Indoor Veggie Filter with Goldfish Tank

Hi All,

Like to share with you all my veggie filter which has help to reduce my tank's nitrate level.

Thou it can't water changes, but would be good to cut down to one weekly change instead of twice weekly.

Bro thanks for sharing, looks like a 2-in-1 solution for decoration and filtration. May I know what sort of plant/soil is being used? Also, is it just a direct pump up to the plant pot and back to aquarium? Is everything DIY?

My 4ft (60G/240L) Goldfish tank is using Veggie Filter to help reduce the nitrates due to high bio-load from my goldfish.

Biological filter consists of 2 sponge filters and moving bed filter to handle the nitrogen cycle.

Overhead filter contain only cotton wool with no media for mechanical filter which is replaced weekly.

Veggie Filter contain 20 Lucky Bamboo + 1 Chinese Evergreen Plants.
I am using a 900L/hr pump to transfer water from main tank to veggie filter and the return line is via gravity through my 2.5" white colour water pipe back to my main tank.

With this setup, it can only helps to reduce the nitrate raising but I am still unable to maintain my nitrates to below 20ppm after 5 days. With this setup, my nitrates is hitting 50ppm on the 5th day compare to 100ppm without the veggie filter.

I do feed a lot to my goldfish, at least 3 to 4 feeding per day.
I water change 95% every 5 days.

To add on, no soil are being used.
What you saw in the tank are 2 lava rocks which I had thrown in which I saw from the internet may helps to reduce the nitrates.

Thanks for sharing. Very interesting setup. Have you tried experimenting with other plants that might be better at taking up nitrates?

Interesting that bio media can be used as "soil" for the plants. I may use 1 L of Seachem Matrix to use as additional bio media and nitrate reducers then.

I have tried money plant before, very good at taking up nitrates but just abit messy and dirty when it starts climbing up your walls.
So far chinese evergreen is my recommended choice.

Chinese Evergreen highly recommended to use in sump.
It's a plant with low light requirements yet fast growth.
