Oh, then you are forgiven
The Seachem root tabs are usually found in most LFSs and big box stores. Expensive. An alternative is osmocote+ fertilizer in the clear gelcaps (aka Mebbid's root tabs). There are several folks on here who make their own and sell/trade/RAOK them. I just started using them a few weeks ago. Starting to see new leaves on my crypts in my low light tank. I also put them in my high light tank but hard to say if it has had any effect. Everything, including algae, grow in there!
