Water changing colour

[Sawda15]

I’ve got a Cichlid tank and since I’ve changed the pump and filter; got a new one; the water has been turning a reddish colour.

Any advice to remedy that ?

Thanks

For starters, what’s the brand and model of this pump? Is it new or used? Also, is your tank new or has it been running for some time?
