If you're interested in solar gain for planning passive heating, this is a great tool for showing the solar irradiation on your property throughout the year. At this time you can see the solar gain is least. http://www.sollumis.com/

Perhaps they can put it in isolation for you until the fins have healed?

No maori blood in him?

Neat. Can lift up to 2000m so good enough for my home :slfg: Also used in nuclear facilities to move radioactive substances. http://our.windowfarms.org/files/2012/0 ... ftPump.pdf

One storey is pretty impressive for an airlift.

Any hydraulic engineering types here? Just wondering what the formula might be to calculate the maximum height of an uplift tube. I read that the pressure exerted volume of water in the tube should not be greater than the pressure at the tube's entrance, so a deep tank is capable of providing more lift than a shallow one. This is in relation to the windowfarm which uses uplift tubes to bring water up from a small container to the top of a window powered only by aquarium air pumps ...

So clearly you tap people are not having issues with chlorine? I read somewhere about 20% PWC with chlorinated water is supposed to be safe ...

Have a look at Dean Ornish's book "The Spectrum". He says dieting is not a morality issue, and not about deprivation. He's done pioneering peer reviewed work on life style modifications reversing coronary heart disease, lengthening telomeres ( thereby possibly increasing longevity ) and other things we thought impossible. President Clinton went onto his program and managed to get his weight back to when he was age 13. As he says "Sacrifice is not sustainable. Love is."

My green algae was untouched by the excel. If you only have few tufts, stop your power heads, and squirt the tank dose of excel directly onto the BBA using a turkey baster or syringe.

Looks like there is an aquaponics tag http://our.windowfarms.org/tag/aquaponics/ Some crazy/mad scientist construction going on here

BBA appears to flourish under excess lighting and nutrients. If you have a non-planted tank, then there's nothing to remove the nutrients except PWCs. I had a bad case of BBA a month or so ago and it seems to have come under control by frequent water changes to get the nutrient levels down, reducing the light to the tank and then using Excel. I had some driftwood in the tank as well that was covered in BBA, and I removed it, and put into another tank just with water and excel. I didn't want to kill my java fern which is why I just didn't sterilize the wood. It's been under a black plastic bag for the last month and the java fern is still alive, but the BBA is mostly dead now. Since the tank is by the window, some light does penetrate the plastic.

Guess that makes sense .. if you live near the airport, you have the best chance of getting out! Having a wetback around the combustion chamber seems to be a poor design because as you say, that lowers the energy available for combustion. The rocket mass heater mentioned above insulates both the first combustion chamber, and the insulates the chimney where the combustion of the gases occurs. The heat is extracted after the combustion has been completed by directing the exhausts horizontally through the thermal mass before venting to the outside with an exhast temperature of about 50 deg C. There are a few videos on youtube showing people using these to heat their glasshouses where they have their aquaponics setups. If it were legal, you could even direct some of the CO2 from the combustion back into the greenhouse as a form of CO2 injection. ( Greenhouses get low in Co2 due to lack of air circulation )

Guess the lesson is .. make sure all your tanks have lips, or, don't fill to the very top if you don't want to clean up a mess after a quake.

I read on stuff that it lasted 30 seconds ..but it felt more like a minute!

They should have different tests. For new burners that are claim to have no particulate emmission, they should just confirm that.

My dog is well trained .. he hid under the coffee table while I was under the dining room table! :slfg:

well, that was a long one .. about a minute or so. None of my tanks lost any water but they did get a bit of extra aeration with the surface agitation! Not showing yet on geonet.org.nz

I think the Koi were first poisoned and then the pond was drained. I've never heard of air needles so no idea of where to get those from. But Jeremy ( the Japanese guy ) looks as though he just threads the airline hose up the bottom of the aluminium tube.

An interesting variation called windowfarms .. see www.windowfarms.org http://www.atroxen.com/gallery2/index.p ... schau-farm Any aquarist would likely have all the gear apart from the hydoton or sponge. Instructions http://www.windowfarms.org/howto/3plant ... _27_10.pdf And just substitute an aquarium for the bottom reservoir. No need for chemicals then.

Cases like this make one wonder whether NZ should keep their double jeopardy laws which were abolished in the UK.

Could always blame Arthur Allan Thomas.

Koi have been found as far south as Nelson in a pond administered by the city council. Although considered a noxious species, they are alive and thriving in the National Aquarium in Napier though I am told they're not wonderful specimens in terms of colouration.

Are they at least going to charge him with arson?
