For my purposes chillers don't drop the temp as much as I would like for hot July and August days. That's why I plan to air condition my basement this year. The technology is changing and it might be cheaper to chill a tank or two. If the tank has any size to it or you have several tanks air conditioning the room is cheaper and more efficient.
I agree with Mike. It is often easier (and may be less expensive) to cool the entire room if you have multiple enclosures that need to be chilled. One of the big drawbacks to any sort of chiller is that these are made to exhaust the excess heat into the room (and usually very close to the enclosure you are trying to cool). In a small room or if the chiller is inside a stand under the tank can cause the chiller to work against itself to the point it is ineffectual. These guys are also energy hogs and often pull more than a room air conditioner.
I am impressed with cost of that chiller. I would want to do more research on the unit's specifications before I dropped $400 on it.
If I personally need a chiller, I would modify a minifridge by drilling two holes in the side and looping PVC braided poly tubing inside. THen use a powerhead type pump to circulate water. This method has got to be more efficient than cooling a whole room.
I use exclusively aquanetics chillers, we haven't had any problems and their support is great. I recently installed a flow through chiller on a mudpuppy tank that is exposed to a hot lobby area, and is right next to two 2hp pumps. I am glad I did because before I put animals in it the temps were pushing 80!
This method has been discussed to death on some of the old reef forums. The weak link in this type of home made chiller is the rate of flow inside the coils. The rate of flow usually needs to be very slow to drop the temperature of the fluid inside the tubes and to effectively transfer the drop to the aquarium. This is very difficult on bigger systems or when an pump that is cooled by the water passing through it (like your powerhead) are used. Plus an inefficent fridge is an energy hog and most of the inexpensive fridges can bump up the electric bill.
When you chill a couple of aquariums then a chiller isn't too bad but when you have multiple enclosures, it is easier to chill the room as the vented heat is outside of the room (unlike the chillers heat exchange which is still vented inside the room).
If you are handy with tools then another route to go would be to buy the coleman coolers with the built in chiller units and either replace the lid with a see through pane or cut and install a window into the side/top of the cooler.
Another item to consider is that chiller units for aquariums are not rated for their energy efficency (if I remember correctly) unlike window mounted ac units. (And for $400 you can get a pretty good window unit).
Hi I have 2 4in juveniles (I’ve had them about 2 weeks and they are doing well I think they’ve grown a little already honestly) but I am supposed to go on a 5-6 day vacation in October about 3-4 months from now. I am wondering how I should go about their care when I am gone. I thought about putting them in separate (fairly big) containers with live plants and/or bubblers with a fan in the dark and either fridging them (my last plan) but I am hoping to to either have someone I trust come feed them and turkey baste waste out or just leave them out and clean the containers before we leave and have someone come check on them once or twice. Does any of this sound like a good or bad idea? I want the best for them. All help appreciated
Hi, so I have 2 male axolotls and about an hour ago they were both perfectly fine and now only one of them has his tail curling up and his gills are slightly curled?? But other than that they’re both acting normally
Does anyone have any idea how to help with high ammonia levels? I have the API freshwater master kit and everything else’s test results were great besides ammonia. I did a 50% water change and I use API products including ammonia lock.
Help! I got my first axolotl two days ago and they have stopped eating. They ate a few frozen blood worms the first day and haven’t eaten or been interested in food since. I feed them frozen blood worms and the tank is around 64 degrees. I do have a filter that moves sometimes and I noticed them swimming up to it, I have a new filter and a fan coming today or tomorrow. I leave the worms in the tank or a little bit before taking them out so I don’t know if they ate when I wasn’t looking. I know it takes a while for them to digest. Does anyone have any tips or knowledge they can share? The pet store I bought them from didn’t have gravel or sand in the tank so I’m not sure if theres an issue or if I’m just impatient. Thank you!
@MuggleMiChu I would say try live black/blood worms untell they are full or just turn there head away ( that's what mine do) if that does not work try to get some live brine shrimp and see if they eat that. baby axolotl prefer live food over frozen food as the frozen food is too cold for them or they can't eat it in one go( that's if you do the blocks) mine eat chopped up frozen thawed shrimp. as for them not eating from what I have experienced with my second axolotl, I got her when she was about an inch long and she ate every day, when they start getting 3-4 inches long they will gradually slow down there eating. and if you really want to do substrate I would do sand because if they do ingest a little bit it won't hurt them.
Thank you so much for the information and advice! They are eating again, they ate a lot today. I think it might have been stress from the move or digesting old food, I also noticed they ate some of the food left in the tank (I removed the rest). I’m going to keep the tank bare bottom.
