Been in planted tanks (as we know it) for 23 years at least. And I'm still learning. There was a gap of a few years in between, but my current run with the current tank is about 10 years long.
I started with aquariums in my early teens, influenced by my dad. That's easily 40 over years ago. We had elodea and duckweed, but I don't think that really counts. Had other pets as well.
Stopped when school got too busy and my dad shifted to gardening.
Only got back into aquariums a few years after I started working and ended up in a company where my boss had a teef tank in his office and colleagues had a community tank with some plants. Got into some aquarium forums which turned out to be planted tank forums and that's where it all started (late 1990s). Got seduced into the hobby by Amano's photos!
Soon after, got married, got our own home and "poof" 4 tanks: 100cm planted tank, 100cm newt tank, 90cm Tanganyikan Lake tank and a 180cm (180G, 680L) Arowana planted tank.
Life happened, and those tanks were closed down 4 or 5 years later, which started the gap.
2013 New home, new tank: another 180G Arowana planted tank.
When it started...
Today (literally), 11 year old tank, 11 year old Red Arowana.
Still learning about algae and fertilisation. Now more about the nuances in those disciplines, and finding my own system and methods. The hobby also speaks to my love of learning, tech, fiddling and DIY, and strengths/joy in troubleshooting and problem-solving.
Going forward, I may upgrade to a slightly bigger tank for the big guy. Logistics and space are the main challenges for that. When that happens, I will be looking into an automated water change system. Would also love a second smaller tank so that I can keep other fishes.
