Just ordered some O+ from Amazon. Just wanted to know if anyone has tried it and if it is the same formula as the old Osmocote Plus.

My bottle does not contain calcium phosphate. It's the Outdoor & Indoor one with the "No-Burn Pledge". Which one is yours?
Same labeling and name as yours but mine came in a bag. On the bag, it lists Calcium Phosphate but no specific Calcium content under analysis. Kind of weird because you'd think they'd put it on there. Pretty sure Calcium Phosphate should be providing calcium as well as phosphorus.

I remember before it was discontinued, it came in a bottle, but I don't remember if it listed calcium phosphate.

Some sellers still sell the discontinued formula with calcium. I bought the 2lb bottle and it didn't have calcium. Was yours the 8lb bag for $20?

Yeah Osmocote Plus has been back for a while now, Scott's sold the Osmocote Plus brand to a company in Israel who brought the newly named "outdoor & indoor" to the U.S. market. As stated, the new Osmocote Plus Ouutdoor & Indoor does not contain calcium, and they used P2O5 as the source for phosphates.

Same quality and chemicals for the most part? Or did they mess it up and rely on the name..

Yeah every thing is essentially the same; Same materials, fertilizer compounds, and same ingredients in the time release gel-coat; It's just another company now owns the rights to the Osmocote Plus brand is all...

My thoughts are Scott's made a bad move when they decided to go with 50lb bags, and ditch the smaller quantity package's... Was a really bad move, but thankfully the company who bought the Osmocote Plus brand name was smart enough to realize the mistake Scott's made and started selling the smaller packaging quantities again.

Wait, why does it say Calcium Phosphate then, if there's no calcium? Seems like some people are saying its exactly the same but others are saying there's no calcium
You might have bought the discontinued supply, which Amazon actually sells. I just checked and the discontinued 1.25lb is being sold alongside the new O+ without Ca.

What you picked up is an old Osmocote Plus made by the original Scott's company, Scott's would use calcium phosphate as a source for phosphates. This is why you are seeing it, the new Osmocote Plus made by the new company has 0 calcium in it.

So far the differences pointed out are no Ca and P2O5 as the source for phosphates. How about the source of N? I saw the new product at the store and I had to do a double take since its was pink and not orange like the original one (which I always keep an eye on), attached is a pic that shows what's on the new stuff. Can anyone compare it with what's on the old stuff?

Is the new product FISH SAFE?

BTW, I posted a link to a rebate to make this Free on another thread.

I am sort of new to planted aquariums, but I have used O+ many many times as I was a for years...in this application is it used as substrate enhancer, like root zone tabs only with more blanket coverage?

Yeah Osmocote Plus is used for root tabs, or ice tabs; Either way Osmocote Plus is awesome for heavy root feeding plants like swords, crypts, etc....

Awesome, that's good to know, it's probably good for more inert substrates, because you can get it mixed in thoroughly.

I bought the O+ from wally world and didn't find out until recently that the formula has changed. While looking for more info on O+, I ended up on a Hydroponics forum that went into depth on the change of the new O+ and they don't seem t like the new stuff. I also read that Dynamite Select is very similar but missing Zinc.

Anyway the good news is that the original O+ is available in some areas. I have found it at Menards for $8 on clearance for 4.5lbs. but I didn't find t in the aisles. So I bought it online and sure enough they sent me an e-mail telling me it was ready for pick up. The bottles were SUPER dusty but they were the original formula. Just go to the Menards web site and put in the product SKU 2639270 . If you don't find it in your nearest store there is an option to search nearby stores. Good luck!
