Hi all you hill stream experts /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
I have been asked to help with a tank for the reception area of the offices where i work, we are a salmon farming company on the west coast of scotland and the most appropriate residents of such a tank would seem to be juvenile salmon. The idea of the tank is to celebrate the species we farm for the incredible fish that they are but also to draw attention to the collaboration that our farm has with hatcheries that restock the local rivers with wild salmon parr. Ideally we would hope to get a handful of wild origin juveniles from them so that when the time came to be released we could do so in local rivers.

i have only ever kept tropical freshwater fish, so am a bit of a novice when it comes to setting up tanks that would represent the scottish west coast 'hill stream' biotope. i need to look into getting chillers and power heads to create current.

i hope to keep a photo diary on here as the project progresses. Any advice on how to put such a tank together would be much appreciated /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" />

Hi Dave

Think I'd be tempted to copy the types of tanks used for the hillstream loaches with the pipes under the gravel... and yes, a big chiller. They are not cheap to buy and not cheap to run either /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

have you heard of Clyde in the Classroom? My 8 year old just finished a school topic about the Clyde and part of it was to get a batch of trout eggs, hatch them and eventually release them into a local burn to make their way to the Clyde. The kids got a huge kick out of doing that and learned a lot about life cycles etc in the process.

They also needed a chiller but adopted for a 2 tank method where bottles of frozen water were constantly replaced in tank 2 to keep the water cool in tank 1 where there was a flow through system... cheap and easy but not very practical for you! /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

hi colin, thanks for the advice, can you recommend any suppliers/brands of chillers and designs of systems that i could copy

i'm thinking of a 4ft tank with a sump filter,but will that filter set up just increase the volume of water that needs chilled?

possibly a simpler system with a simple external eheim 2217 and power heads in the tank to create current? or does that sound hopelessly underspec'd

my kids' school also did the salmon egg hatching program, only a few alevins hatched though in advance of the easter break (i think the chiller was on too cold), though i understand they have now been released into a tributary of the River Lochy. its great that the fisheries' trusts are getting involved with schools, cultivating the next generation of fish geeks /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

"cultivating the next generation of fish geeks"

yes, but a tad embarrassing when my daughter corrected me when I called the alevins "fry"!!! LOL Silly Daddy!

Only time I have used chillers was with a large marine tank I helped maintain and he used two Aqua medic Titans, but which ones I can't recall.

I believe you first job would be to set up a tank and see what the ambient temperature of the water is - bearing in mind that the powerheads/filter will also generate heat and then work out what is needed to get the temperature down to where you need it. I think its worked out in BTUs like a fridge?

I have hear of people scrounging old beer chillers from pubs. I got my hands on one once but never set it up on a tank.

Chillers aren't cheap mate - how cold are you looking to get the water?

Link here to some your looking at £300-500 to get the water down by 5-10 degrees C (ish)

They cost an awful lot to run as well - might not be an issue if it's for your business?
