It depends on your bio load and if you will have any other bio filtration. If this is going to be your only bio filter on the tank you'll need a good amount. I can't remember off the top of my head, there's a formula online that'll tell you how much k1 you need for the bio load you have. But tbh it doesn't have to be exact. A good measure is to buy some, in your case, a large bucket worth, and measure the nitrates. If there still high after the k1 has been established then you'll need more. Another factor is how much space you have? Ohh, and k3 is better suited to faster flow, as its larger and doesn't clog as easy.
It might benefit you to maybe Google it or go to the website.....
My experience says, and don't just rely on what I or anyone else sys, use more than recommended. For a 300 with only two rays....probably be fine with like 5gal...
Like was asked, is it going to be your only bio media? The real question shouldn't be how much...since you haven't researched it, the question should be, who has used it and to what effect? How do you like it? Is it better than..etc...most people on this site will not only give you an opinion, but given enough info on what exactly you invision, they will stop at nothing to reach a conclusion...bend over backward if need be.
A 300 gallon tank is decent size. Two rays, even large ones, won't be considered a heavy bio load....so, error on the side of caution and buy as much K1as recommended...then add say 10%...hopefully you have room under the tank in whatever you will be putting the fluidized bed in.....

ive researched it quite a bit but it is measured by how much food is fed... but given the fact each fish gives a different amount of waste i dont think the measurement would be accurate. Especially since stingrays and goldfish produce about 3-4x the amount of ammonia that community and cichlids would. As for the filtration question (i thought i answered this but i guess my phone never posted it), i have a single FX6 and a sump i will move to another tank. i plan on moving the current sump to a large cichlid tank. i feel that the rays should deserve a better filter (i like the rays better xD). i plan on making the sump that URUAJOEY did in his recent video. it is a glass sump with acrylic baffles, but with his video he didnt make it very clear how much media he said to use. i cant tell if he said 15 or 50 given either my poor hearing or my computer just sucks. i currently have about 2 cubic feet (about 55 liters) of the original K1 kaldness (the ones with only the cross in the middle). and i have another 2 cubic feet of the improved k1 kaldness (not the helix, but the ones with the pentagon in the middle). well actually they are knock offs but will work just as well i believe. and i plan to put more rays into the tank. possibly 4 maximum in the tank till i get a bigger one.
I believe you mean if the nitrates are non-existent then add more as K1 isn't going to lower them.
