i also have bioballs, bamboo and capyrus, so the tank has stayed cycled throughout the time since i set it up a while ago. thanks though, ill get back to you with the levels when i get a chance.
If you remove fish from the tank for any period of time ( which you already admitted to doing), the bacterium from the cycle can die off from lack off food (fish waste).
do NOT add CO2 when you already have fish that cannot breathe too well.
the reason we are asking for specific numbers for your tests are because different sets of numbers tell us different things. saying "I tested my number are fine" does NOT answer the questions we asked!
PH
Hardness
Ammonia
Nitrates
Nitrite
Give me numbers. I think you are just using the cheap-o testing strips and don't have a real testing kit.
I understand you worked at a pet store. Not all pet stores are as knowledgeable as they think. You cannot be taught something the teacher does not know. Its like, who do you ask about star wars movies- the kid who stocks them on the shelf at toys r us, or the nerd that is busy buying the darth vader with the vinyl cape and green lightsaber off ebay?
We are the fish nerds. Trust the nerds. Embrace the nerds.
On the MTS thing, it was actually a VERY common phrase in signatures here a few years ago when there were thousands of constant users. No one is making fun of MS, or any other disorder. I used to list MTS in my sig too, when I had a few hundred tanks.
