Hi Aswin,

Congratulations on your decision to try iAVs.  

As much as I believe that you'll benefit in a very tangible way from your decision, I applaud your courage in becoming a member of what is still a select group of latter-day pioneers.  Most of all, I thank you for your wilingness to share information arising from your experience.   While we have assembled a useful parcel of infomation about what has already happened with iAVs, Mark is the first to assert that there is a great deal still to be learned....and people like you, Aufin, VKN....and a growing band of others...are going to play a critical role in building the body of knowledge and evidence that attends iAVs.

Gary

Thank you Gary...this is my 2nd Trial of iAVs soon I will convert my old 10m3 fish tank gravel aquaponics into iAVs.( after the comparing ends).within a week my iAVs water condition is far better than water from gravel bed aquaponics..and crystal clear water too...very much exited and going to build another trial with quarts sand for the first time...(now i used is river sand and water ph intact at 6.5)

How does your sand stack up against the recommendations?

If your sand is draining effectively.....and your water is stable at pH 6.5...why are you considering changing?

Hai Gary...I am not changing any thing in my iavs setup.Iam talking about converting flood and drain gravel bed into iAVs sand beds....I was realised that iAVs is the best bio filteration method now exist.easy way to produce organic food too... thank you Gary for Showing interest in my small setup...
