Hi Charlie & Star... "Thank you, both soo..much for all your help, in this matter. I'm beginning to understand it, a lot better.
Okay, I just did the finger test and there are air bubbles forming on it, as soon as I put my finger in his tank
However, I did just change another thing in his tank--I always had the water, more or less cascading into the tank (at the water level, to the point you couldn't hear the water entering--I hope you both understand what I'm trying to explain???). I just took out about 4 to 5 cups of water, so that the water is now "falling" into his tank, I can hear it hitting. Do you think, this could have caused the problem as well, as the old air pump???
Also, I'm wondering IF the cucumber, zucchini, carrot, etc. (only one of these nightly), could be the culprit, as one or the other is in his tank for almost 12 hours--could this be causing excess algae??? Since I have been doing the 25 % or a bit more water changes since, last week (every 2 days), because of the antibiotic I'm treating him with... I have noticed that when I siphon his gravel, it's pulling up very cloudy debris, from the gravel, however only along the edges. Do you think this is excess algae? Are these things, in his tank too long??? If so, how long should they be kept in for or are allowed to be kept in for..???
I'm hoping you both know what I'm trying to explain...I'm trying my best, so you both can help me.
Also, when I do his water changes, I am very careful with the temp. and his PH level. Also, I fill it with a cup, one by one and I pour the water in, from about 2 inches away from the surface of the tank water. Is this correct...am I doing that okay???
He's gone through soo..much and I just feel horrible with what's going on...
Thank you both, once again... for all your help and also, for helping me to understand what exactly is going on.....
