Timer is essential for consistency!
Liquid Fertilizer: Dose weekly (Seachem Flourish, Easy Green)
Root Tabs: For heavy root feeders (Swords, Crypts) — insert near plant base every 3 months
Gravel works for most beginner plants!
Sand works too
Aquasoils: Optional upgrade for advanced plant growth
Tip: Anubias and Java Fern attach to hardscape, so substrate doesn't matter!
Not needed for these beginner plants! CO2 systems are advanced and expensive.
Liquid carbon (e.g., Seachem Excel) is optional and helps some plants grow faster, but not required.
