the water was high enough. Stains. The brewed tea can stain when made with higher concentrations but typically the brewing reduces this quite a bit. It doesn't seem to harm anything, but can be messy.
This next run I'll have aquarium UV in my RO collection cans to use for whatever (even outside of watering plants, just in case), then add brewed bennies to the feed water reservoirs.
