It's getting to be the time of year when I start wondering if I'm going
to actually buy a chiller. We just had our first heat wave & the tank got to 85 degrees. Being the cheap ******* that I am I was looking at DIY plans & found things like the small fridge mod, the old window a/c mod, & even the dehumidifier mod. Do any of those work (reliably)? Also, with my price range I think I'm looking a used chiller. Is that a reasonable choice? Or should I just buy a brand new one? What do I need to look for when buying a used chiller? TIA, Steve |
Chiller recommendation
Steve, you need to set up the DIY chiller using a window A/C unit. It is in the
DIY forum on RC, and it'll run you about $500 altogether. I know that is a lot of money, but this will last you MUCH longer than a chiller we normally buy. Plus the A/C unit is outside and you won't have any noise or heat issues from a unit in your home. Let me know if you can't find the thread.

the average temp of the reefs where most of our animals are collected from is
82 -88.. even in the winter months, only one reef drops below 80 and that is the great barrier ( we dont get any corals from the great barrier). If you would keep your tanks at the temp of NSW ( 84ish) a temp swing to 85-87 is nothing.. a temp swing from 78- 87 is a big swing.. the link I would like to provide is broken ATM but if ya can find aquarium frontiers nov 1997, a great article by Dr Shimek will have you keeping your tanks at a more normal temps.. Corals do much better due to the motabilism rates.. I have not seen a tank that _needs_ a chiller yet.. All summer long I kept my 120 surge/tide zone in a tin shed with 4x 400 halides over it.. No AC.. Outside temps would average 90 (or higher).. I had the tank set up so fand would come on at 82 and lights would start shutting off at 87. Lights only went off 2 times all summer, and I never lost anything. A few properly place fans will do the job, especially in an airconditioned house. Good Luck Rod Buehler www.asplashoflife.com |

No, I live in Southern California.
That's what I do every year with the fans. I'm just thinking it might actually be cheaper to run a chiller instead of two fans. And possibly quieter too! Rod, you were saying that your tank swings from 82 to 88? In my tank I have noticed at 83 & above there are some things I can't keep. Pocillopora & Stylophora are a few I can think of. I have a clam/sps tank. Mark, are you saying that the A/C mod is better than an actual chiller? At $500 for the unit you have a good start on an actual chiller (or a good used one).

I would simply use a good PC fan to blow away heat and suck in cool air. If
need extra cooling, use a house fan to blow directly to your tank. Central AC or windows AC will run up your bill. Your temperature should not be swing too much if you have a good heater that will turn on when temperature drop. My tank temperature constant at 82 - 84 all year round [Northern Cal.]. Most of the tank temperature will have a great swing if it located close or near a windows or to some heat source. CapFusion,...

downstairs but the upstairs is hell during the summer. Too bad it was early winter when I moved in. Had I known that it got hot as hell in the summer the reef would be downstairs.

I could ask the same question in regards to salinity. Most books I have read say 1.020 to 1.022 is the best specific gravity to shoot for, even though the nsw around natural reefs is 1.025 to 1.032 (red sea for the high side).

What part of the world are you from ?, I have several tanks here one being
salt water coral (upstairs) and salt water fish (downstairs) and the other is fresh water with fish. Day time temps of 30-40deg'C every day, night time temps from 24-32deg'C, and 2 tank do not have a chiller and the coral tank does, the two with out the chiller sit on 32deg'C during the day and 29deg'C at night. The coral tank is 25deg'C whenever the outside temp is below 34deg'C, higher then that the tank temp rises a deg'C for every outside 3deg'C increase. So a comment about not needing a chiller is silly, it may be the case for where you live, but certainly not where I live.

It's not bad 99% of the time. In fact, it's rather amazingly awesome 99% of the time. Santa Monica has the nearly perfect climate, IMHO. 50 degrees in winter is darned cold (normally 55-65 degrees), 90 degrees in summer is darned hot (normally 75-85 degrees). That, and while I'm pretty much temperature tolerant over a huge range, while my SO is very cold intolerant. The 1% when Santa Monica (and the no A/C) sucks is when a strong Santa Ana wind is blowing hot air from the desert across Santa Monica and out to sea. The rest of the time, Santa Monica gets nice cool breezes from the ocean to moderate the heat of summer and you don't notice the lack of A/C.

I dont have to worry about CCR's :D but I do know people that do, didnt know how they would go with a 12" duct, The aquarium is on the far side of the building from the crawlspace entry point (even repairmen going into the crawlspace wouldn't come across it unless they were fixing something in my condo). The vents in the sides of the crawlspace are 10"x6" holes in the stucco covered by grille's. There's no way to see the duct for the 10' it needs to run from the shaded vent I've selected to the spot under the aquarium where the chiller will reside. also I think id do that backwards if possible or it will heat your house It will heat the crawlspace, but the crawlspace has a lot of vents around the perimeter of the building. My current plan is to see if there's adequate passive flow to keep the crawlspace temps reasonable. suck the exaust air out of the crawl space otherwise it will get way past hot. If the passive ventilation of the crawlspace is insufficient, I will then try reversing the duct hookup, but because one of the vents will now be blowing hot air out from the building, it will become conspicuous to any pedestrian in that area. Which is something I'd like to avoid. If nobody knows, then nobody complains. If nobody complains, then my aquarium stays cool and I don't have to heat or humidify my condo to do it.

There is "No" way to retrofit a/c AND you are not "allowed" a window unit? Is this something unique only to California (it would not surprise me) or is this a typical condo thing? So no air conditioning at all is possible within the condo. What type of heat do you have? I'm bending the rules on allowed electrical equipment in the crawlspace, but if you don't tell, I won't... Regards, Ross Okay, finally I have something somewhat helpful to say... What type of clothes drier, if any, do you have? Maybe you could figure out a way to "TEE" in to the vent and exhaust through the drier vent. That way, no one would suspect anything if there was hot air coming out. Naturally, this solution will present a few problems but they can be overcome. -OR- What do you normally do to stay cool in the summer time? You might want to consider some window fans. If you arrange a couple to blow air in and a couple to blow air out on the other side, you can successfully increase the air exchange rate thereby reducing your high humidity. A couple of small fans on the tank in addition to this should solve your problems. hth ~Mort |

But we have a Maytag stacker if you must know :) The vent blows into the crawlspace because we're not allowed to have it... Yeah, things are pretty draconian. But it's four blocks from the most amazing job I've ever had and I can afford it, so... What do you normally do to stay cool in the summer time? Occasionally open a window. That's about it. Luckily, that's about all that's needed 99% of the time. You might want to consider some window fans.

This is true, but I'd like to be able to leave for a week during the summer and not have the aquarium fry while I'm away if the temp rises just as I walk out the door. I'm going to try several options. I'm pretty sure a chiller is going to be going in, with all of the ensuing cost and trouble. Thank you for putting some thought into it, though...
