I have two different root tabs, API Root Tabs and Seachem Flourish Tabs.
IMO, I overpayed for the API Root Tabs at a
LFS ($11.99 for 10 tabs). I was able to buy the Seachem Flourish Tabs at PetSmart at $8.99 for 10.
Has anyone had better luck with one over the other? Seachem suggests you can wait 3 months to replace the tab, while API states that you should replace theirs monthly. The size of the tabs from both would suggest to me that I could follow their recommendations.
