Woo!! Heater arrived and seems to be in perfect condition. Thankfully, even if it ends up malfunctioning somehow, I don't have any fish in the tank for it to kill, so I can safely monitor it until I am confident it's working properly.
Now I have this mangrove root sitting around... and I dunno what to do with it... goodness, I might just need to get another tank to put it in... -shifty eyes- I mean... no need to waste a perfectly good decoration, right? Am I right??
Okay, churn the sand every 8 weeks. But yeah, I'll probably do a bit of it each week when I do water changes. But at least it should be good while the tank is cycling and I'm not doing any water changes.
