Need Advice On Koralia Powerheads

so here's how i set it up

 

You do however get what you pay for. If I had it to do over again, I would use a pair of them on my 75. My next tank will use Vortechs.

 

i'll check that one out too

 

yea i deffienentley would not want to spend 300 on a powerhead, that's a whole $50 more than my skimmer, and i still need to save for my light

 

You need to remove those black tubes completely. That is what is causing the bubbles.
Maybe she doesn't need new powerheads at all

 

only worry, does 3 of them take up a lot of space? and i'm also worried about running out of room for plugs, my current extension cord is full, and i have another one already full from my puffers tank, and i think my light alone is going to have 2 plugs, lol i don't know how i'm going to be able to plug everything in without blowing out something

 

don't we need the black tubes to adjust the flow? i tried playing around with the air valve, and as soon as i took the air valve off just to see, boy did all hell breake loose with the bubbles

 

Make sure the powerhead is submerged completely. You do not need any air valves or hoses on them.

 

yea their fully submerged, i'll take them off right now and see. And if that's all i need to do then i guess packleader is right and i don't need new powerheads after all

 

No. The tubes do not adjust flow. They adjust the amount of air being mixed into the flow.
Remove the tubes and they will suck water instead of air
If you want, throw the tubes under water. See if the bubbles stop after a little bit
