no, it is more the fact the debris gets stirred up in the water as i siphon the gravel and it makes it a bit murky (yellow-green). even after adding more water into it. so lots of particles float around in the water, and it takes a little before they settle back down and water becomes clear looking again. i have also seen more particles floating through the water when it is clear looking, lots less than when i first clean it and it gets stirred up. also when looking at the surface of the water from below, it seems there is like a weird mild grease-like looking film on the the surface of the water, i dunno if it is caused by the water conditioner, the fish, the food, or the algae, but i wondered if that is normal.
this reminds me, i think the power filter may be too strong for my betta, it constantly is grabbing food in the current and throwing it down to the floor or the tank or whipping it around to the far side only to have it get caught in the current again. even though the current mostly just affects the top of the tank, i still see my betta being weird and look like it is trying to swim against the current from time to time. as a result of this, a lot of the food ends up on the floor and not in the Steve's mouth.
it is a topfin power filter (the removable top says Topfin 10) and it looks like it has a thin white carbon filter thing which i assume is the one i replace monthly and then it has a green honeycomb looking thing in it too, i assume that one is left in the filter.
