I have always had readings of 0 in both ammonia and nitrites. It is been over a month and still the same readings. Why is this? and is my tank cycled yet? My fish load is not heavy and my filters are: 2 aquaclear 500's with double sponges and an eheim wet/dry.
Do you think it is better to double up on the sponges on my aquaclear filters, or use carbon and only 1 sponge? Which combo is best? I have heard carbon only eliminates odor
thanks for all of the help guys. I wasn't planning on tearing down my tank but just wanted to know if it was ok to vacuum the gravel that I could reach. And I got my answer. Besides I have 2 aquaclear 500's with double sponges in each for my mech. filters. For those of you that change 30 to 50%...
My tank is 135g and has about 100lbs of lace rock in it. I plan on completly taking out the rocks and siphoning the gravel every 6 months or so. Right now I just clean the front of my gravel and where ever I can reach with the siphon every few weeks. Do any of you with large tanks completly...
I may want to switch from rock to sand substrate in the future but I have fish already in my tank. If I switch substrates, will this kill my fish. I am just concerned at the begining when I put the sand in. The sand will not settle right away and I am worried that my fish will be killed.
Every couple of months or so I notice a white filmy build up on the inside glass of my tank. What is the easiest way to clean this? And what might it be?
