I don't think this is a issue just want to verify this. Just wondering if my tank will be going trough a cycling process. Its a 25 h with 2 hob filters. Its been setup for several years. I removed all the fish and put them in a different tank. I took about 1/4 of the gravel out (also rinsed it) and added 20lbs of the carib sea eco plant substrate then placed the rest of the gravel on top. Before I placed the added the caribsea and gravel back in I siphoned the gravel real good and removed about 1/2 the water and replaced it. Since it was a mess I cleaned one of the hobs and the filter pad and placed it back in. In the next day or 2 Im going to clean the other hob filter with a new filter pad. I've ordered 8 plants which will be here in a couple days. Was planning on adding a pair of rams the following day. Just wanted to verify that there should not be any cycling. I've not check for amonia or nitrites yet but plan to in a couple days. Thanks
