I have a 200 litre tank run by a 1500 lph canister and I am looking to get a chiller . Do I upsize it a bit or do I go for one that can cope with 300 litres or less? Is a 1000 litre overkill? The tank is in an airconditioned room but the corner it is in does get up to around 26 even 28 on a really hot day. I have been using computer fans that have worked extremely well  but think I should bite the bullet and get a chiller and don't  really know a lot about them.

I would like to have it set at around 23 but don't want to get something that will struggle and keep switching on and off .I have looked at the tables some of the online  shops and sponsors have but think I need a bit more help :unsure:

I think mines rated to about 400L my four foot is roughly 270L and it works fine, I've also got it hooked upto an 800L/ph cannister instead of my 2217 so the water gets plenty of time to cool, not that it'll be running for quite a few months. I think a 300L will be fine for you

G'day Ineke, I have a 200lt tank on which i run a Hailea HC 300A chiller with a otto 450g (1800lt) canister.    This seems to work fine for me, chiller is set at 23deg and comes on at 25deg and takes 15min to drop temp 2deg.  I hope this helps with your decision making.

Thanks for that Shrimp Aqua , Can you set it to come on at 24 when you have it set at 23? I guess I'm looking at a 2 degree rise and fall and wonder if that is too much for the shrimp? That's been my dilema with the fans -they work extremely well but I have that same 2 degree difference.

I was looking at the Hailea and the resun who both have the smaller chillers but had trouble working out about that lag in temp. Is that just the nature of the way chillers work?

Ineke, i have not tried at 24deg but i do'nt see why it would not work, i think it can be set with any differential you choose. i will check the booklet later and let you know.

Thanks I will be interested to see if it is possible. I thought you should be able to get less of a swing in temp than 2 degrees.

Ineke, the Hailea chillers use a 1 degree differential by default. So if you set it to 23, it will switch on at 24. If you don't want it switching on and off too often, make sure you get a pump/filter strong enough for it. I use the Hailea 300a and the Eheim 2217 was too weak for it to work properly. This is on a 200 litre tank by the way.

Thanks HeavyD . I will check out the specs on the Hailea again. I think my canister is strong enough at 1500 litres without being too strong to allow the water to be cooled. The 1 degree difference is what I had thought it should be. I think the Hailea allows your heater to be plugged into it as well? I want to make sure I get the right one - I tend to be swayed very easily and just jump in but I can't afford to make a mistake with this. I was lucky to have some good shrimp sales and have enough to buy the chiller but still need to watch what I spend.

Hello Ineke, sorry for the delay in getting back to you.  Heavyd is totaly correct in what he said, set at 23deg the chiller will come on when temp reaches 24deg.  It is my heater that is set at 25deg but never reaches this temp as chiler comes on at the 24deg mark.

 My appologies for any inconvenience

No problem, I'm glad that the swing is not so wide. Thanks for checking!

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      Thats a great photo, beautiful blue bolt, I hope it survived the molt without dropping the eggs! I think I can just about see some black dots (eyes) on the central egg but can't be 100% sure. I used to (and plan to again) do weekly water change of 10-15% but if you do too large or quick (not drip in new water) that would likely trigger a molt. What KH are they in, my new setup is sitting at (and refusing to budge) KH 3 and PH 7.5 so I may have to settle for neocaridina shrimp this time as opposed to the caridina I want, though not looking/deciding just yet, give the tank a bit more of a run in! Tap water here starts at kH 14, tds 320, when filtered goes to KH 0 and PH 6 but when put in the tank keeps going to KH3 and PH 7.5 despite 3 x 50% water changes???? You may be at 'maximum capacity' with only 20L tank especially if the tank is a cube type rather than shallow type?

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Right now this tank only has blue bolts and golden bee (red bolts?).  The eggs start off all brown, but at the end, I notice that some are kind of a clear pink-ish color.  So I don't know if that is the egg color of dud or golden bee.  Picture of shrimp only about half hour before molting. The water is always RO + remineralizer, so it should be ok. The tank seems to still be on a "good streak" ever since I started the regimen of weekly water change, monthly gravel vac and plant trim.  The point being to keep the amount of waste low and removing moss / floating plants so that the nitrates go towards growing algae.  At one point, I had three berried females, but only netted about half dozen babies by the end, due to this early molting problem.  There might be about 30-40 shrimp total in 5 gallons, but still very few full-sized adults.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      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.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      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.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      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?
