Aska Aquaponics 2.0!

After countless failures experienced from my previous setup, i decided to make a new one... The problem with my previous setup is that it was placed under a shade thus receiving very little sunlight and the pump was weak causing the siphon to fail frequently when it gets too clogged up... Due to its small fish tank size, water temperature and pH levels fluctuates a lot causing massive guppy deaths many times... Aeration wasn't good either...
Here's a pic of my first setup:

And now, presenting my second aquaponics setup! This time it's bigger and better...!
Here's some pics:

The setup was based on Affnan's Tilapia Breeding Homekit. The idea of using slotted angle iron as growbed stand was inspired from Mahfudz' aquaponics and En. Ahmad Hayan Radzi setup.

The pic above shows the growbed. The two small plants are seedlings of a nearby tree. I've also inserted a curry plant cutting there. Its difficult to root curry plant cuttings, their leaflets turn black if it stays wet for too long. For the purpose of this photo taking session, I've removed the plastic bag covering the curry plant cutting used to protect it from drying out.

The angle iron stand is painted with blue outdoor paint; Only on the outside! You can see the inner sides were still gray. The reason is the paint took too long to dry that i lost my patience and just went ahead to fix the stand. I may cover the stand with plastic sheet for extra protection later...

 Here's a photo of the "big" fish tank. You can see a lone Plecotamus (Malay: Ikan Bandaraya) by the dark corner there. That pleco has been with me since I first started aquaponics. I'm using an Astro 3000 pump which is very powerful so i have to divert much of the water flow back in to the tank. This will be room for Tilapias in the future...

 Here's the "small" fish tank. Those are my little guppies from my previous setup. They always rush towards me whenever I approach them as if they haven't eaten for days. This tank was actually the growbed of my previous setup. The overflow pipe in the middle was a standpipe previously. That green plastic bush ball on the right is a hiding place for their tiny fries... White stuffs at the bottom left are coral rocks to buffer the pH...

Oh look, the siphon is flushing!

I'll post an update soon... Thanks for reading!
