Filtration and powerheads

[Crazycraven]

I have a 125 gallon saltwater tank with probably 75 pounds of base and live rock , a fire fish four little crabs and a clownfish . I want to go reef with fish . I have three 404 fuvals and two 402 powerheads . Are the powerheads too much ? I know you need as much flow as u can get and oxygen is always a plus but it just seems like a lot of tiny bubbles . It kinda makes the water look not as clear . They are at seperate ends of tank too .

You shouldn't get bubbles from your power heads, try adjusting the direction so it creates a slight ripple at the top without directly conflicting with the current from another

Ok so then how do i airate the tank ? I put a tube threw the hole in the nozzle to creat current and airate

aeration happens at the surface. you don't want any air lines in the display. just make sure the surface is turbulent. aim a power head upwards towards the surface and you will be fine.
a protein skimmer also adds air to the water.
