I've got a new better filter coming tomorrow and putting my media sponges in it so I'll keep a eye on them I don't really want to use medication with copper as I really don't want to kill my assisian snails and getting them out would be easy and I haven't got another tank ,I've got vacuum tube for the gravel,thanks for your advice its much appreciated Peter
I'm getting the Fluval U3 filter today to upgrade on my two stingray 15 and 5 filters which are running at the moment,should I try to transfer the sponges to new filter as not sure they will fit in the fluval U3 cartridges or could I run one of the stingray filters with the new filter if yes how long would I need to do this and what stingray filter should I run with new filter the stingray 5 would be preferred for space but obviously smaller than the stingray 15 which has more media
Can I put my stingray sponges in with the bio media and take out after a month and float a little sponge from my smaller stingray filter in the tank take out after 2 weeks and run the new filter like that ?
That won't work. The beneficial bacteria live in the media, and you only grow as much as the waste from the tank can support. That means the Stingrays will carry on doing the work and very little bacteria will form in the new filter because you already have enough in the Stingrays. Put all the Stinray media in the new filter and that way you transfer all the bacteria.
I filled one cartridge in the new filter with my stingray sponges and cut some little bits in with the bio media I'm also running my stingray 15 for a month until the new filter gains some media is that ok ?
Remove the Stingray 15. If it's in there its presence will actually prevent the new filter from gaining more bacteria because there will already be enough with the Stingray running. If you leave it, you'll get a spike when you do actually remove it as the new filter will then have to catch up to the number of bacteria removed with the Stingray. So you may as well do it now as later.
