Normally it takes me around 10 weeks to cycle and fully mature a new shrimp tank, but when I visited Shrimps Affair in Singapore, Darick told me his soil can be ready in 5–7 days. So I brought it back to the UK and tested this “7-day cycle” method by setting up two new shrimp tanks using an acrylic UGF box, Shrimps Affair soil (two-pack method), RO water, and my usual bacterial powder that I’ve used for years. After one week I did a massive water change (around 90%) and added shrimp very slowly—about 10 at first, then more each week. The tanks grew biofilm and green walls fast, and the shrimp were straight away grazing, which is exactly what I want for baby survival. I did notice ammonia was still present for quite a while (zero nitrite and zero nitrate at first), but with the low pH (around 5.4–5.5) the ammonia is less toxic, and the shrimp stayed active. I did make mistakes though: I overstocked the Yellow Galaxy tank and even got green water/bacterial bloom, so I had to use a UV filter and be more careful. By week five the parameters finally normalized and ammonia went away, and by week eight both tanks were stable and even breeding. Would I use this method again? Yes—but I’d be extra careful with stocking, feeding, and I wouldn’t start with super sensitive, expensive shrimp.
