yet another Matrix question...(I posted a different one on another forum).
I have this tub of Matrix I bought on Black Friday. I freely admit I'm a sucker for sales, even if I don't really know what I'm buying - lol! For the record, it was 60% off & free shipping - just sayin' in my defense
I wanted it for adding surface area for biological filtration, but honestly, I don't know how to use it. I plan on putting it behind my Hamburg Mattenfilters in my tanks. It will be out of sight and in the filtration flow. I will be setting up two new tanks in early spring so I'm going to put some extra Matrix in established tanks now, and harvest/use the colonized media to help jump start the new tanks when they are ready.
However, one of my tanks is a 40B with only a sponge filter attached to a powerhead. Since there is no filter to add the Matrix to, will it still do the biological job if in bags/pantyhose within the tank next to the sponge/powerhead? That way it's in the flow path. I'm thinking I may just put an extra HOB I have on the tank, but this is in my bedroom and the HOB is audible - whereas the powerhead is silent. This was supposed to be a grow out tank for some fry but they are still in there and getting to the 1" size because the new tanks aren't ready. (about 45 Columbian tetra fry) I know it's overstocked, so I do 15% to 20% water changes every other day and the water is good. The tank might as well be plantless - three small amazon swords, a clump of windelov java fern the size of a softball, and a racquetball size clump of java moss. I'm going to tear this tank down in within two months so I don't want to plant it. It isn't bare bottom, it has CaribSea FloraMax so there are footholds for nitrifying bacteria now yet I still want to add the Matrix. Since I ramble, the question is can I hang bags of Matrix next to the powerhead and still reap it's benefits?
Question #2 is on how to use Matrix; once it's in my tanks and colonized with beneficial bacteria, what then? Do you leave it in the tanks indefinitely, or do I have to take it out & rinse it occasionally like a sponge? The tub doesn't say and I haven't found any info online to tell me. Oh, and am I supposed to rinse it first? It's rather dusty.
Yeah, this was a long wordy post - I'm never coherent before my caffeine kicks in, but I appreciate any info!
