In a refugium you don't want or need any rock or shrimp crabs or anything just some deep sand and algae .. It requires no cleaning and messing with other then every so often go in pull out a few had fulls of the algea and toss it into a bucket of fresh hot water to kill it.
All you want the refugium/refuge for is a safe place for the plants to uptake the DOC's and the Pods and sand fauna can live and grow naturally with out fear or any predation by larger animals that would feed upon them in a main tank..
Don't per-filter the water reverse light it just 10 Hrs aday 12 hrs max and let it be.. There are so many here lately who think these are some new magic idea that they are just overly thinking them .. And trying to improve on a totally natural method of filtration. And slow slow slow flows .. _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
