Old thread how well did hydrorush work? I got a 1 quart bottle with a titan flo and gro I purchased a while back. I grow coco now, threw 40 ml in my 50 gal rez. Hoping it keeps my ro water clean and o2 happy. Raised my ro water 80 ppm, 110 ppm total. started feeding my seedlings with hydrorush/ro as of today, curious as what the benifits may be.
