Fed the girls 3/4tsp Pro-Tekt and 3/4tsp Foilage Pro with ph set to 5.9. They have got two feedings with tap water and they are still thriving. I believe they are gonna be ok with the tap water so that will be great for me. It will save me time and energy packing 5-gallon buckets at a time from the spring out back. I will get a few pics up tonight or tomorrow.
