I won't.
I still think over all, Excel is one of the better algcides out there for aquarium use.
Excel in ponds etc did very little, I think that ponds are just too dirty and filthy.
The Excel gets used up there.
Many pond plants are floaters anyway and BBA is not an issue there, mostly green algae.
So after doing a few simple test, you can tell pretty quick if the product works or not and would be suitable for general care.
The good news is that when some Company comes along in the future and you can see what the list of ingredients are, you will know it and what it does
under aquarium conditions to aquarium algal species.
So we know ahead of time if the claims will be baloney and they are trying to promote untested products in this specific case(but it has been tested with different results for pond use).
You need an alga in log phase blooming or some that's adult and been hanging on, and be sure it would not had died on it's own due to improved conditions.
Neither myself or others had any evident that algae did that, so we can suggest it did no harm.
It either works for
all cases, or it really does not work much at all
Excel etc, we can add and see in most cases see dying algae. Not much here at all.
However, we also know that this product is not harmful to critters and plants also.
Also good news, and we tried and tested under aquarium conditions. Some troll seemed to want to play Animal Right politics and hit emotional hot buttons rather than discuss the Facts but ............we often get at least one lazy clown for any new discussion when it comes to testing things, but that are plenty willing to spend lots of time whining. This is par for the course being on the web. Get use to it
Most algicides need to kill, harm the algae, simple as that, it either works, or it doesn't. And it needs to work in stable adult algae stage and when the algae is blooming. If not in most cases, then it's rather dubious(as most have been over the years other than copper, Peroxide spot treatments, Excel and some antibiotics for BGA)
I still think Water changes, UV, Micron filters, Blackouts, good stable CO2, reducing light, good dosing routines etc, will do a lot more.
As far as
chemical treatments to tanks with fish, shrimp, plants, Excel is about the best overall product.
