Brown / Rust orange color on some of my Matrix.

[CommonCurt]

Is this okay to use? Looks like brown or rust orange color on about 20% of the Matrix I just ordered from Amazon.
I tried scrubbing it with a toothbrush, but it does not come off.

Aloha,

I’m going to add a new HOB filter (AquaClear 70) to my 55 gallon community tank but I’m going to replace the ceramic noodles and activated carbon it comes with with a small Purigen bag and Matrix (I will keep the sponge).

How long will it take for this filter’s...

Hi, hoping for some help and didn't see this combination of issue in your questions. I've bee using various products to lower Nitrates and just realized I think all of them also remove tannins, which I have been adding to lower the pH. Do you have any products that do that? Or recommendations?

Hello,

I was wondering if Seachem can clarify a few things about Matrix. I have been investigating and some believe that Seachem Matrix is just cleaned sterilized Pumice. Is this true? If so do you add something to it so it denitrifies Ammonia, Nitrite, and Nitrate? I would rather...

I was planning on using the seachem pond matrix as media in my wet/dry sump. Will this work well? as I have heard that matrix works better if its completely submerged in water.

Hello, and thank you all in advance for your help!

I have a little betta "waterfall" tank. It has a tiny pump which I only turn on occasionally (because the bettas are not fans of the flow) and a white "filter" bag filled with pockets of carbon. Here is a link to the...

Just getting my tank started and wanted to see if ayone had advice for me.

Hi,

I have Seachem Matrix in my canister filter and Seachem denitrate in my internal filter (low flow).

During one occasion when my fishes are sick, I added medication in the form of Potassium Permanganate causing the seachem matrix to turn purple. After repeated washing,...

I am curious if there is any silica/silicates in Matrix or De*Nitrate, more importantly if these products could possibly leach silicates into the water.

I am having brown algae problems with low nitrates (10-20); phosphorous/silicate removing medias don't seem to help much either. ...

Hello, I'm using Matrix as the bio-media in my freshwater tank and I happen to have some extra since my filter is an HOB. Can I put the extra Matrix in/on the substrate in my tank? If so, will it do any good in terms of increasing the biological filtering capacity or does Matrix really need to be in...

I was thinking last night,,,what would happen if one placed a layer / bed of Matrix under the subtrate of a tank. Assume 2 inches of Matrix with about 2 or so inches of gravel on top of it.

Would this allow the Matrix to be in an oxegen deprived environment so as to allow the growth...
