red/brown sand

[Eva1313]

Ok so iv been noticing my sand (white shells) keeps getting red stuff all over it making it look dirty! I did a 10% water change and the next day it was back! What is it and how do i get rid of it.

You should switch your sand to another substrate, or start doing a 20% water change. How big is your tank? Do you have a good filter?

 

[Eva1313]

I have a great filter. Its a uv filtration system. I have a 75 gallon tank and have never had this problem before.

Does it cover in a sheet? sounds like cyano any changes in feeding?

 

[Eva1313]

No it starts in spots then spreads. No feeding changes.

Can you post a pic? And like Ben said up your PWCs to 20% Some of your CUC may have died off and the excess food is not getting eaten. Cyano starts in a low flow area and spreads covering like a blanket

One of my fans for the current burnt out. I wonder if that has anything to do with it.

 

[Eva1313]

I looked it up online. Its cyano bacteria.

If you mean a power head Then yes that could cause it as the detritus is settling and letting the cyano get a foothold
