It's hard to tell at the moment. But within the next couple of weeks I should be able to tell you. To me my plants are already starting to look better. But I will feel more confident when I can see some growth.
Update on tanks: red tank FINALLY added a heater. So now working on getting him some type of cave for his home and some tank mates.
Blue tank added dwarf hairgrass and root tabs. Also a lovely little blue cave thing that my betta loves. He has been doing well with his two shrimp and two snail buddies. The two blue ramshorn snails every since I've added live plants are sooo much more active in the tank and no longer burrow into the sand!
