Yes thought about this as well.. but I don't actually mind the setup cost of a chiller.. or the pipework in ground for that matter.. but am more thinking of running cost (and the cool (no pun intended :lol: ) sustainable idea that it is). And as mentioned before I will probably be digging trenches around the house anyway. I guess I can try.... BTW I buried my temp logger at 15cm depth last night and during the last 24hrs temp has been steady on 17dg C. Will try deeper tomorrow.

Yes this is exactly what I was thinking Sorry but I don't get the idea with a drum.. With a drum there would not be much volume to surface area and as such would not be very good in getting rid of the heat. We are planning some digging anyway to put a coil drain around the house so was thinking to run the pipes in that trench as well.. (two birds with one stone) I'm sure it can be done but it's more the scale of it I am unsure of. Length & size of pipe etc.

Hmm interresting ideas.. I don't see why not? my drinking water comes in a pipe buried underground but yes maybe cleaning this pipe could be an issue. What I was thinking was to have a pipe going from sump to underground, running for x meters and return to sump driven by a pump connected to a thermostat. Once temp goes over 18dC pump starts... etc.. just like a normal heater but obviously the other way around. So question is how much is needed to keep say 400L at 18dC.. Off to gather some in ground temp data :digH: :slfg:

Toying with some ideas for cooling options... A chiller is obviously quite expensive and running it can't be cheap either.. so. Was thinking of burying several meters of pipe in the ground at x cm depth and then pump water through to cool it down. Has anyone got experience with this e.g. how much pipe at what depth for a certain size tank? The aim being to keep tank temp below 18dC year round. Any thoughts appreciated

Snowplanet carpark is full of alder trees. Not sure if time of year matters much... I collected a big bag full in november there.

I've had the same happen to mine a few times.. and they have come right every time. Just a scale that have come off or something. Nice moss wall!

Doesn't matter that it's ground floor.. it's still suspended over the ground. If you can crawl under the floor then find out which way the joists run(timbers holding the plywood floor) When you place the tank its direction should be perpendicular to the joists and cover as many of them as possible. Also important that your stand spread the load evenly across all joist. Forget about plywood or carpet or whatever, that does nothing structurally. So don't have a stand with legs. You need a stand that has a bottom frame that crosses as many joists as possible.. As for if it will actually hold... it probably will if you place the tank on an external wall (closer to where the joists are supported) and follow above suggestions.

Don't worry.. I think we've all done this.. I know I have.. But I didn't lose any fish though..

Looks like some kind of horrible mix...

Also called an amphibian

:sml1:

Just feed him the 60 tadpoles and be done with this frog thing.. IMO this is the most stupid thing you have wondered if you can feed your fish yet. But as you say... I wouldn't understand

Look closer young moderator and you will see little suction cup heads sticking through the netting.

Nice moss wall! :thup:

He did say "pressure cook" it... where you can easily reach 121 deg C. It is common practise in science to sterilise at 121 deg C for 5 min to be sure to kill spores.

Wow someone dug out this old thread.. No, I never came any closer to an explanation to this.. even with 9400 views on youtube, no one could offer any real explanation.. plenty of jokes though :slfg: But I can report that it no longer happens when I do waterchanges.. I suspect whatever fungus/bacteria or other organism that was causing this has now been outcompeted by a nice red/brownish algae/bacteria that the wood is now covered in..

Wow.. :nfs: Almost makes me want to go African!.......... almost

Nice! Where are you getting them from? These are the peru altums yes?

I like this... but.. Angel=Arowana food?? no?

Good link Ryan.. I found that I agreed with this quote:

Wow good value... does it say how many microns?

So I have just destroyed my most beautiful Kribensis male offspring yet.. He was an absolute stunner.. except he was born with a crooked mouth (where the top and bottom jaw is offset from each other). I did it because I think since natural selection doesn't play a big part in fishkeeping it is in the best interrest of this hobby to "weed out" potentially mutant genes like that. I cannot of course be sure it is something genetic. And then of course it becomes human selection (which really I'm against.. just look at how silly a goldfish looks!) The reason I'm writting this is because I'm interrested to know what other people do and especially what breeders do as "general practise" when it comes to selecting whether to keep a fish or destroy it? My wife said: "but it's so beautiful how can you just kill it? if you don't want it then give it to someone who does..." I think I should not give it to someone who might just breed it. Any thoughts?

Thanks for sharing Henward Cost and maintenance? (how often do they need cleaning and how)

Nice.. looks like it's heading in the right direction to me.. but yes more rocks and wood for sure.. Is that black west coast sand you have in there? have you used that before?
