Backyard Aquaponics
A place to discuss aquaponics

Don't mention it. i did say at the start of my thread that all the information i researched and developed, i will willingly display freely because i'm fedup of people hording information and not willing to share then.. and thats why i was away for so long. researching this aquaponics business.. i'm going on to 4 yrs since i started into aquaponics. Oh i'm posting a video soon to show how nitrates degas and how i add the ashes into the system. stay tuned

I like the idea with the ash. It seems to make sense.

Does it raise the PH up by much?

Oh btw Great webpage scotty435. here is a wonderful site that shows you all the full composition of the wood ash.. and as always Happy growing. http://www.peakprosperity.com/wsidblog/83690/uses-wood-ash

Lol... Colum lets just say the pH of wood ash range from 9- 12. and people actually uses it to make homemade soaps. that's how strong it is. youtube making soaps with wood ash.

Ok so this is the link to the video enjoy. https://www.youtube.com/watch?v=6llcMAON_A8&feature=youtu.be

Many Thanks and thanks for the links..

no problem I aim to please.

Good website cookie. I do have to wonder about the heavy metals and arsenic in the wood ash. It's less than many fertilizers though. On the other hand, some of the levels are higher than EPA action levels for drinking water. To add to the confusion much higher levels in regular fertilizers aren't considered to be a risk . Maybe it's the form these are in that makes them safe .

I knew that thiz information would of flag some alarms.. but thats why I stressed on what type of wood u used.. obviously if the tree grew in a highly polluted area there will be higher contaminants within to tree compared to one that grew in the rain forest.. the source of the wood is the key.. also the area it was burnt in can lead to cross contamination as well.. luckily where I live being the Caribbean we don't hada worry about these pollutants.. and even greater advantage is that my family business is timber sales so getting scraps to burn on the spot is quite easy for me... so I stress on the type of wood burnt will directly affect the purity of the end product..

There are also wood that are chemically treated to resist rotting anf pests.. burning these can also lead to pollutants.... starting the fire with accelerant will lead to residue in the ashes... there is alot of factors but normally if u create the ash personally u basically factor out all the variable..

Wood fired pizza oven?

That makes sense cookie. I'll probably stick to something with a known analysis, given that I have the option here and it's tough to know where and how a particular tree was grown.



Now there's a thought

wood fired ovens are perfect.. we consumer the wood so the ashes should be of standard to be ok for food application

lol I meant to say we consume the food cooked by the wood... typing is hard work.

Hey Cookie, great idea. Can you explain what you said here?
"but so far my addition is 5% weight of my day fish food input I use as ashes.. no be calculation I just choose the number to trial "

Think I get it but not sure.
