I did the same to poor
@Essjay when I joined! I'm not good at chemistry, and took me a while to wrap my head around pH, GH, KH etc, and she was super kind and patient trying to explain it to me! And demanding she help me with a shrimp crisis etc - I bet she started to dread finding all her notifications were me tagging her, asking her to explain cycling to me or someone else
We're really lucky with our mod group here. Nice folks who don't power trip or throw their weight around, but keep an eye and do their best to help when needed

Also just nice, genuinely kind and helpful folks, who will take a lot of time to help people who are willing to learn.
@Essjay , to be honest, I still haven't really got the hang of how pH, GH and KH interact...

I'm really a chemistry dunce!
@Matty24 - give yourself credit too! It's very clear how much work and effort you've poured into the tank. The tank and plants show it! Shows that you've been willing to learn and have put a lot into it! No tank is ever "finished". They're a constantly evolving thing when it's a personal tank you plan to keep and not an aquascaping contest or something. The contests are just a snapshot of how your tank is doing at that time. But there's always going to be something you want to change or improve! So don't wait until you think it's perfect, since it doesn't need to be, and then you'll never enter since there's always something you want to change at some point.
The contests are just a snapshot of how your tank is at this time, and right now, your tank absolutely deserves an entry into a TOTM contest!
