Strange White and Orange Stuff

Bettamay

Hello!

Recently I noticed strange things developing in my twenty gallon fish tank that is not present in my five gallon.
There’s white stuff on the sides of the tank, white dots all over the filter, and orange stuff on the filter cartridge. How do I get rid of this? I use spring water, and this tank is cycled. I took pictures of both tanks side to side for the white stuff on the sides of the tank, the twenty gallon one is on the right. The white dots have a black background, and the orange stuff is on the cartridge.

Looks like hard water calcium stains/deposits to me. Do you have driftwood in your tank? The filter looks pretty normal from that picture.

I do have a piece of driftwood in my tank, would that make the water hard? I'll send another picture of the filter.

No it wouldnt but it will make your filter brownish. Do you know what your pH is?

The first and last pic definitely look like hard water crust. Still looking for the spots. Im guessing some kind of biofilm?

I have all the testers but pH. Also, if its hard water crust, why does my five gallon tank not have it? I use bottled spring water for both.

It could be some kind of slime mold. Still looking... :)

Spring water is generally hard because it comes from the ground and has minerals in it. The only way to tell is to get a GH/KH testing kit to know for sure. It is strange you are not seeing it in both tanks though.
