[GSAS-Member] Anyone successfully using "Seachem Excel" in their planted tanks?
I tried it for the first time yesterday.
Followed the directions for 'setting up the tank.' Tank had been set up for
about 6 weeks, had 6 Hyph. amandae and 6 N. marginatus pencilfish, plus the
rocking ancistrus and a few odd killies. 55 gallon tank, so I added 50 Ml of
this stuff after doing a 20% water change.
This Excel stuff is *bad news*.
Next day: All but 2 amandae dead (and one isn't looking good.) Lost 2
marginatus. Catfish and killies seem fine, killies are notoriously tough when
it comes to polluted environments.
Plants look the same.
Just did a big water change and added polyfilter to get that junk out. *Then*
(stupid me) I looked at the data sheet for this stuff.
It's an aldehyde (like in Form-aldehyde.) It's rated 1.5 on a 1-3 scale as a
toxic pollutant. It smells funny - now I know why I recognized the smell. It's
not formaldehyde, exactly, but it's an aldehyde that when in water releases
iron and carbon into the water (and will preserve speciments at a high enough
concentration.)
The stuff should have a skull and crossbones on the label.
So, does anyone actually use this garbage successfully? Anyone want a big
bottle of it before I bring it to toxic waste recycle?
Man, the stuff the tropical fish industry promulgates onto the unsuspecting
hobbyist... Just another reminder to not trust the tropical fish industry as
far as you can throw them.
