Glad to see you around as well. I think the PO4 reactor is a great start. I dont like to use too much at once though, a cup is plenty IMO and Id rather change it out twice as often than use twice as much. Remember that all the algae you remove manually is also removing PO4 and even if it grows back its still consuming more. Also do a seach on Kent Tech M magnesium, a lot of people swear by this stuff for Hair algae. Its not so much the mag but a bi-product from this specific brand apparently. I also love tuxedo urchins, best algae eater ive had. Hope this helps, good luck and let me know how it goes.
