Is a chiller necessary in Melbourne?

Recommended Posts

Just wondering if we'd need a chiller on our Mischling and CRS tank. We are in Melbourne and in the warm weather hubby likes the air conditioners left on 20-22 all the time, but I tend to bump it up to 24-26 when he's not home so we don't freeze. All the tanks are in the coolest part of the house as well.

I'm thinking we probably don't and probably couldn't afford 2, plus I'd prefer to get an RO unit first.

Any advice would be greatly appreciated.

Thanks in advance :-)

Ultimately if you are going to leave the air conditioner on when its expected to be hot then i would say no, but if there is going to be times when the shrimps tank will be exposed to high temps and force the water temp up then i would recommend a chiller.

 

You can also buy fans which blow over the top of the water and reduces the temp by a couple of degrees but when it comes to the crunch no where as good as a chiller or air con.

If you can afford a chiller then that is the best for overall stability but having said that I have 4 computer fans on my big tank and they keep the temperature between 22/23 . They work very well with a temp controller and that tank is against a wall in a corner which gets quite warm in the afternoon..

I have chillers on mine Jen but each chiller was around $400. For the size of your tanks it could be less.

If you are keeping aircon going, I wouldn't bother! Just be sure to check temps on 40+ days.

You can use frozen bags of water as an emergency measure. As others have mentioned, the fans can help too.

For absolute peace of mind, and if $ aren't too much of an issue, why not .... If the room/house is air conditioned there's really no need, but if you're on hols or headed out without leaving the AC on, the 1-2 days of over temp may cause issues ...espacially if the tanks are nano's... Fluctuates more readily. I have 2 Racks, and 5 nano's I'm a air conditioned room, and they All have individual chiller units :-(, lots if & outlay, but gives me dorm serenity when I'm out and can't get to my AC....

Yes! Yes! Yes! That's what my shrimps tells me. Every summer you'll have a week of 40+ degrees in Melbourne, which will kill off most if not all your shrimps.

Thankyou for the advice everyone :-)

Sorry it's taken so long for me to reply, but my notifications didn't show that anyone had replied.

I'll definitely be looking into chillers or fans for our tanks, after I finish saving for an RO unit, and can hopefully find something before the heat waves hit.

Luckily for our Shrimp we won't be going away over summer and I'll be keeping a close eye on the temp in their tanks. Hubby likes the air con left on 24/7, even when we go out as he believes it's more economical in the long run, so the room they are in should stay around 20-24 C. Unless something goes wrong with the electricity or the air con breaks down.

Well even if something goes wrong with your electricity it wont save your chiller anyway cause it would be affected. 

I had a couple of those days back in Sydney lol

I kept CRS in Melbourne with no AC or chiller from 2009 until this year when they all died during the summer. I was not managing the tank well at the time and the problem may have been averted if I had been, but the moral of the story is that you will need cooling of some type eventually. And a generator to keep the AC running.

Thanks guys :-)

Good idea Kizshrimp. You just reminded me of the portapacks we have up at the yard and only use to jump start the trucks or cars now. Think I better bring one home when it gets warmer, and keep it charged up just in case

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
