Well its just a little bit of research for that product to see if it does at least stop my algal bloom. Im not naive enough to think this will rid of it in my tank forever.
So why bother in the first place?
I think we all try stuff like this out of desperation when we start in the hobby.
But desperate folks are the target group they market these products to.
Copper works also and has been used to selectively kill algae and not plants for well over 50+ years. The herbicide simazime also is effective.
Still, do you see me, or most any one that's been around for awhile suggesting algicides? Very few, unless they sell it, ever suggest these things.
Ponder why that might be.
I've been down this path, have been tempted, and used these types of products
They never offered me any real help that say a blackout might, or a good CO2 level. The magic algicide in the bottle does not grow plants.
If not, do not add it.
Killing algae that is there is fairly easy and requires only some rather cheap things we all have available, eg H2O2 spot treatment, Excel etc.........Excel actually grows plants so it's an exception. Plants are not going anywhere/die etc nor is the algae going to be that much worse without these products either.
They cannot since these products kill algae and do not grow plants other than Excel, so they do not "help" plants. This is the issue, they do not target the root issue why you have algae issues in the first place. So they offer little more than a distraction and waste of $$ out of your wallet.
Some have suggested I'm not being open minded and that they have use, rubbish, I've messed with this stuff far longer than anyone on these forums.
I also know the mechanism of actions and physiology for the chemicals used, much like I know about aquatic herbicides from the academic side.
I do try to find ways to beat back algae and then help the plants get better, but the methods tend to be with things like light modification, blackouts, good post nutrients/CO2/light routines, good cleaning, current changes.
Basic horticulture focused on plants and aquarium keeping, not buying yet another miracle in the bottle for 9.99$. Will it get rid of the algae? Maybe. Maybe not. Will it help grow plants and solve the root, not likely. Do folks "in the know" suggest it? Nope. You might use it for a time, but I doubt you will thereafter.
"Why not? What do I have to lose?" that is the marketing and the niche they want to use to sell the product. So we see new ones come out year after year after year. Often with the same things added, just repackaged. Some have no basis at all, but most have copper (which is why they are green) or are triazine based.
