Thanks. >> Hi, Heather: Welcome to the mania. Your water parameters aren't totally hopeless. However, I recommend (you will find we all have our own theories about this stuff) that you treat it by using an RO or DI unit to reduce your GH, or buy a product by Mardel called Ta nk Soft. You can cut your hardness in half real easy with either of these approaches. I would also lose the plastic plants and include floating plants. 10% changes each week should be adequate unless you are heavily stocked. Just for the record, ramirezi aren't Apistos. A. agassizi and A. cacatuoides are good choices, and there are also a number of regularly available Apistos you should have no problem. Good luck Bob Dixon
