Hi Murray

Have finally gotten started on building my system. I have decided on a CHOP system with a little over 2000 liter fish tank. Am trying to size the required grow bed size. I understand the concept of having an equal grow bed volume or greater than the fish tank. My question is when considering the GB volume, is media included or only water volume?

Murray, since we in Bermuda solely rely on rainwater and R.O. systems for our drinking water, i have virtually no buffer in my system. Any suggestions how to boost the buffering capacity. I have tried well washed beach sand, and I use hydrated lime as a ph up along with potassium bicarbonate.

in your instructional video you recommend the bell for the bell siphons be 2 1/2" in diameter which is near impossible to find in the states - I am thinking I will have to go to a 3/4" upstand and a 2" bell - think I'll be ok?

Hi Murray,

I finally starting my aquaponics project.

As I live in Dandenongs, Victoria, I am currently constructing a greenhouse to control the temperature during winter. I am intending to use a compost pile to heat the greenhouse during the colder months.

As I intend to have the greenhouse sealed during winter, it occurred to me that I need to consider pollination. How would you suggest that I address that issue? I know you have greenhouses but I think yours are open being in Queensland, you have a better climate.

Also would you recommend that I use Trout first up or go for Silver or Jade Perch?

I am basing my unit around your Indy 11.5, I got your book a while back now. I have to slightly modify it to suit the site. Once I perfect things, I will duplicate it.

Thanks in advance.

Kevin.

Hi Murray, we're looking into setting up our first aquaponic system and would like to begin with an ibc chop 2 system. Does the diy aquaponic dvd have the plans for this system?
