Kinda smoke in
the water, but since I like KMnO4 I’ll go with Smoke On the Water
A word or two about coagulants/flocculants. A while back, a question about haze in the aquarium came up. Of course the easy answer is shouted down.
While the words coagulant and flocculent are often used interchangeably, they actually have different meanings and I tend to say flocculent when I mean coagulant, my apologies
, I will try to get it right from here on…
In this thread, I am referring to aluminum or iron metal salt coagulants to form floc to remove colloidal particulates from the water column by sedimentation or mechanical filtration. Clay based flocculants with a possible mention of possible algae fighting.
Then of course, my favorite, definitely neither coagulant nor flocculent, but a favorite of mine, and a best-selling aquarium water clarifier of course with an unnamed ingredient that is okay until I post, suggesting the use of the ingredient, by name.
I get that the retailers and manufacturers know the idea of neutralizing colloidal material so they stick together requires a level of thought.
It is therefore; easy to develop dogma
asserting that since colloidal particles have a negative charge and since fish gills, have a negative charge any attempt to neutralize colloidal particles must damage the fish gills.
Gurus and cut-and-paste-types will repeat the dogma that only expensive devices can safely clear the haze.
The limiting factor in most coagulants is pH change, beyond pH change, too much coagulant could form gels that could clog gills, but by then the pH change would do the damage.
Worst of all, like me these methods are cheap and easy and as long as you pay attention, safe.
As a bonus to those interested, I will provide a sophisticated
approach utilizing a (common) hydrated metal and the mystery ingredient
