Title: Must have!!
Review: This is a must have for planted aquariums. I have a 45 gallon and used two bags of this as my top layer and I haven't had to use any supplements for my plants. As other people may have stated, you absolutely need to rinse this stuff before using it. Don't worry, you won't rinse away all the nutrients! I probably rinsed one bag about 15 times and my tank was still a little cloudy for at least 4 or 5 days. You can add finer gravel on top if you prefer.
