jim from kangaroo ground fish is selling out he has only 2000 silvers left 4 to 5 in about $2.00 ea will be all gone by xmas if nobody buys the business it will be all broken up and sold nows your chance

you beat me to it F&F, i was busy buy doing heat exchanger calcs for you!

At least you got your priority s right

I really should get organized! They are cheap!

The local pet store has got some in and I was admiring them, they are only about 2 to 3 inches and they want about $10 each for them!

They can't work out why no one will buy them! I asked how much they were when they first came in and the assistant asked me how many I wanted so I said "If they are the right price, I'll take the whole tank full." (6 or 7 of them) Needles to say, she was disappointed when I told her she could keep them!

lol, yeh the ones i got for 80 cents each were about 2 inches, the next day i saw them at the aquarium for $9.95. ROFL.

I understand markup, but 10x

lol, they also had a 500gm barra there......................$59.95 felt like saying dude, i can get this cheaper at the local fish monger

Sounds like maybe one of you guys (or all together) should buy the shop and convert it to AP propoganda

I see your barra and raise you to $300 for 8 inch barra!

They can't seem to sell them ether! lol I wonder why!

i saw a guy buy a rediculously expensive barra from a petstore the other day....so some people do buy them

i imagine they would.

Makes you wonder, the heating would be worth it if you could sell them for 1/2 that.

A little tank of barra might be worth a try....... 'course the goldies wouldn't like 'em! lol

DH likes the idea of barra too. This could be a plan.......

Monya did a load of barra last year....and kept us amused with all there antics

i recon if people want to run cold water fish in a warm climate or warm water fish in a cold climate the only way to do it economically is to have a 2 tank system, one in the garage or something, well insulated and CLOSED off to the GB's only running a biofilter. Then once per week (or whatever amount of time it take for the nitrates to max out do a 100% water change to the rest of the AP system.

That way you will oly be inputting p[ower to cool or heat the losses to ambient (low if well insulated) and the weekly 100% water changes.

if you have to raise 1000l change out water by say 5C it would take about 2.5 hr and around $1.10 with the system i'm doing.

Is that $1.10 a day

No, per 1000L change out of water if you have to heat it up by 5C

So in guess it depends on how often you have to do the 100% water change.

$1.10 per 1000L water change + the daily keeping it warm cost.

i couldnt give you a figure on the "keep warm" cost becasue it depends on so many variables, mostly how well insulated your tank is.
