I recommend you guys google for the thread discussing this last time.
It
has a very good explanation on why seachem excel *is* an algaecide.


I'd call it an algae inhibitor.
I tried it on Cladophora, it had no effect with a controlled tank full
of plants.
None, nada, zip.

The tank has good CO2, nutrient levels etc.
Cladophra was added and was allowed to grow well first prior.
Then it was added, 8 weeks later, ther BBA and Cladophora are still
there.

The Cladophora grows, slowly, the BBA not at all.
But neither dies.............

If we added Copper, they would certainly die.
In some tanks, like many snake oils, Excel will work, but unlike a
snake oil, Excel adds something that the plant needs: Carbon.

If you approach the issue from the plant's need, then these cases are
much easier to tease apart and show why some folks do not have issues
and others do.

If you have algae, you are likely, or have neglected the tank in some
way.
So you are starting with a problem already and the tank needs some
help.

I have gotten rid of every species of algae without using Excel or any
snake oil, pruning etc will go a long way.

But I will say try using Excel, it may help you, and if so, take a long
look at the CO2.

Take care of algae problems before they get so bad next time also, that
way they are much much easier to address.
