So I have a 10 gallon, 80 degree temp, filtered with one betta. I've noticed every few days the water level gets low enough that I need to add about 1/2 gallon of water or the filter gets too strong for my girl (Yes, I need a filter sponge. Going to get one tomorrow)
So I add roughly 1-2 gallons per week, depending on evaporation.
The tank is clean, never cloudy and seems alright..
I was wondering if the evaporation and addition of 1-2 gallons per week is enough of a "water change" for this size tank.
I'm 23 week pregnant right now and can't do 100% water changes because I can't lift the tank anymore. I can do 50% if need be, but so far I've noticed my fish seems better off with additions of small portions of water as opposed to super changes every week/every other week. When I used to do that, she'd be a stressed out fish for days. Now she almost seems to enjoy the new water. She'll swim to the top and swim around as I add the water.
I will be adding a couple more betta girls soon.. Should I increase water changes when I do that?
I feel like I'm asking silly questions, but I adore this fish and would hate to cause her any issues. She's colored up soooo well lately and is very active, has an awesome personality shining through.. All that fun stuff
