Backyard Aquaponics
A place to discuss aquaponics

Bit slow there Steve, thought you would have taken Mick up on it

BM hows the system going,I finally replyed in my thread to your ?s(been busy).
Did you get anymore hot days?

Coupla stinkers Gnash, cooling down OK now though. Pond is a multi-cultural centre - birds and bugs are drinking from my growbeds coz there's no other water nearby, dogs are sleeping under the pond and growbed table coz it's the coolest place around. Fish are getting a 50 litre top-up each day - I don't know which is responsible for greater water loss, animals or evaporation. :dog: :dog:

Just as long as they don`t get stuck into your beer supplies

dont forget Transpiration

Is that when the air-con on the train stops working ??

nah, its when we give you the bill for fix'in it

Aww, you wacky air-conditioner guys !!

I had 3 guys, took 2 hours to fit a Fujitsu split system - the bill ? --$880. About $190 / hour each - I'm in the wrong business !!

Did I complain ? -- boy, did I complain ! It did me no good, but these guys will never get to do another job for me !

hows it feel to be robbed in broad daylight

I'm comming to SA our price is usually about $700 takes about 4 hrs includes electrical.

Sounds like a bit, but when you consider COST price for 3/8 & 5/8 pair coil refrigeration pipe is nearly $20 per meter now and the sparky takes about $200 that leaves $300 (10 meter run) for a 4 hour job. And when you consider the cost of running a business (pay your own sickpay and holidays and super)..................

But still, $880 is on the pricy side

Makes me laugh when people say "but i can get it done for $500" (which they can) But then we charge $35 per kg of refrigerant and $77 p hour next year when the dodgy intall fails

Make hay while the sun shines steve(ya never know when you will need more AP stuff

or have a wedding to pay for

yeh, the wedding is how i justify working saturdays.............LOL

AM mentioned Transpiration as a water-loss cause a few posts back, and I didn't take too much notice at the time, but maybe I should have - nothing in my environment has changed too much, same temps, samne humidity (or lack of ), no leaks, but bigger, hungrier tommies, and I'm topping up at least 50 litres a day in a 200 litre system. All I can put it down to is Transpiration - any solid figures or educated guesses on this ?

Ummm...maybe there's some splashing? Or thirsty wildlife? I did a little searching and found a study on oak trees in Arizona. They estimated the average daily transpiration from a mature oak tree at 17.5 liters. Given that you don't have 3 mature oak trees in your system, I'd say that your water loss is from more than transpiration.
