Welcome Bakir.

I believe you mean what extra nutrients do the plants need.

Like many things to do with AP it depends. With a good quality fish food many systems especially in the first year need chelated iron and some need potassium. Poor quality fish foods have often been reported to lack a number of nutrients and cause problems but I've never used poor quality food so can not help you there.

yes imean that but please check this site talking about adding banana peels etc

Not something I have done but it is often advocated because it is believed to add patassium.

i think you mean that many of aquaponics owners dont add any elements to their system as plant nutrition..

thank you

Actually many do just not much or many.

Low iron can be a problem in new systems so many people add chelated iron as required. Low patassium can be a problem particularly if you are removing the solid wastes from your system.

Sorry i forget to add

I would never suggest burying organic matter in the growbeds, better to keep them as clean as possible.

Well let's say that there is a natural pool of water and there is alot of fish eating natural food no body feed them and we put water pumb and connect to aquaponics system ,will that water enough to grow the plants normaly ,if not what will we need to mix with that water.

No not likely to.

Currently is the is the fish pond clogged with alage and water plants?

If yes then by ripping out all those plants and giving the pond a good clean (which the fish really won't like) and having your AP system ready to go you can transfer all that wild growth in the pond to cultivated growth in the GBs.

If no then there are not any excess nutrients in the system with which to grow the fish. You can still do it but you will have to add the nutrients either in the form of fish food or as supplements.
