substrate for amazon tank


A.PROPHECY

Recommended Posts

It is just peat and mud, leaves, silt, maybe some sand in the Amazon I believe. I use brightwater gravel it's called, small grade. It's pretty close to black, dark grey really. Or you could use a thin layer of black fine grade pool filter sand. HTH

i have sand in my slightly amazon themed tank. amazon substrates are pretty gunky i would imagine :lol: also depends on if your having bottom feeders, i find cories love sand alot more than they do gravel and its better for their barbells (as long as its not sharp sand), try and get gravel with nice edges if you have bottom feeders. sand doesnt get sucked up with water changes, the very fine silt does but you only have to hover above sand as the gunk cant get down lower so it makes maintenence a bit easier. of course you have to make sure it doesnt go anerobic as it compacts but thats easy enough to get rid of (i run a fork thru the sand once a week, staying away from plants and their roots)

Remember to think of the practical side too. If you're going to use sand you'll need under gravel heating to get a slow current flow otherwise the gravel will go rotten and kill the plant roots.

I've found the best stuff is a compromise between sand and gravel. I use a small graded stone of 1-4mm in size. It does not pack down and there is enough flow in the gravel to stop it rotting. The flow is not enough to leach out the fertiliser though.

I use an inert stone with no organics added. These will arrive all by themselves anyway from waste. I add fertiliser tablets to control whats going into the gravel. Before I had to move, my tank had been set up for eight years without having to rip up the gravel and start again.

id probably use that bright water gravel then. sand and plecos dont mix very well in my experience (with anything large that BN that is), they fluff it all up and if it gets into your filters impellors is can be nasty :lol:

im going to get some malaysian trumpet snails for my sandy tank, apparently theyre going to be my little sand airators :lol:

Well, if you're going to have large cichlids then kiss goodbye any idea of having plants.

There's two reasons:

1. You either have plants and do the job properly or it's a waste of time trying - the plants will just slowly die off.

2. Large cichlids will continually uproot almost any plant you try to grow.
