Mini Aquaponics 1 Day 3

Did a clean of the aquarium today. Changed 80% of the water since it was murky white. Might have been caused by the cucumber that I was feeding to the sucker fish. After the clean, the water is clear again.

I've been germinating some seeds since day 1, decided to have a look at how its going. Oh wow.. the bak choy has already sprouted. That was quick, it has only been two days!

Bak Choy Sprouts!

A closer look at the little bak choy

Excitedly, I quickly transferred 4 sprouts into the 4 available baskets in the floating raft. Some of the baskets were quite high with water, I hope that doesn't drown my little bak choy.

Notice the raft is quite low into the water. I hope as the plant grows it won't sink further. Might need to add more polystyrene underneath it to keep it afloat. Fingers crossed.. :)

Mini Aquaponics 1 Day 2

Wanted to build the floating raft today, so went to buy some polystyrene and cups for the construction material.

Floating Raft Holes for cups

 Decided to cutout a few different layouts to see if there are any differences in growth. The four layouts are listed below:

1. Two small holes at the bottom and big holes on side
2. Single large hole at the bottom and big holes on side
3. Two small holes at the bottom and slit holes on side
4. Single large hole at the bottom and slit holes on side

Cut out some holes in the cups, 4 different cutouts

 Put some stones in the cups, placed it into the the polystyrene. Lets hope the polystyrene holds the weight.. Plopped it into the aquarium and the polystrene sinks half way. *phew* it works haha..

Floating Raft with stones in it

 Since the roots absorb oxygen, I placed the air stone directly under two of the cups to see if that makes any difference. But I wonder if the air bubbles are too big to be absorbed by the roots?

Under the raft, lots of air bubbles

Aquarium was setup using filtered tap water.
Air pump appears to be too strong for the size.

Air pump Specifications:

• Brand: Hailea
• Model: ACO-6603
• Power: 3.0W
• Pressure: 0.014Mpa
• Output: 3.5x2L/min
• Noise: <40dB
• Weight: 0.41kg
• Size: 110x70x160mm

After further reading, realised that it is recommended to use a one way valve to prevent water backflow into the air pump when it is switched off. A work around is to reposition the air pump higher than the water level. 

Completed Setup of Aquarium

After setup, I started germinating some seeds (Bak Choy and Coriander). I placed the seeds into a wet tissue and placed it into a resealable bag.
