Ok, I've got a stupid question, my tank (5 gallon) has only been set up for about a week and a half.
0 Nitrites, about 15 Nitrates, 25 ppm hardness (very soft), 0 alkalinity, 6.8 ph (that is if my test strips are working, I'm having the pet store test a sample in a day or two just to make sure.) Don't know the ammonia level, stupid 5-in-1 strips don't test for that.
I have a betta and a bunch of plants in it, and I'm planning on getting some kuhli loaches.
Since I just had one die I'm kind of paranoid now and want things to be perfect to give the buggers a chance. My tank has medium sized, rounded gravel in it. Is that too big for the loaches, should I switch to sand?
I also have a castle and cave system for them to hide in besides the plants.
If I switch to sand what will that do to have far my tank has cycled? Am I going to be pushed back a week by it, or does it not make a difference?
