How to get rid of these red stuff?

[Shifty203]

How long has the tank been setup?

Run gfo to lower your phosphates

Also, what type of sand did you use in your tank? It may be difficult to siphon properly if it is not a coarse grain.

I took over the tank , I have it for 6 month but it's running with same sand and live rock for over 4 years, and they just showed up

You are right it is not easy as the sand is really fine

You can pick it out by hand as best as you can. Are there any powerheads in your setup? Once you manually remove it, you can move a powerhead closer to the area to increase the flow in that part of the tank.

Worst case scenario is to use Chemiclean but that is only a temporary fix. It will come back if the root of the problem isn't fixed, and when it does, it gets harder and harder to remove.

And make sure you are using RODI water so that you are not adding any excess nutrients into the tank.

Thanks for the help, currently I remove them with hand
Could I get something to eat them?

Try to siphon out what you can and do a few water changes. It should help out tremendously.

I don't know of anything that eats it.
