I've been cycling my water for about 3 weeks now. The water last week was starting to get an orange tinge (Alge like). The leaves on the pepper plants were starting to go slightly yellow so I was told to use the MaxiCrop Liquid Seaweed with Iron in it. I put well under the amount that it was recommending but the water is now a brown/green color. Is that normal due to the seaweed? I did test the water over the weekend and it was all OK but the Ammonia was slightly high .5 to 1 ppm. I need to add some more goldfish into there I think I'm down to a dozen in the pool ~300 gallons only 3/4 full.
