Fertilizing A Tank

[MrNiceGuy]

i did some research after months of my plants not thriving and found out that i should use some fertilizer. all my plants are generally low-maintenance from what ive read. wisteria, swords, stuff like that. is fertilizer available at pet store chains like petsmart or is it somethin ill have to buy online? and how should i apply it? i'd rather use liquid if thats possible. thanks.

you should be able to get ferts in most fish shops.
look at tpn and tpn+ or similar
the + version contains nitrates and phosphates as well as the micros and K. so this may not be needed if the tank is heavily stocked with fish
add as directed on the bottle.
