Hey everyone. Just curious about what peoples opinions are about this idea Ive been having for my tank. I have been reading that some folks put compost in their tanks substrate mixture at set up to boost growth in their tanks. This made me curious about the idea of using compost tea instead. If you arent familiar with the idea of compost tea you can find details quite readily if you Google it, however the concept is pretty simple. Put compost in a muslin bag, tie it off and hang it in a bucket of water. This allows the nutrients from the compost along with its trace mineral content to be released into the water, later to be used by gardeners as an organic replacement to chemical fertilizers. I want to skip the bucket step and just hang the bag over the side of my tank. I have a worm bin composter in my home that I have been using over the course of several months. The compost is made up only of vegetable waste from our home along with coffee and tea ground and egg shell for to neutralize pH. I suspect that my compost may have a low pH from the coffee grounds. However I think that this would be a non issue being that there would be only small amounts of compost in the bag. While definitive parameters of the compost in terms of TM, NP K are unavailable due to the drastic quantity of variables (foods introduced, amount of off gassing for N, so on) Its been consistently shown that vermiculite has a lot of minerals in it that are freed by the decomposition of plant matter and the digestion process of the worms. I like to ere on the side of natural as opposed to chemical treatment for my plants/fish. At the moment I rely on my fish to produce enough waste to feed my plants, however (as I'm sure that you all know) my growth is very slow. I have a 60 gallon tank but probably only enough stock for a 40 gal. I'm not interested in buying a bunch of fancy equipment or fancy ferts. Stock list: 7 serpea tetras 10 (approx) white cloud minnows 3 Rainbows (not sure type) 10 burma/zebra danios 3-4 random orphan fish 3 albino corys 2 albino hifin pleco Plants: Anubius Nana Anubius Barteri (I think Im right on those two) Cryptocoryne Pygmy chain swords jungle vals (languishing) moneywort java fern I think I have it all covered. So what do you think? Would you try it?
