IMHO, RO water isn't of much value for planted tanks, UNLESS you have local conditions that would justify it such as abnormally high nitrates, phosphates, perhaps even high levels of chlorine / chloramine, otherwise you're paying good money to remove things your plants will use most likely and then spending even more to put it back in. But as I stated, that's just an opinion. -----Original Message----- From: aga-member-bounces@thekrib.com [mailto:aga-member-bounces@thekrib.com]On Behalf Of Nickeydundee@aol.com Sent: Thursday, January 06, 2005 6:27 PM To: aga-member@thekrib.com Subject: [AGA-Member] RO water Hello Fellow Growers, I am using RO water for my planted discus tank. It is a 90 gallon tank and I do partial water changes of 30 gallons once a week. Before I add the water to the tank I have been adding TMG, Equillium, FE, K, N and CO2 injection. My tank has algae and isn't what I would call a work of art yet. Basically because I am still learning and I figured that I need to learn the basic of growing plants before calling the tank more than what it is. The more and more I have been reading I haven't come across anyone detailing the use of RO water in a planted aquarium. So, I ask why and is it worth the extra expense of using it. The benefit that I am getting from it is the that GH and KH are at my control and with discus that is a must but, I am still getting algae. Probably from still learning the ropes of adding the chemicals to the water. I just having found much about the use of RO water and balancing it with Liebig's law in mind. I have test kits and just about everything else (I guess having all the toys is the easy part) the every least my fish are doing great not the plants. If there is anyone out there that can help me piece all of it together I would be grateful for the help.
