Knowing more about corals

[CookieCrunch]

Hey reefers !

May I ask a dumb question, is there any corals that can be kept without a chiller ? Currently a fowlr tank running a fan .

Temperature average 29-30degree .

Thanks !

Maybe some soft corals? Zoas, Xenias, mushrooms etc

If urs is a smaller tank, can try to freeze distilled water and put those ice cubes in the tank in the morning. can help to keep the temperature low and also "top up" ur tank water

Mine is a 2ft cube . morning too rushing for me, I have to leave house at 6am ! Haha .

2ft cube abit too big to do that.

Try to make sure that as little as possible sunlight reaches ur tank throughout the day. And when out of the house, try to allow for air in the house to be circulated (maybe have a standing fan running). It usually saves 1/2 to 1 degree for u.

I think the worry is that when the hotter months come by, room temperatures can spike to 32-33 degrees and with pumps and lights running, our tanks are usually 1-2 degrees warmer then room temperature. That is a real problem for our corals.

You may want to use those aquarium fan to cool your tank down.

Think 3 to 4 of it is enough

Yup .. these can be kept without a chiller .. but after a while u will wan more like lps and sps corals .. why not just invest on a chiller?

I used to keep bubble, sun coral, leather, etc in a 4ft tank without chiller (see pict below). I used two fans to bring down the temp. what would help further is to have strong flow at the water surface to dissipate the heat.

What critical to the well being of the coral is not the absolute temp but rather the fluctuation of the temp.

[CookieCrunch]

Yes I will invest in a chiller next time ! But now don't have the capability yet ! Need to save for it . Haha . Still a student .

Alright thanks for the advice guys ! Yes I'm also running a fan hence the temperature is about 29-30 .

keep an eye out on pasar malam too. Might have a couple of good deals lying around.
