I mixed the salt yesterday (pour salt into RODI water in the tank). Today the water is quite cloudy (you might not see in the pic but it's cloudier than normal). And there's some white stuff on the water surface and around the powerhead. Is this common? I only have 2 powerhead placed in the middle. No surface agitation. Salt is Instant Ocean.
