how long does it take your chiller to cool your tank 3 degrees? 90g-200g tanks

Mine stays on for maybe 15min (+-5min)at a time, temp set to 80 on a 180g. JBJ 1/2 HP

[sammoorefield]

whoa! thats pretty fast.....1/2 hp tho

[chalowolf]

Sandman how often does it kick in durring, say an hour?

[sandman450f]

Say yesterday, fairly warm probably switched on 4 maybe 5 times, from say noon to 6pm. So under once per hour. Everytime it came on the house ac came on just afterwards. Tons of heat transfer by that jbj.

I'll add to this, before I used a jbj 1/10 on a 60g, which worked alright, I never really new when it came on because it was quiet, however I am sure it was no where near as efficient (as far as time running) . I later used the 1/10 on my 100g with plenty of fans in the hood. It worked but terribly innefiecient was probably on for say an hour at a time, and during the hottest portions of the day was on continuously.

I then used the 1/10 temp on my 180 for a few days before i got the 1/2 and even on the cooler days it came on say around 11am-noon and stayed on until 7pm or so

I havent even installed fans in my canopy yet for this 180 (waiting until I redo the lights in the next day or two) running 3x400w Mh, but I do leave the canopy lid up 24/7. I am impressed with it's performance, though I never bothered to calculate electric consumption.

Also, I will point out that just a degree or two of difference on where you maintain your temp can cut chiller activity down substantially. I used a bad floating thermo that was off by at least 2 deg and calibrated my 1/2 from that, ended up being I think 4 deg dif from how the 1/2 was shipped, and 2 deg dif from my prev calibrated 1/10. After I got a couple dif digital thermos, I found that I was actually keeping my tank at 77 as opposed to 79 where I wanted it. The chiller ran much more frequently then (on cooler days) that it does now on hotter days.

i have a 120g with a 25g sump after displacement about 110g total volume. I have a 1/3 hp Current USA chiller rated for 300g it will drop the temp in 13 min flat from 80 to 77

It was over 90° here yesterday and the chiller never came on. Usual cycle time for the 1/4 horse on the 300g is about an hour. Swapping it out thursday for a 1HP to get me through the summer. The system does have 4 large 110v fans that do most of the cooling.

When this same chiller was on a 110g at home it had a cycle time of about 20 minutes, 2-3 times late afternoon and early evening. That room was always hot because of the lights and chiller.

alright, lets see here, my chiller just switched on 81.1 deg at 10:58 (earlier than I thought it normally does). Ambient temp pretty cool, reading 70 inside right now. Lights came on at 10am

[sandman450f]

Dang, never seems to work out the way you recall it does, now 11:14 temp reading 80.2

And gotta run out to Hacienda Heights now so not gonna be able to finish this experiment, well now reading 79.8 @ 11:19 oh well

It takes my 1/5 hp about 1 hr to drop my 120g sps tank 3 degrees. I prob need a upgrade.

[Frankysreef]

mine runs about 1-2 hours when it kicks on.. 1/4 hp on a 225 + 60 gals including sump and fuge.

[Fuzzy Yarbles]

Takes me about 15 min for my 1/5 hp chiller to cool my 60gal
