I bought the wrong root tabs, I see now the package says "Pond Tablets", also the nutrients are much more concentrated. Any chance I can still use these or will it cause problems? The pond tablits say 10-12-8 while the flourish tabs say 0.28-0.17-0.16 maybe if I broke the pond tablets into 20 pieces (they are larger than flourish tabs) and used fewer of them im still good, or no? I just dont want to drive back into town to get another $7 pack of root tabs, plus I already opened them. and I was just thinking, these could be much more economical since there is probably 100 times more fretilizer in there.
