well u won't be able to moderate your chemicals properly without the API tests. it is worth the 30bucks. if u want to lower the ph and alkalinity, try using peat moss. u can find some made for canister fillters and put it into a nylon sock and have the sock hiden in the corner of the tank or inside the filter. u could also use natural driftwood to give the tank a more natural look while keeping the chemicals right at the same time.

I'm so sorry I haven't been on the forum in so long! Don't worry, I haven't forgotten this lovely website! I moved to a different county back in May 2011 and started high school in a totally different school district. So I'm still adjusting and studying hard, and don't presently have any aquariums. But once I do, I'll be right back on this forum!
