So I have ordered some 'Bio Balls Biological Filter Media' and 'High Grade Activated Carbon' for the filter, got it recommended the fish shop and it seemed about right, That wont come for a few days and even then I will need it to cycle,
So- if you see the photo, that media I am holding up is from the old fish tank, filled with good bacteria, would it be ok if tomorrow I put it in the trey I am holding above and then add the fish in after, and then when the other bio balls etc come I will add them as well as keeping the old media in? I just need to add my fish to this new tank asap, so would that work or no? (the photo shows the size of it and where id put it etc, obviously id have it lying down in there under the filter wool, just holding it up to show it)
Yes, that will be fine. You don't really need carbon though. Most of us don't use it as it has to be replaced regularly and takes up space that could support more bio media. Carbon doesn't do anything for ammonia/nitrite/nitrate but can be used to remove chemical contaminants such as medication at the end of treatment or staining from bog wood and so on. It can help make the water appear clearer though and some do use it for that. If it's left in, rather than being changed every few weeks, it becomes inactive as a chemical filter, but then acts as a biological medium as bacteria will colonise it.
its now in there, the size of it takes up about half of one tray but in a few days my bio balls should come in the post, ive put some wool on top of it so the water trinkles down onto the wool and then onto the old media, its in the first compartment closest to the back,when the bio balls come ill add them to all the compartments,
ill leave it like half hour and then add my 5 fish into the tank, exciting :)
