Carp Fertilizer

Hello,

Firstly, thank you Tom for hosting a fantastic forum. I'm a newbie to this whole scene but I have learned so much just by reading the forum over the last few days. It's amazing what you and your team and members have built here.

I'm amazed by the ingenuity of this forum and the effort and skill that has gone into this hobby/industry. It's interesting to read how people have adapted soil/plant fertilizers into the aquarium.

So here's my comment/question. Has anyone used or can recommend/condone the use of organic liquid fertilizers such as the ones based on Carp for aquarium use? I haven't read anything on the subject but rather curios on the matter. This is the contents of a generic liquid fertilizer concentrate sold at aldi at the moment. I suspect it's not a good idea at all, but thought it may be an interesting topic if nothing else.

Thank you Biollante, you described the manufacturing process pretty spot on lol... google charlie carp and check out the manufacturing process
Reading and learning from this website i canme to a similar conclusion, i.e how is the nitrogen made up. Would an ammonia test show whether or not there is excessive ammonia in the fertilizer? I guess the test would be to see how quickly that ammonia gets convereted and depending on the dosing strength, what the actual ammonia reading is.

I may expermiment with a planted quarantine tank that has no fish in it at the moment.

Having said all that, i'm going to be sticking with the EI method. I found an Australian supplier who will blend the chemicals based on a recipe i provide I just like to tinker and test... I should have been a scientist lol
