chelated iron is fine in AP systems, follow the directions on the pack

no not really i problem as far as i can see, but there numbers are growing.

EllKayBee the won bok pictures, there looking yellow with dark veins.

ok will get some chellated iron and see how that goes, much appreciate the feed back.

We are certainly out of synch here...
chelated iron for iron deficiency...can be bought at "B", I put in a spoonful (5g spoon comes with packet) once a month for a 1,000 litre tank.

Some of us are also trialling MinPlus (mineral dust with all the trace elements), not sure if that is avail in Canberra

See what others think about what is missing

Edit: that should read 5 gram size spoon measure - not 5mg, have changed it

thanks very much, i will be off to "B" tomorrow. Cheers.

pah , I was referring to what pic are the flies in...

Just buy some chelated iron from a nursery or hardware shop. It comes as a powder, just mix a bit in some water then pour it in. It's a fairly common deficiency for AP but easily fixed. You may need to add a little from time to time. It's safe for the fish, and for you.

Oops, I didn't see there was a page 3 and it had already been answered

SOK KE....done the same thing many times before

no thats good i was wondering about the fish, i assumed it would be fine considering it was suggested but you know what they say about assuming things.

and just to catch up a bit, sorry no pics of flies. i am pretty sure i know what they are but cant remember what they are called, in the fly stage they are ok but in the larval stage they eat your roots and slow if not kill seedlings, but thats soil based.

Go pah! nice to see some growth! Are you growing under a standard furo tube? let us kow if the iron doesnt fix it, i always find that the std. fluros leave the plants a bit wanting.................

A tip with the pics, add them in the reverse order you want them to display, just a qwerky thing!

Here is a site for flies Hover flies

at the bottom of the page you can then look at other types of flies

Hover flies are good flies to have, they are aphid predators

thanks for the tip steve, yes they are under standard fluro lights, i know its not perfect but fine for now. i do have a MH and HPS light but considering its in my bedroom it might be a bit bright for me, although i could do with a few extra inches in height! ha ha.

thanks for the link EllKayBee i will check it out, i did have a few aphids a while ago which i havent seen since i saw the flies.
