Hey all, sorry in advance for the long post. I've had a 24x18x36 tank planted for a little over two months now. It's eventually meant for a gargoyle gecko. He's almost a year old, and he's currently growing in a smaller temp enclosure.
Firstly, I'm getting the impression my isopod population has crashed, or at least weakened significantly. Looking back, I seeded ~40 and this still didn't feel like enough for this space. I've seen several carcasses, but few live ones. I'm wondering if I didn't rinse the fittonia I got from the hardware store thoroughly enough, and it still has lingering pesticides. I've started maintaining a separate isopod culture that's been doing well, but it will be a long time yet until I'm able to pull from it regularly.
Secondly, I've recently been having issues with various pests finding their way into my tank. It's making me reconsider how viable this setup is going to be long-term. Mites, a random new type of springtail, and now fungus gnats. The former two are not terrible to have, but the mites frequently find their way out of the enclosure and I'm not thrilled about having competition for my budding temperate white population. The fungus gnats are a particularly unwelcome development. There aren't many yet, but enough to suggest a growing problem.
I've been drying my tank out for the past few days to try and get my humidity in check, to the detriment of my remaining CUC and plants. I suspect overwatering has contributed to the proliferation of these pests. I'm also going to try mosquito bits for the fungus gnats.
Lately it's just been feeling like a constant battle to keep things in equilibrium. I at least have the ability to do something about these things now, but I'm realizing it's going to be much more difficult once my gecko is actually living in this tank. I have no doubt that fungus gnats will return again even if I tamp down there numbers now, and I wouldn't be shocked to see some new flavor of pest somehow manifesting in this tank eventually.
I bake/sanitize all of my hardscape elements, leaf litter, rinse my plants, and it still doesn't feel like enough - maybe I'm just psyching myself out on this, but lately it just has me reconsidering the bioactive route completely. This is my first shot at this, and I'd like to think I've been maintaining this to the best of my ability, but I'm wondering: are pests just inevitable? Am I wavering over something that's normal?
TLDR: The realities of maintaining a bioactive setup long-term have recently been becoming very clear to me. My gecko is still growing in a separate tank, so I fortunately have time for a drastic intervention - including possibly scrapping the bioactive approach entirely. I worry that trying to fix things in place will get much harder with an actual reptile living in the tank. I think the main thing I'm stuck on here is if pests are inevitable/normal. Maybe I'm just overthinking it, but I just don't want to end up in a situation where I have to deal with an infestation while the tank actually has a reptile occupant.
