I've seen the hanging method use by http://brightagrotech.com/home.html since it's useful for urban setting. Recently I have dismantled our aquaponics system at home due to avoid hazard of aedes mosquito breeding there because of the water in the growbed. There have been several death from denggue fever in my neighbourhood and I don't want to contribute to the risk of death to others. Although health inspector have checked my system and found no mosquito larvae still there's a lot of place the larvae could hide.
The hanging system of by brightagrotech to me seems like a better option since the water flows cascading inside the tower and there's not much tanks with water collecting inside. Living in Malaysia it's sometimes near impossible to find certain components at my hometown. For example Leca are not available in any shops and although I could travel to the capital to look for it the price is very expensive. So I need help or advice to look for this component which is a PET(Polyethylene terephthalate) fibre. I want to try making a similar growbed like the agrotech system as shown in the video link below:

The closest picture I could find online is this:
I'm not sure if I need to order the fibres custom made from a recycling factory. I could but it'll take time and money. But if there's already a product maybe like sponges or scrubs available in market, I could just use that. Really need help on this, leca is out of the question and normal aggregates pose as structural hazard to my parents, had a storm earlier this year and and half of the aquaponic roof frames were broken off.
Thanks in advance.
