So I've had great results using Osmocote Gel caps I bought from a dude on here. My Tiger Lotuses and Amazon Swords are really looking amazing and growing fast, despite only having moderate lighting and around 20-25 ppm co2.
My question is, how often should I replace the root tabs? Secondly, as the plants get bigger will they need more tabs/ more frequent replacements?
I just don't want to have them become deficient again...really looked terrible before I started with O+ tabs and only had plain laterite under the gravel.
