I discovered by accident that a foam filter, if left just sitting in your tank, is a great pod safe-haven. Mine is just loaded with pods
. I took it off my Mag7 pump and was too lazy to deal with cleaning it so I just threw in the sump and forgot about it. Pods
are just crawling all through it.
For those with mandarins (like myself) maybe having a block of this foam hidden in the back where you can't see it would be good for maintaining the pod population.
Maybe everyone knew about this already but I've never read anything of the sort.
