My reef tank (without chiller and fan!)

[Legent]

Hey guys just wanted to share something...

I've done some research and realised that natural ocean temperatures like the Indo Pacific have ocean temperatures of up to 33- 34 degrees.

I've been to certain marine lfs where their tanks are outdoors and the softies in it are still alive and kicking.

So it got me thinking and i've decided to sell my chiller, off my fan and risk it.

And viola! No problem! My soft and lps corals are doing well and I even keep SPS like birdnests, monti caps and a millepora. A few reefers who got something from me saw that I operate without chiller or fan at all. N ive been doing that for 9 months already

I have no air con installed and the tank temperature stays within 30-31 degrees on a very warm day and 26-27 on a rainy day.

Im guessing its not the temperature that matters (unless its really too hot) but the temperature swing that is of more concern.

What are you guys comments? Anyone tried without fan or chiller before?

My sps not doing well in 28c. Now running chiller at 26c. Can see its better

U serious? My chiller once failed to kick in, temp raise to 33 degree, all my LPS melt, Lineatus and Flame wrasse up lorry, rest of the fishes super stress.

How is your SPS colors like, without chiller or fans?<br /><br />Sent from my GT-I9100 using Tapatalk 2<br /><br /><br />

This is something new. I've chiller down once and can see that gonia not opening.

However, did notice that all the chalice mouths opened. Good or not, need to do a bit of research.

When the temperature is higher, metabolism increases, livestocks need more food. That got me thinking, have you noticed, there are more fat people in colder countries than over here where it is hotter?

[DottyClown]

Interesting. Legent, can post some pics?

[braincoral]

Maybe TS dont know that many coral reef are in

bad stage due to global warming. .increasing temp..

[Kayakkite]

Can I know how big is the tank??

[Legent]

Hi all, my tank is 40 gallon 2.5 ft.

Equipment is just:

1. mazarra razor 160w 10K

2. MP10 wavemaker

3. AC70 HoB filter running carbon n GFO

4. Chaeto in display tank

The rest are just livestocks.

A little background, this tank was not taken care of for about a month. No calcium and bicarbonate dosing. Family issues and tank neglected. Wanted to decomm but recently cant bear with it and redid the rockscape, moved corals around. Some of the corals are starting to show signs of deterioting.

So the white areas are not STN but the side not exposed to lighting at all.

More pics.

Do give me any comments even criticism as I know im not doing anything conventional.

But I have to do disclaimer first what might be ok for me might not be for you! My tank isnt exactly the 'WOW' kind but just to prove that corals can survive higher temperatures. But of course they did that in stages and not immediately.

New acro frag to push the limit

The orange birdnest seems to lighten after being in a low Kh tank for quite a while. Will I be able to get it back to its bright orange color like last time?

Anyway nice clam u have bro

[fatbike]

Wow, tho I'm not into sps, even w softies only, I must say I'm not as bold to try w/o chiller, i remembered telling coolguy last month dat i wanna try w/o both my skimmer n chiller but end up still using it, lol, but really m amazed, many thx for sharing n do update again bro, really interesting

[Sengreef]

me have atleast 5 times chiller problem in my reefing especially happened during i'm oversea and everytime i lost many corals or almost whole tank crashed ... In my experience , 31C for not more than 24hrs is still ok for any coral just stress the corals will not kill them but for few days onward many will die especially most sensitive is not sps but soft finger and leather coral melt away directly ... but in my case , temperature sudden change from 25C to 31C or above ... If slowly raise the temperature take few weeks possible coral can survive for that temperature ...

Legent , your led light and vortech pump will not increase tank temperature but most heat come from return pump too ... make sure your thermometer are accurate enough not giving wrong reading cause wrong info will misleading reefer hor ...

Yeah max temp I see is 31 deg but its during noon only. Not 24hrs.

I can say a few factors enabled me to go without a chiller and fan:

1.My room has no direct sunlight

2. I have ZERO pumps touching the water.

3. The corals are 'conditioned' to this temp slowly from chiller to fan to nothing.

4. I have too much balls (haha)

Interesting bro.. I oso tot its nt possible, but seems ok so far wif u.. kp updating mate..

[Cedric]

I'm running my tank bet 27-29 degrees using just fans without chiller too!

So I agree it is possible to go without chillers.

Interesting... How do u condition new fishes & corals to your tank?

[Legent]

Softies, lps and fishes do well...

For SPS, i'll try to get frags from fellow reefers. But again I dont really do new SPS frags except for montis and other easier SPS's

I see. Thanks for your prompt reply.

I only tried running my lps tank in the balcony with direct sunlight. And compressor producing hot air.never use chiller . But guess what? I used metal halide last time. Temperature was hovering at ard 34-35degress. No problem. Infact the corals bloom even more. Just that have to face diatom problems lol.

[Patrick]

Interesting read. I have often wondered corals in fish farms with no chillers how they managed to thrive... But their water is not warm I think due to high circulation.

[Legent]

Wow now someone beat me to it! 34-35 degrees! Crazy temp!
