Re: [APD] Flourish Excel killing my shrimp and snails?
I had this experience when I first started using excel. What I found was to
start out instead of a large initial dose, to do smaller doses (I did 1/4
recommended dose) for a few days until they (snails & cherry red shrimp)
became acclimated to having excel added. Now I am able to dose the full
daily dose w/o causing any trouble. Hope this helps.

Subject: [APD] Flourish Excel killing my shrimp and snails?
I have kept planted tanks for years, mostly large tanks (55gal, 65 gal, 180
gal), high light and have always used pressurized C02 with all the bells and
Recently, I set up a 2.5 gallon metal framed tank and started using Flourish
Excel. I moved the Flourite, Onyx, driftwood, plants, fish, shrimp, and
snails from my existing 180 into this tank. They were all acclimated before
being placed into the water. The tank is lit by a 13 watt CF light inside a
I am good friends Tom Barr (who will probably see this post and wonder why I
am seeking advice since he has already given me his). His recommendation
for my size tank was 1ml per day, or every other day, which I followed.
My problem is, soon after moving everything into this tank, the shrimp began
acting erradic, and the snails all layed on the bottom. Within a few hours,
all the shrimp were dead, as were the snails. I have tried acclimating more
shrimp and snails from my 180 to the 2.5, but the shrimp die within hours,
and the snails are not too far behind. The fish seem to hide all day in the
thick growth, and I rarely see them.
I conducted a large water change this morning, and since that time, without
adding any Flourish Excel, the fish have become more active and are swimming
about. I did add all my other ferts and traces, so I feel confident they
are not causing my fish any harm.
Am I overdosing the Flourish and causing shrimp and snails to die because of
it? I assume whatever is wrong is related only to them, since both the
shrimp and snails have shells.
If I am overdosing, then does anyone have any idea as to what should be the
correct dosage given my high light and small size tank?
I also wonder if the metal tank is somehow causing me any problems reacting
with the Flourish Excel. I found the tank in a pet store I worked in during
my college years in the early 90's. I re-sealed it with aquarium sealant,
and used it for years as a beta tank, a breeding tank, and for guppies. I
never had any fish act like I had thrown them into bleach like my fish,
shrimp, and snails are acting now.
Plants are also growing slowly for such a high light tank. I trimmed the
top off a Bacopa four weeks ago, and just noticed yesterday that a new bud
has formed where I made the cut. In my high light, C02 injected tanks, this
would have happened in 3 or 4 days.
I've searched the archives for any other posts, and while I did find some, I
didn't see any replies that might shed some light on my situation.
I have also written Seachem for their advice.
Thanks for any help.
Don't be angry with my now Tom! ;^)
