hi im new to planted tanks and was just wondering about some fertilizer tips, like if you guys use liquid fertilizer or the aquarium substrate fertilizer and how you add the substrate fertilizer in with the substrate.
I use a combination of three things: Large, frequent water changes to maintain phosphate, sulfate and nitrate levels in the tank water.
I rotate three to four different liquids every few months. Living things will be healthier with a combination of different foods and liquids are very easy to dose.
And, after several years in the "water keeping" hobby, I've found that long term, there's no better fert than that provided by the fish. I just feed a balanced diet of mostly frozen foods.
The plants have never complained!
