[APD] Caution with lead weights (was Re: Keeping Plants Rooted with MTS)

[Wright Huntley <whuntley at verizon_net>]

I have accidentally killed whole tanks of fish with lead weights, so I 
urge caution with their use.

If the tank goes acidic, and many softer-water tanks do (particularly 
with added CO2), the lead dissolves or is etched and becomes very toxic 
in the water.

At that point, the fish may show severe neurological damage, and swim 
erratically. A quick water change and raising KH can potentially halt 
the process, but the damage to the fish is already done, and many will 
not survive.

As you may guess, I have been down on lead plant anchors since I killed 
off a whole strain of particularly nice killifish.
