Hi All,

I have a small scale system here in the UK. 3 X 70 Liter IKEA tubs for the fish tanks with 3 smaller IKEA tubs for the growing bed. Clay balls as growing media.

3 Small pumps feed the tanks for 15 Minutes every hour and LED 300W light set on a 12 hours timer.

So far I have had 3 large lettuces out of this and now have some Chilli's growing nicely. Shroud be ready to pick any day soon.


Tank 1 Has 1 5 inch goldfish. Been running for 6 months.
Tank 2 has 5 X small gold fish. This is currently cycling so nothing growing as yet. Will be used for herbs.
Tank 3 has 2 medium Fancy goldfish. Been running for 6 months.


PH is and temp is measured via an Arduino.


I would like to have more fish in the tanks now they are established but do not want to crowd them too much.

Thanks I wish I did not have to have it in a tent but the light is soooo bright in my office and the neighbors would start thinking I was growing something else.

May have to think about some smaller white lights instead of the mad purple.

pretty hard in a system that small. At end of day a small water volume with 3 small tubs is probably going to be very erratic and only ever suited to a couple of fish.

If you are flood&draining then it must be hell in there for the fish.

One option might be to try and find a larger tub for the fish in the 200+ Litre size and then promote the fish tubs to beds. Try a builders tub from a hardware. That would give you a slightly larger system in pretty much the same space. You little trays would make good DWC's.

Hi Darren,

Thanks for you feedback. I will be updating this to a 600 Liter tank I have found that will fit in the same space. Is there any benefit in using the larger tubs for the growing bed rather than the ones I have now.

At the moment its about 30 cm deep but I can reuse the old tanks that are more like 60cm deep.


A bigger tanks will mean happier fish and easier to control the water ph I imagine. I am still very new to all this :-)

Would it be worth reusing the 3 old pumps and time them to flood one bed at a time instead of getting a larger pump to do all 3 at once. Would this help with the fish stress?


Thanks for your advice new pics will come soon once I have got the new tank up and running.

I took you advice and modified a 1000 Liter ICC container into a 500 Liters (450 of water).

It uses the same floor space and fit perfectly in my tent. Here are some pic including the chili and tomato plants
