Yep, perhaps one of the nicer commercial brand/reasonable. I rarely support commercial brands however, because......they tend to be water, with a little tiny amount of fertilizer added.

Some folks get them, then reuse the bottle thereafter, same for ADA(pfertz are much cheaper).

KNO3, KH2PO4, GH booster, trace mixes, are very cheap dry. Unbeatably cheap. You also do not pay for shipping water, more plastic etc.

For some, the argument is that they do not wanna mess with KNO3 etc, scared of chemistry, claim it's harder, just wanna add a couple of 3 things and be done with it.

Poor observation, care and trying to get around the basics is questionable at best I think. Some chem is good and it can save you a lot of $ to learn a few simple things.

Even there, a dosing calculator makes quick work of the chem. So there's really not much argument other than hobbyists newbie ignorance. Sorry, I do have a tough time supporting that part.

i understand the folks that use premixed ferts to be ones that dont want to own the responsibilty. if the plants dont grow,(or algae explosion in the most cases) they will complain at the LFS and be persuaded that they need another premixed bottle of magic to solve their problem, normally this ends up with dis-illusionment and the LFS suppling endless variety of plants in plastic form.
not allowing the responsibilty to lay in the hands of the assistant at the shop that has never seen the tank and hasnt even asked what water parameters the tap water has, is the first step to take if anybody wants to have a well planted aquarium.

I have already bought dry fert from plantfertilizer.com and that is the route I am going with. I was just curious about the company. Mixing the dry with RO is easy and I have unlimited RO at the pharmacy. The calculator makes mixing even easier, pretty much a no brainer and a huge money saver. I however, have been reading that the Dry Trace mix is not something you can keep "it goes bad". I am not sure if this is true or not and that is why I was inquiring about the pfertz company and whether I should buy the Trace from them.


Thanks

I add about 10 mls Excel/glutaraldehyde for every 500mls of CMS+B.
This prevent any bacteria. Or you can also use 2-3mls of HCL at 9M.

Add these first to mix and dilute, then, add the CMS+B.

If the tap has higher KH, add some DTPH chelated Fe (add say 1-2 tsp per 1 liter of CMS).

I think many commercial companies(I am not sure about the one's listed here) that know of CMS and other cheap dry fert mixes, try everything they can to sway you, telling folks how they rot etc.

Well, anyone can add Excel/pool acid etc as long as they are careful and reasonable with it.

Brand name liquid doesn't ‘rot’ because there is preservative added.

I however, have been reading that the Dry Trace mix is not something you can keep "it goes bad".
If “going bad” means dry traces powder gets clumped by humidity. Is it worse than
traces mix suspending in the water, in the bottle? I don't think so. The clumped powder
is not that wet.
