Algae spreading like wildfire!

[A320]

Does anyone know what this is? Can't seem to get rid of it......and worst of all, it spreads really quick. Its kinda like seaweed and sticks to rocks. I've had to peel it off the rocks a couple of times, but it seems to just come back.

How do i get it rid of it? Or at least control it?

Thanks

I would highlight your pollution and water temperature as the two main problems. Might want to consider a chiller and also have better filtration/nutrient export. The sump will greatly help so you can connect other equipment to your tank.

This is nuisance algae by the way. Generally most fish won't even eat it.

This is red slime algae. There is a red slime remover that you can try but be careful of the dose. Check the current flow in your tank. Red slime tends to grow when the current flow rate is low. Test your water for PO4 as well.
