Lookin good Coltrain... thats a sign of great water
All the stem plants look healthy and the yellowing of the sword is normal on a new substrate. Some fert tabs in the substrate will take care of the sword and even benefit the stem plants as well. I like a rich substrate, after all they are plants...LOL
Other then that , I wouldnt be adding any ferts to that tank yet either, the micro's you have in the tap are doing great. Not all water is the same.
Gonna start dosing ferts soon and adding more fish.
Think of it this way, adding more fish is adding more ferts... ya gotta love free nitrates !!
Anyways...Dont make the common mistake of fertilizing the water column because you think you should
, start dosing the plants when they show you
that they should, otherwise that nasty stuff that begins with the letter "Algae
" pays us a visit.
Lookin good Coltrain, keep us posted !
