Totally understand^^.
Good, I don't seem crazy then. I get the feeling that most think I am crazy because as I researched these products (probably more than most) before buying them all I did was confuse myself more and more from the contradictions. It also seems there are a lot of people saying lots of different things when it comes from dosing and if you compare all the low end guestimates to all the high end guestimates there's a HUGE difference between them.
and probably part of the reason I always base dosing on water change volume and not tank volume. If I know it's not in there in the first place, what's the point of removing it, especially if your water supply is good, which I'm lucky in that aspect. I think that's a marketing strategy myself. Kinda like when the manufacturers tells you to replace your bio every 6 months......
Yeah, I get that it's probably marketing and I also understand that more isn't really harmful to the fish but too much of anything isn't good. Not even good things. I also wonder how this assimilates over time. Does the unused portion convert to a gas and evaporate or what? If not, you will eventually have a buildup of.... something. I just don't know what that something is. Much like salts, if you measure for the amount of all the water each time you do a water change you will eventually build up harmful levels. I'm not saying that Prime/Safe is this way because I don't know enough about what it converts to during it's process. All I know according to Seachem is that it 'converts chlorine into something that fish can safely process' which doesn't get too specific. I would imagine there are some proprietary blends and giving too much detail away might give the recipe away to a competitor or something. I don't know. I would just like to have exact measurements preferably from Seachem and then I wouldn't care about these other details. But w/o knowing exactly what it does and what the results are of unused portions I don't feel comfortable guessing at dosage of chemicals.
My wife has a kitchen set that go down to 1/4 tsp. You could measure half of that. Pretty sure she got hers at Target
I'll check into that. Thanks for the tip.
