What fish shop has the best detrivore kit? I have tried ispf but they had very small portions for the money. How long does it take for a 50 gallon tank that is five inches deep (pure argonite) to establish quality filtration from the sand?
I've heard good accounts of ISPF, Marine Ecosystems, and Inland Aquatics kits, but I think they are all rather small in portion. That's just the nature of detrivore kits. They're intended to seed sandbeds with a small but very reproductive population of detrivores. I recommend that these kits be added after the tank has cycled but before you have introduced any decorative organisms such as fish or corals that might predate on these detrivores. Give it another 4-6 weeks and these species should have gained a decent foothhold in the system. DSBs take a while longer to mature to their "optimum," but it's a worthwhile wait.
