Aquarium Advice FINatic
I don't know what my levels are, haven't tested for a week. I'm doing a water change today and cleaning up my plants. I will add more root tabs also. I have flourish root tabs and api leaf zone liquid plant food. How often should I dose the liquid and how much? 55 gal tank. Also, how often should I replenish the tabs? It said lasts for 3 months?
I can definitely help here as I've used the Flourish tabs before. I don't have the same swords as you but mine are super greedy and exhausted my tabs pretty quickly.
As Rivercats suggested trim all the dying leaves so the plant doesn't expend energy on them. Also try cutting the tabs into halves and fourths if possible. I was able to cover more area this way.
On my 55 I use 2 capfuls of Leaf Zone weekly. I have way more stem feeders than you and this regimen works for me. Leaf Zone directions say 5ml per 10 gallons. The cap holds 10ml so I add one capful after pwc and another the next day. Also look into dosing micros for your water column. Flourish Comprehensive will be perfect and lasts a good while. One 500 ml bottle has lasted me months easily. I use 2 capfuls weekly. You're also going to need a source of carbon. Excel or Metricide. I'm using Excel but plan on switching to Metricide as it's more cost effective. I use one capful daily.
I also have a thread on DYI root tabs. You might want to look into that to save a few bucks. I liked the Flourish tabs but as I said they exhausted much too quickly for me and are kinda of expensive.
With this regimen my Anubias Nana petite has been thriving. As are quite a few of my plants. I have some that aren't but I'll need to upgrade lighting and fert dosing methods to get better results from them. Hope this helps!
