:help: :help: ok i get ready to clean my tanks get everything set up ...get out the python gte the gravel vacumed get all the decorations rinsed and change one filter ...just like i always do...and then i start refilling and all is going well...then the water gets this funny bubbling stuff all through out it...i cant get it to settle it looks like i am still adding water theres a film on the water and the only thing i added was the dechlorinater..the same way i always do...so before adding fish i changed 75 % of the water again it still iss the same so I am adding water that was previously in the tank, i use the old tank water for housing the fish until the cleaning is complete...and that seemed to have helped a little but i need to get the fish back in there...water params are nitrates are according to the all in one strip...20ppm nitritesare 0 hardness is moderate ph is 7.2,which is what this tank reads consistantly as well...so what is whith the stupid bubbles and film on the water? :hang: :hang: on a limb here but we just had a huge set of thunderstorms ...could tis be the problem?
