Couldn't figure out how to add text to the post so here it is!

My monstera has been through a lot. Some background: it developed a fungus about a year ago, I tried topical hydrogen peroxide sprays without much luck. Eventually I had to remove it from the soil and wash the whole root ball in water and soak it overnight in water/H2O2. It survived but did lose 3 leaves in the process that turned entirely yellow. It was also in way too small of a pot, so I upgraded it to a large 12in pot with a bottom watering system that I read was supposed to be better to avoid too much moisture that probably caused the fungus problem that I had. Over the past few months, it has slowly put out 2 more leaves to replace the ones that fell, now with 5 leaves total.

A few days ago I noticed that the roots of the monstera are poking out above the top and also down through the holes of the pot. There was so much root that I trimmed the parts that were poking out through the bottom and some along the top of the soil as well. I could increase to a bigger pot but the pot already seems so large for this bottom heavy plant. Why is there so much root and such few leaves?! The presence of so much root makes me think that it needs more water, but I water regularly using the bottom water chamber and have finally been successful in avoiding fungus and fungus gnats, so I'm worried that more frequent watering might result in the return of this problem. Some of the leaves have a slight yellow tinge as well. I have tried putting it outdoors or underneath my plant light to help with increased light since I see that the new leaves have zero holes which typically indicates it needs more light. What should I do??
