Alternative to Hydroguard

[Gjohnstone]

I was wondering if anyone had any suggestions of alternatives to Hydroguard? That is beyond H2O2. Using it to keep the root zone healthy in my DWC. Thanks!

I don't know if you are in the US, but I've used a product by Southern Ag called Garden Friendly Fungicide. Same bacillus as Hydroguard but much more concentrated. There are threads on it. I haven't run any type of chiller on my hydro systems for the past 3 years without any issues running this product.

I've been using Great White mycorrhizae for a while, and I like it much better than Hydroguard because in the long run, I've found it to be cheapter. Hydroguard expires 6 months after you open it, but GW stays viable for much longer: shelf life is 3 years.

Thanks everyone! The Southern AG product what ratio do you mix it at per gallon?

Howdy Gjohnstone, I use the GH Florashield (at the rate of 2ml per gallon) in the reservoirs to help control algae growth and in a stronger concentration (as per label directions) to clean up the equipment (water pumps and tools). This, with blocking light leaks, has helped keep the algae and mold growth under control for me.
