diy aquaponics for beginners | Aquaponics Tips Too High Water In Growbed

diy aquaponics for beginners


What will happen if you have too high water level in the growbed?

Initially high water level will cause higher evaporation and water will be use more due to this. To ensure this dont happen it is recommended that the water level is at least 1 inch below the hydroton or media level.



Above photo the water level is about 1 inch below the hydroton and it is just nice for most setup.

What else could happen?

Algae and some time moss will grow, moss could turn into fern in some cases. Algae and mosses will compete with plants for nutrient and it also will make the growbed looks dirty as below.



As a general rule 1 inch water below the media is acceptable, this is the DryZone of an aquaponics growbed. This DryZone can be thicker depending on type of plants grown.

A siphon with adjustable standpipe height is helpful in ensuring this water level is easily achieved.

murray hallam diy aquaponics | Water Flow Gauge

murray hallam diy aquaponics


Making this simple device to measure water inflow to growbed. This is helpful since I can then document siphon water operating range. which now is not so accurately done.

I use the Bettas BT 6000 pump as the water source and a mechanical flow rate gauge utilizing float type weight to shows water flow rate.

Two stop cock use, one as diverter and the other just to provide restriction just incase the diversion is not enough.

Below a short video presentation of the flow tester.

diy aquaponics fish tank | Potted Media Water Level

diy aquaponics fish tank


Slotted Orchids pots that I use for growing made it very convenience to adjust water level. Since some plants require different water level, with individual pots it can be adjusted to suite the plants that in it.
These pots has good drainage and I can easily adjust its level within the growbed to suit what ever I plant. This pots are about 6" across, therefore larger plants will not be suitable.
Shallow roots plants like Strawberry, Chives and leafy vegetable is best to use these pots. At certain stage of their growth water level may need to be adjusted to ensure they grow. Especially after transplanting where water level are normally set to high. With many plants in a growbed, adjusting the growbed water level will affect all plants in it.
Having individually potted plants in the growbed, it then can be position higher or lower within the growbed to get water level as required.
Strawberry as above was just transplanted, so the water level are adjusted to be high with pots burried deeper in the growbed.
Plants like Chives, above dont require high water so I adjust the pots to be higher up making the water level relatively low.
Above is a simple illustration on what I do to achieve different water level for individual plants within same growbed. This I find easier to do since pots containing the plants can be lifted without stressing the plants much.

diy aquaponics swirl filter | Siphon Operation Water Range Check

diy aquaponics swirl filter


It had been many years that I use the 25mm or the 1" stand pipe siphon with 50 ~ 25mm reducer as funnel and lately I had switch to 20mm and 15mm siphon for my setup.

The 25mm siphon still relevant but since more parts needed for it and the sheer size make it expensive to make and ship.

Few of my earlier growbed are still having the 25mm siphon installed and since Im phasing out this size, it will be a good time for me to check exactly its water inflow requirements. This to document for future reference or if anyone interested in making one then they will know what needed to be done.

Water inflow is the amount of water going into the growbed, it is not the pump rating. This inflow will depend on pump rating and how high the water needed to be transported up into the growbed. Water inflow means water "On Tap" that is going into the growbed for this test purpose and not the pump rating.

I uses a Rotameter, which is a very simple float type flow meter to check the water inflow to the growbed. Though it is not that accurate as an electronic meter, but for a simple experiment suffice.


I am testing four siphon and will get the average water inflow to trigger and stop the siphon. Setup for the test is like photo above, I am using an old pump that only capable of supplying inflow of up to 1200 liter/hour. It is sufficient to do the test with this capacity.

Those four siphon tested started at a minimum water inflow of 100, 250, 100 and 200 liter per hour due to their different outlet configuration and their condition, which already in operation for almost two and a half years.

The average for above is (100 + 250 + 100 + 200) / 4 = 162.5 liter per hour



The siphon able to cut-off at a maximum inflow of 650, 700, 800, 1000 liter per hour, again due to their condition and outlet configuration.

The average for above is (600 + 700 + 800 + 1000) / 4 = 775 liter per hour.



To get the sweet spot on what is the inflow for this siphon, it will be the mean of the two average at (162.5 + 775) / 2 = 468.75 liter per hour

I recommend the 25 mm or 1" siphon with a funnel uses inflow of about 450 ~ 500 liter per hour. From above test anything above 250 liter per hour will do, but we will need to give some margin for pump deterioration. 450 to 500 liter per hour inflow at the tap should give good result.

To know how much water flowing into the growbed you have to measure the water head, ie the height water transported up as measures from tank water level. You then need to check the pump rating as given on the pump write up as example below.



