Although i have never had one personally, I thought that an arro could get up to 3-4' in length and be kinda aggressive. Seems every time I've seen one it had it's own tank that was much larger than a 125 gallons. Anyone out there have any first hand experience? As for your questions, the only one I can answer with any experience is about the pool filter sand. When I had my 75 gallon I used it with just some root tabs every few months and it worked great. I'm sure there are some other things that may be helpful as well, but that's all i used. Good luck with the new tank!
