I know I need to have bacteria forming in my tank before I start having my fish in my tank, but getting the bacteria to grow in my tank has been a real hassle. I tried getting a rock from my friends fish tank who has brackish water but it didn't work, and I bought biozyme, and started using up but all it did was raise my Ph level too high and nothing else happened. I heard Biosphere is really good but I haven't been able to find it in any of my local fish stores. I have no idea what else I should do, I thought about borrowing my friends filter and using that to help start it but his tank isn't in the best shape and I don't want to get my tank off to a bad start. I heard a lot of bacteria starters might take a month to see results, but at this point I've been trying for over a month, so I am willing to wait another month just to get my bacteria started. Also I am using sand instead of gravel, I hope thats not the reason why its so hard.
