My Ammonia levels are just going through the roof too! even though i have stopped feeding a few days ago

System is only about 2 months old.

Sorry to hear about the problems. If you're talking about the brown stuff on the side of the aquarium that looks like biofilm which is pretty normal and will fill in even more over time. Sometimes high ammonia can make the water look cloudy and that may be part of it as well.

If you have high total ammonia and the fish aren't dying it's probably because the pH and temp are low enough that the ammonia isn't in the toxic form. What are your readings for temp and pH? The chart here can be used to determine if the ammonia level is in the danger zone for the fish - http://ibcofaquaponics.com/information/tables-and-charts/

Hi and welcome to the forum

Do some water changes yesterday !!!!!!!

It looks like the bottom of the tank is dirty if so vacuum with a siphon hose as soon as possible

Need more info on system , fish numbers , growbed "Wet gravel volume" , how big is your pump ect .

I got caught in the beginning with not enough water going through my tank , fish waste was building up in my SLO , busy at work leaving in the dark getting home in the dark , high ammonia followed by a nitrite spike and lost half my fish.


Longer term you will need something to keep light out of your tank (To control algae) eg builders plastic between shuttle liner and cage , or wrap a couple of layers of 90% shadecloth around tank , lots of options .

Thanks Scotty435

Thanks for the assurance on the biofilm

my pH is about 6.8 and water temp is 12 at the moment.

Thanks Terra,

i think scotty has helped me..
my system is 2480 lt . The pump cycles the water at approx 1 time per hr.
On the base it is more like a film than waste build up . I have a swirl filter and bio filer set up as well.
I dont have much in the way of grow beds. i have a bit like an NFT set up mainly.

Based of that chart scotty referred to with my water temp so low and pH where is it at the moment it isnt toxic

thanks

Add salt. Plain NaCl. 1000 parts per thousand, or 2.5 kg per 2500 L.
The ammonia may cause a nitrite spike and kill the fish. The NaCl will protect them.

At 1000ppt your plants should be fine.

Best to add salt with as few additives as possible (no iodine or anti-caking agents).

>> Best to add salt with as few additives as possible

swimming pool pure salt is easiest and inexpensive - you will need at least 1kg, maybe more if fish start dying/suffering or you have to do water changes.

The muck (bacteria) is usually a sign of poor circulation / inefficient SLO/suction - or over-feeding (uneaten food)....
In cold weather the brown stuff builds up pretty quick and you don't want it.

There will always be small amounts on side etc but not clumps or blobs of it.
Particularly on the bottom or floating.

irrespective, with ammonia and nitrites up you need to be running your pumps 24/7,
Next question is how big are your grown beds - poor filtration is also an issue after circulation.
If nitrites spike you will also need air/aeration for the fish.

Image 20180706_171123.jpg suggests you have an issue.
It is coating the whole floor and SLO collection zone looks ineffective.

As it has come up so early and quickly, I would vacuum it out with a siphon pipe and redesign your SLO intake/pump.

>> On the base it is more like a film than waste build up
doesn't look like a film in that pic 20180706_171123.jpg

Thanks All for your help!
Been busy since i last pasted...

stopped feeding totaly for a few days.. the trout then finished off the gold fish :)

Ammonia levels are now on the way down...

The stuff on the sides was or is algae! Had a massive algae bloom..

Redone some of the pipework to allow for heaps higher water flow sadly not as neat as it was originally!
Painted the tanks where i could and installed shade cloth where i couldnt..

I thankfully already have a large airstone in each of the tanks

Guessing 1 reason for my algae bloom could be i only have 3 small plants planted in my system and my niratre levels have finally started to come up..

I think i also need to think of another way of getting the water to the plants... i made a small change and installed my watering pump in my sump tank and it doesn't have enough head pressure!
I have another pump but i think it will be too powerful ... joys :) will think up something
