It’s been months since I tested the water out in the unit cause honestly it’s fine 99% of the time. I’m still kind of concerned that the water is screwing with the growth of the plants, but maybe not. The water looks like it’s within acceptable levels for growth, it might just be that I don’t have enough fish in the tanks to generate the kind of nutrients the plants need. I’m thinking of bumping up to one more goldfish as well as adding in some variety for the food cause to date I’ve only fed them fish flakes. According to a couple different sources, including the Petsmart employee I spoke to the other day, i need to throw some veggies in there. Like a sliced strip of some vegetable that slips my mind right now. I’ll probably throw it in there tomorrow morning.
