The ambient temperature is 72F at the moment (quite low for the time of
year). The Nano is up to 88F. The new tank is 80F before I switched on
the AC. There is no AC in the room where the nano is.
My thinking is that if I move the corals out into the big tank then I
can keep the nano as a FOWLR and reduce the lighting accordingly. The
fish do not appear to be showing any signs of distress - just the corals.

That's too hot. I think 85-86 would be the extreme upper end. They can
handle 90, but any short power failure would suffocate them.
Can you position the nano close to the big tank and have them use the
same sump?
There are also reasonable chillers for nanos:

Managed to get it down to 86F by turning off one of the lights and
leaving part of the top open. I'm not happy with the level of lighting
for the corals (2 T8 tubes giving just 30Watts - tank is 15 gall) so I
think I'm going to start moving the corals. Unfortunately I can't move
the nano. Stock is some mushroom rock, button polyps (v. unhappy), some
star polyps, a capnella and a frilly mushroom colony. One of my urchins
appears to have gone awol but could be round the back of the rock.
Took a look at the chiller - looks good but sadly hasn't made it across
here yet. I will certainly look around to see if I can find anything
similar for future use.
Thanks

That should be easy enough to work out. Most power supplies I buy these
days will take either 120/220.
If you want a controller, it looks like you need this:

Contact me off list and I'll ship if across the pond for you. Given how
low the dollar has gotten, it should cost you about a quid.

Thanks for the offer....generally ordering from the US isn't a problem
for kit apart from the power issue but hubby is sharp on that sort of
thing. I'll see what is available locally first though.
Temp is now down to 84F. I've moved the capnella and one of the star
polyp colonies over to the other tank. The capnella is looking a bit
better but still bent in the middle but I'm sure it will recover. The
stars aren't out yet so I'll give them a bit more time. I couldn't get
the other star colony out of the tank as the female clownfish decided it
needed to be protected and kept biting me whenever I went near it. The
mushrooms and xenia seem fine for now. I've located the other urchin and
it seems OK. I'll stick to just the two tubes again tomorrow and see how
things go.

A friend of mine who needed a chiller, he used a mini refrigerator. He
drilled 2 holes in the side of the refrigerator, He used filter tubing,
rapping it around the freezer coil several times before the water returned
to his tank. If he needed the water colder, he would add more tubing around
the freezer coil. It was a hit or miss process until he got the proper
length for what he needed.
What I can not remember is if the tubing, on one end was hooked to his
filtration system or if he used some sort of power head to move the water.

I have a mated pair of tomato clowns now. I'm surprised by the size of
the female. I bet she'll bite as well. I'll need to be a little more
careful around them.

My female only tends to bite if I put my hand in one side of the tank.
She doesn't care about anywhere else. This appears to be their chosen
spawning spot - I've found the odd egg in the substrate but no serious
activity. I've only had them since November and they were young when I
got them. The funny thing is that when "in the mood" both male and
female will attack their reflections in the glass - worried me the first
time I saw it but it happens so often now I'm not bothered about it
anymore. Pezemol recommended a brilliant book about Clownfish (thanks) -
by Joyce D. Wilkerson - makes a good read even though I'm not quite
ready to attempt to raise fry

PS When she does nip it hurts so definitely not recommended

Strange. It's the second time in a 24 hrs that somebody recommended
that book. I have it on my wish list now.
I'm going to attempt it when I get a chance. My clowns have snuggled
into their 100 gallon tank and seem happy. They slept on their anemone
last night and they are roaming the tank this morning.
I'll need to work on some food for them. So far, they have only eaten
flake.

What ambient temp do most of y'all keep your room(s)? I am on my
first reef and haven't started stocking yet. I keep my house at about
78 during the day and 75 at night. With halide lights, is this too
warm of an ambient room temp?
Thanks,
Dave in Simi
Wayne Sallee - 13 Jun 2007 17:16 GMT
I have a fan on my reef tank to cool it. The ambient
room temp, depends on a lot of factors, but I have a
personal rule, that the aquarium temp is ok untill
it hits 86. If it hits 86, then the lights go out.
If the air conditioner is on, then the air temp is
kept at about 80.

My personal rule is that if the rooms where my tanks are get too hot for
me then they are too hot for the tanks. Before we got the aircon I used
to have to run airpumps and vent the tanks by leaving the tops open and
turning off the lights (these were the freshwater ones). Observation is
also important. If the fish/inverts, and as I've just learnt corals,
start showing signs of distress and there is no other factor in water
quality then it could be heat.
This is my first summer with the reef tanks so very much a learning
curve. But from FW experience clear signs of oxygen depletion are the
fish at the surface and heavy gilling and I can't think it would be any
different with the marine.
BTW cutting the lighting and venting the tank by leaving the lid about
1" ajar has meant that the Nano only hit 82F max today and the ambient
temperature was higher than yesterday.

Because I use fans to cool the tank it depends on both ambient room temp
and humidity. With humidity in the 50's (%-wise) then the room temp is
around 77 degrees. I usually keep my house at 78 during the summer, but
I don't want the temp to climb much over 83 degrees.
I'm also away from home a lot, so the systems need to be automated. I
just invested in a 3400 watt standby generator which will keep the pumps
going for 24+ hrs (among other things).
