1. The Practical Aquaponics discussion forum has been in operation for the last 5 years...

    We have enjoyed giving this service free of charge however ongoing increasing financial costs of running this service is making it increasingly difficult. Up until now we have resisted advertising as a means of a revenue stream to help run this forum but it has become inevitable that extra revenue is required to run this forum.

    We have introduced a donate button to help offset the cost of running this forum. It is completely voluntary, but if you would like to donate, all donations would be greatly appreciated.

    Thanks Murray..

    I've heard that rock minerals might be good for the system has anyone tried this? Can it potentially hurt the fish?

    I just started my system a month ago and my lettuce has some brown spots and some yellow leaves towards the center, nitrites are just a tad high but I'm getting those down, added some earthworms a couple days ago too hoping they might help. Any help would be much appreciated :)

    I use rock dust when I set up a new system , ive also found scratching a bit in around plants like strawberries that show deficiency but ive never been able to work out which one , the dust solves the problem , don't know how cant be much instantly soluble material in crushed rock but there you go .

    Potential problems if used in excess will clog growbed (need a lot for that)

    I think the main issue is the copper and zinc levels which can be toxic for fish so read the label.

    I believe the product I use provides a good spread of base minerals that slow release

    New systems take time to build up a nutrient base , same as starting a veggy patch in a gravel driveway so make sure your using quality fish feed (not much nutrient for plants in goldfish flakes for example)

    Usual deficiencies in new systems are iron , potassium , magnesium these can swing around a bit depending on your ph .

    How often do you need to clean a growth bed out or do you at all?

    Grow beds can need cleaning
    If you have high fish loads
    Make sure you have worms in your growbeds to help deal with fish waste and dead roots ect.
    Ive done mine a couple of times the last time because I moved 700kms
    Previously because I had lots of plants with massive root balls (these can become "Dead" zones)
    I plan on probably cleaning out every couple of yrs if needed

    They will breed up toss more in , if you have too many they will just leave when they get hungry

    Think eco system. Everything we can use to our advantage evolved from. Water, minerals.
    With Aquaponics its incredibly impressive naturally but their are a few minerals that wont develop naturally in that eco system so you can help it along with ?? Iron, calcium in Lime or Dolamite.

    Hope you're right about the worms , I'll be in the dog house if not hahaha. I have the system doing 10 minute cycles hopefully that's slow enough.

    I just did a water change because the nitrates were too high, leaves started yellowing, I think maybe there are too many fish in there? Is it 1 fish per 5 gallons of water? Sorry how many liters per fish I'm from the U.S. where we are confused about measurements but that's a different topic haha.

    Leaves yellowing is more likely to be a deficiency of some sort - what are your test results for nitrate levels etc? And can you post a picture of the affected plant(s)?

    Leaves yellowing? Not usually from too much Nitrate.
