Are any adjustments needed with how much peat and how much Diamond Black to add when used together in the same substrate? Or can you add the same amounts that would be used when using only one? I am leaning toward 7 - 8 tbsp. of Diamond Black with 3 - 4 handfuls of peat under Eco-Complete in a new 50 gal. tank.

I set up two 10s with this combination over the weekend. I used about 6 oz. of each, quite a lot. Don't have any idea how well it will do. The lignite thing is fairly new, the only person I know who has done it to date is John Wheeler and he doesn't post in this forum.

I'll bite, what are 'Black Diamond', 'Leonardite', and 'lignite'? Please include with your answers a 2 paragraph suport manual describing why you would put them in an aquarium and what benefits you expect to see. I expect all chemical equations to balance and or biological processes mentioned to include alternate senarios including the no action senario. :wink:

Seriously, whatcha talking about?

Diamond Black, leonardite and lignite are similar. See:

I'm planning on using Peat and Diamond Black as organic substrate additives in conjunction with mulm. The exact amounts are not yet defined, but they will go under Eco-Complete topped with Onyx Sand as Eco-Complete seems to be on the light (weight) side.

Ok, now that I know what you are doing I'm gonna go stick my head in the sand and pray that it all goes well for you. As an aside, do you already have planted tanks, and practice at battling algae?

aquaverde 03-16-2004 02:25 PM

That's all the encouragement I need, Sean. I put half a dozen Jobe's sticks in there as well. What do you think, urea in the water column and I'll be good to go?

/Disclaimer: Do NOT do this at home.

Oh, BTW, an extra added benefit- the water is turning sort of a nice shade of brown. Looks like I won't be needing that blackwater extract after all!
:D :) :? :shock:

Yes, I have had planted tanks for awhile. Have battled algae, mostly successfully, for over 25 years. Using organics (i.e., peat, mulm, soil - although I'm not partial to the potential mess with soil) in the substrate has not proved to be a cause for algae outbreaks. Jobes sticks have however, when disturbed. I would only use Seachem Flourish Tabs, if anything. With a sufficient topping to the peat - 3+" - the water did not noticably discolor.

That must be the difference.

The first tank I did was an existing setup. I couldn't get it really well-drained, so, as I mixed things and built the top layer, stuff tended to migrate upward, with the cap being about 2". The second setup was new, and I made it with almost 3-1/2" cap over the enriched part. No real discoloration in that second tank.

I'm glad to hear its an experienced person doing this, at least if it is a problem you'll fix it and not clog up the Algae forum. :wink: Keep us posted on your success.

I might use some when setting up my tank with Vladimir Simoes method...I might try bat gauno mixed with castings, that should be a potent additive, but with the help of the lignite it should keep it from leaching into the water.

I had some worm castings, but chickened out on them.

Go for it, how bad could it get? :wink:

Raul-7 03-18-2004 07:49 AM

Remember to mix a 50:50 of sand:castings. Should I mix lignite into the castings/bat gauno or layer it ontop of it? Would using FoxFarm Planting Mix be a bad idea, it contains: composted forest humus, sphagnum peat moss, earthworm castings, vermiculture compost (bedding material and manure), sandy loam, fossilized bat guano, granite dust, Norwegian kelp meal, dolomite lime and oyster shell (for pH adjustment).

Bear in mind, whatever you do or choose to experiment with, leonardite is an organic additive. Think of it as a longer term peat. My thinking is to use it either with peat or instead of peat. It's in what amounts/proportions that I'll be tinkering with. :)

SCMurphy 03-19-2004 05:37 PM

Oh, I'll be standing way back over there, hoping nothing goes wrong for you. :proud:
