Which powerhead and light

[trotsky123]

Hi, looking to buy another powerhead now but don't know which one.
54 Gallon corner tank with FLUVAL 405.
I have a Koralia Nano now which I will put not far from where current of Fluval Ends and on the other side I want to put a powerful one.
There is Koralia Evolution 750, 1050 and 1400 on ebay
Which one would be good enough?
ALSO, have Coralife dual bulbs now - both daylight
When I add T5 (?) light in there and when light goes on on timer for 8 hours, do BOTH of the lights suppose to stay on?
Thank you

On the pumps either 1050 or 1400 will do fine, both are rated for your tank.
As for your lighting question please explain are you talking about the Coralife fixture both lights staying on? Also why do you have both bulbs daylight or do you just have fish only tank?

I just bought this tank - currently have 35 gallon Hex w/ one 50/50 bulb.
New tank has coralife w/ dual bulbs.
The guy who had it before had freshwater ciclids in it and didn't need the T5.
Currently, I have a timer where my light go on at 4pm and stay on till 11pm.
With the new setup, do both daylight and the other need to be on at the same time?

so are you saying you have two fixtures running on this new tank?
"With the new setup, do both daylight and the other need to be on at the same time?"
not until you get corals in the tank and then depends on type of coral you are keeping and how many T5 bulbs your fixture has.

there are dual bulbs in this light fixture
one i need daylight, one i would need marine light

Ok you have power compact one is daylight and the other is actinic. This fixture is on your 54 gal? To figure if you have enough watts for LPS and softies take the total watts of both bulbs and divide by tank volume (54), if you have 4.5 watts per gal or greater than you are good. For SPS you'll need MH; T5's or LED.
