Powerhead ?

[saltyj]

What are the powerheads that attach outside of the tank and have the magnet so the "fan" is inside called. And what is a good/cheap one for my 120?

 

[Trueno22]

they are the vortech MP40W they run about $419 new and around $360 and under used.

 

[ben&bobbi]

the vortechs? i don't think they have a cheap one!

You could try the Koralia pump. It has a magnet to hold it to the tank and uses a prop for flow....they are not too expensive.

 

[saltyj]

Koralia it is. Who the heck spends $400 on a powerhead holy crap!!!

 

[saltyj]

ok now what size 1,2,3,4 for my 120 I want to get a minimum of 2 one from each side and maybe 3 one from the back.

 

[Trueno22]

then i would go with 2 koralia 8's

 

[Trueno22]

i meant 5's

 

[saltyj]

Ouch the 8's are still expensive. Am I wasting $ if I get 2 or 3 of the 4's??

 

[Megabite]

So you have a 4' or 5' 120?

 

[saltyj]

ok still might stick to the 4's so the wifey doesn't have a heart attack

 

[saltyj]

Megabite I have a 48" tank if that's what your asking

I use 2 k-4's in my 90g. If your 120 is a 4ft tank it will be plenty. If it's a 6ft tank i would get 3 of them. The k-4's move quite a bit of water.

 

[saltyj]

Thanks Dugg do you find it helps at all with hair algae. I'm get some growth on my LR. I am in the process of getting new bulbs and just replaced all the filters in my RO, but I'm hoping better flow will help too!

 

[Trueno22]

If you want I can let you borrow my sea hare. He will it eat it all up good as gone.

+1, that's why I was asking. Depending on how your rock work is set up, you may need to get a third smaller PW to sweep a dead area.

I don't get algae in my tank, but i do water changes EVERY week. I do have a ton of flow in my tank, but i don't have algae issues in my other tank either and it has no powerheads at all, so i really can't say the flow in my main tank is what keep it algae free. I think it's more about keeping up with water changes and growing lots of cheato in the sump under 24/7 lighting. I change 15% per week with 0 TDS water.

+1 once again

I don't have a fuge but I am over skimming. Keeping up with everything and putting in the time is the "secret" to success.

trueno I would love to borrow your sea hare, but I have an aggressive (huma huma, lions, puffer) will he get eaten??

 

[Trueno22]
