Backyard Aquaponics
A place to discuss aquaponics

Here it is: I installed extra GB and now ratio is 2:1 180L FT/90L GB

Can someone tell me why plants doesn't growing properly?
I lowered ph to 7,8, I have constant ammonia of zero at 22 goldfish, I added iron and salt, sun is reaching plants. What else should I do? My system is 40 days old.

what are you feeding the goldfish? flakes won't provide them or your plants with much in the nutrients department..
your system is still pretty new, and still cycling,, be patient

look on ebay for these or amazon

Yes I feed them only with flakes.I'll try find something else.And I would look for maxicrop.Thanks.

I have a problem. Today I found one fish death and the rest is sitting at the botom of FT.They look lifeless.Death one had a bubbles in mouth.Ammonia is zero, nitrates and nitrites is close to zero. Help.

Now I have only two survivors, everything looks bad.

what temp is water? and if it is hot where you are you may need extra air pump in ft

More grow beds, should be 2 of GB and 1 of Ft max I believe

It gets around 26,27C

I think that the plants are suffering from nutrient lockout - iron defficiency, that could be why the leaves look so yellow. You do have a relatively new system and the pH does generally come down as the nitogen cycle does it's thing. A scan of a pH chart will show what nutrients are available at a certain pH.

The bar indicating iron is minimal at a pH of 7.8. Hope this helps a little.

is that temperature the water temperature??

Yes it is.
