Anyone running 250 halides ...

BASSCYN · 08-19-2009, 4:23 PM

With OUT a chiller?

I am getting closer and closer to breathing some life into this beast. This may be yet another roadblock.

175 tank
total water volume will be around 220-230
4x250 halides

Set up is in basement where it is a little cooler. I was hopeing to get away with a few fans.

Any thoughts?

Thanks!

I dont have a chiller... 2x250 with bulbs about 4-5" off the water.. Granted it runs on the warm side in the summer 80-81..

on my 75 with a 20 gallon sump i am running 2x250 mh with no chiller and it is staying around 77-78 with the bulbs 10 inches off the water

i am runnning 1x250 on a 45 gallon with just a fan and stay under 80.

Same here. 2 x 250w. No chiller just a ceiling fan.

bexi20 · 08-19-2009, 4:30 PM

I run two 250w with four 54w T5

I do not have chiller, just a fan. You have seen my basement tank. I am running 3-250's about 9" above the water. Using only a fan to cool timed to come on after MH.

2x 250 MH, no fan, no chiller, 6" deep frag tank, have to heat it to 78-79. Wierd, I know, but it is what it is!

Considering that they are about 30" off the tank.. thats no real surprise...lol

I probably should lower them a little bit on the right side....

2 x 400w on a 150 gallon and 55 gallon sump (sump in basement).

When I had the lights hanging and no canopy (open top) I only had to run one fan in the summer and no fans in the winter.

I now have the lights enclosed inside a canopy. I have had to add a few more fans.

2 x 250 on a 90G, 8" off water. With one fan linked into a controller, we swing from 79.0 to 79.5 during the summer. Also have three mag drive pumps in the sump and two 70 watt halides on nano in system.

theplantman · 08-19-2009, 5:46 PM

run a single 250 over my 34gal cube. 8" off the water with a single 3" fan blowing across surface. Low temp 77.8 high 79.1 in middle of summer with room temp at 76.

I have a 125 with 40 gallon sump 20 gallon ref. and a 20 gallon frag all run together with 3 250w halides and no chiller and it stays 79

BASSCYN · 08-19-2009, 8:02 PM

Whew!
Thanks guys I feel much better.

Let there be light!

Mine (2x250 on a 90) will stay under "the mark" (82) without one, but the chiller runs probably 10min every 2 hrs to keep it at 80, this with an ambient temp of 78.

Amici · 08-19-2009, 9:25 PM

I have a chiller with 2x250w on my 90 but never seen it run. I have two window fans in the back of the canopy blowing in and the top has slates that hot air flows out of. I even am going to tie in my 60g cube into it so I will have roughly 180g of volume.

bobz · 08-19-2009, 10:36 PM

I'm running three 250W MH and two 54W VHO on my 210. I have not had to use a chiller but I have about 450 gallons moving through the system

molson · 08-19-2009, 11:10 PM

Running 3x250's, one on the frag tank and 2 on the display with no fans or chiller, temp never tops 79.2 but being from north of the Mason-Dixon line my house is at 70 degrees constantly.

Keep me updated on that aquamedic light. About to run the 3x250 2x150 myself