Table above, if your growbed inlet is one meter above the water level, then the recommended pump for the 25 mm siphon should be the AS-1000 pump. It is not exactly at the 450 to 500 range but its more than the minimum inflow as tested above. It is okay to use a bigger pump like the AS-2000 in the diagram above, you will then need to divert excess water away from the growbed.

The above finding serve as a rough guide, and by no means define exactly the size or type of pump needed. Your installation may differ but as a ballpark figure, the above estimation will do.

diy vertical aquaponics system | They Are Always Hungry These Tilapia

diy vertical aquaponics system


No matter how you feed them, they are always hungry. Tilapia has short digestive track they eat a little bit at a time but most of the time.
These are in my CRAFTS set, and they are getting bigger. I use fish pellets to feed them.
Never over feed fish, especially in Aquaponics. Water will get murky and Ammonia will shoot up. If you see foam or bubbles in the fish tank just stop feeding them for at least one day and continue after water had cleared.
Its okay for them to go hungry, they will start to feed on the algae making water and tank cleaner.
Surplus greens is good, above is the Sambung Nyawa plants that I cut and throw it to give them something to bite.
Tilapia will eat greens, one of the best is Kangkung these they will nibble in no time at all. However before feeding them greens make sure they are really hungry.
There are loads of green from my Aquaponics growbeds and its fish food.
After 1 day in the fish tanks, this is what left of the plants. Those stems can still be use as cuttings.

diy classroom aquaponics | Water Storage

diy classroom aquaponics


Water Storage is probably the most important item in your survival preps!
without food we could survive up to 3 weeks, without water we can only survive 3 days!

Why would we need to store water ?
well a natural disaster could break water pipes, or a contamination at water source, or even a pandemic where we were told to stay indoors and self quarantine.
In any of these events the stores would be crazy and empty supplies in hours, plus the last place you want to be is putting yourself in danger around desperate people.
thats why you need to keep an emergency supply of water.

How much do we need ?
The recommended amount is 8 glasses of water each per day, also we do get a considerable amount of fluids from food and other drinks, this all counts.
So on average it is recommended that you will need 1/2 Gallon or 2 ltrs each per person per day!
Minimum 3 Days for 4 People - 6 Gals or 24 ltrs (10 fruit juice bottles)
 Recommended 7 Days for 4 people - 14 Gals or 56 ltrs (24 fruit juice bottles)
 Very Good 30 Days for 4 people - 60 Gals or 240 ltrs (100 fruit juice bottles)

How long can we store it for ?
I always say if in doubt boil it! but i change my water about once a year, I use it in my water barrel for the plants and just refill, I do not use any stabilization, although  a droplet of clear unscented bleach in a 2ltr container is safe for consumption and will stop algae or bacteria growing, if you wanted to store it for longer.
Ideas for water storage in an apartment. keep water in a cool dark environment like bathroom, a cupboard, under the bed.
2.4Ltr fruit juice bottle makes ideal storage, very strong and easy to stack good seal on lid.
Milk container, is a good starting point but not very strong tends to leak and breaks easy.
These are much stronger and good seal on lid but not much storage capacity difficult to stack,
Wine bags from either box wine or in this case as you see it! very strong, dispenser valve for when pouring, very stackable, and great as spares, washed and stored flat dont take up much room and can be filled quickly. also in case where you had to leave your home in an evacuation these could be taken along with you and filled at destination or along route. keep 4/5 in a BOB ( Bug Out Bag)

diy aquaponics perth | What Happening Today

diy aquaponics perth


Apart from doing the racking.. as earlier post : Here

Few seedling needs transplant and rear growbed redo to after few weeks of neglect.
Eggplants above dont look healthy, these need urgent attention !! Transplant three of them into individual hydroton pots and place it in the growbed where the Sambung Nyawa are located.
Will see if they recover into healthy plants in a couple of weeks.
After the eggplants, Tomatoes that I transplant last week still has few more of same batch and just re-pot a few and the rest has to be wasted due to overcrowded.
Nothing interesting, just a normal day at the Aquaponics.

diy aquaponics filter | Fresh Water Red Claw

diy aquaponics filter


Visited nearby aquarium shop to get some fish for my Ornamental Set Prototype No. 2, so happen that this place stock many of these Red Claw Crayfish of various sizes. Price range from Rm 4.00 to RM 10.00 each. The smaller one at RM 4.00 is a good buy, but I refrain from getting any because I am not prepared for these yet.

Below are just some photos of those Red Claw for show.
