Of course and you can say similar about calcium and anything else you might put in your tank even commercially aquarium products can contain "other things" that might not be safe long term.

Since calcium is a mineral yes, there can be naturally occurring contaminates. But to my knowledge there is no need to add a stabilizer to calcium. Since h2o2 rapidly breaks down they have to add a stabilizer to prevent that.

Not talking about a stabilizer in calcium but other potential contaminants/ undesirable elements. I am well aware there is no need for stabilizers in calcium, I have been using both calcium hydroxide and Chloride for over 35 years and always buy the high grade not tech grades.

consider this costly acrylic tube tank. One single scratch would be so annoying I wouldn’t want to own it, pristine is best. When dosing ferts and bright light we know green calcareous macro algae will dot the surface and set in, opaquing the top half of the tank if left unchecked within two weeks


the hobby only offers scraping options, there’s no other way to deal with it


but 3% is magical: no matter how hazy I let it build, a simple drain water/catch in brute, expose algae walls, lightly wet with perx from a wash rag and let sit in the air five mins, refill, never scrape. Within 48 hours the scum is killed, sloughs off, and total clarity resumes am talking clarity like day one. No matter how bad I put it off


nothing can beat that method for scratch prevention, in fw planted setups. I adjusted the lighting levels down so only the top 1/4 gets strength and I simply don’t have to clean down low. Peroxide is 100% the reason this tank is scratchless going on three years, not once single scratch at all.

Interesting, I wish I knew that in my FW days when it took a lot of elbow grease and patience to clean the sides with super soft poly. I'll make sure to share with my freshwater friends.
