Marine1 Posted October 9, 2008 Share Posted October 9, 2008 I was wondering if someone can give me a list or a good source that gives ideal reef aquariums H2O perams; such as calcum, kH, pH, etc. Thanks in advance. Link to comment
Sergeant-G Posted October 9, 2008 Share Posted October 9, 2008 Ok lets see if I can answer this one for ya. PH 8.0-8.4 Nitrates 0 Nitrites 0 Ammonia 0 Phosphates 0 Calcium 400-450 Alk 2.5-3.5 meq/l or DKH 7-10 I pulled some of these levels from a book I have called The Marine Reef aquarium Handbook written by Dr. Robert J Goldstein. I hope this helps Also try using the search function here, on Google and other sites you never know what you will find. Casey Link to comment
vangvace Posted October 9, 2008 Share Posted October 9, 2008 Table 1. Parameters critical to control in reef aquaria. Parameter: Reef Aquaria Recommendation: Calcium 380-450 ppm Alkalinity 2.5-4 meq/L 7-11 dKH 125-200 ppm CaCO3 equivalents Salinity 35 ppt sg = 1.026 Temperature 76-83° F pH 7.8-8.5 OK 8.1-8.3 is better Magnesium 1250-1350 ppm Phosphate < 0.03 ppm Ammonia <0.1 ppm Table 2. Other parameters in reef aquaria. Parameter: Reef Aquaria Recommendation: Silica < 2 ppm, much lower if diatoms are a problem Iodine Control not recommended Nitrate < 0.2 ppm Nitrite < 0.2 ppm typically Strontium 5-15 ppm ORP Control not recommended Boron < 10 ppm Iron Below Kit Detection Limits (additions OK) -RH-F Link to comment

What should carbonate be. I have a reading of 143.2 is that good/bad? Link to comment
Sctn4Elk Posted October 9, 2008 Share Posted October 9, 2008 Those are definitely the tolerances, but as for IDEAL, I think that is subjective...using the above guidelines, I shoot for and maintain these: Calcium 450 Alkalinity 10 dKh SG 1.025 Temperature 77° F PH 8.3 Magnesium 1300 Phosphate 0 Ammonia 0 Nitrate 0 Nitrite 0 Strontium 10 I test weekly and use water changes and dosing to maintain these values...

xenon Posted October 9, 2008 Share Posted October 9, 2008 I try to maintain the following levels. Calcium 440 Alkalinity 11 dKh SG 1.026 Temperature 80° F PH 8.2 Magnesium 1350 Phosphate 0 Ammonia 0 Nitrate 0 Nitrite 0 Link to comment
juanjo Posted October 9, 2008 Share Posted October 9, 2008 Hi guys, Isn't alkalinity 10/11 a bit high? I thought it was better to keep it in the 8/9 zone... Link to comment
vangvace Posted October 9, 2008 Share Posted October 9, 2008 Hi guys, Isn't alkalinity 10/11 a bit high? I thought it was better to keep it in the 8/9 zone... it depends on what you're keeping, personal preference, and Alk/Ca balance. Link to comment
xenon Posted October 9, 2008 Share Posted October 9, 2008 Hi guys, Isn't alkalinity 10/11 a bit high? I thought it was better to keep it in the 8/9 zone... higher alk = faster growth and it helps to keep my ph higher. Link to comment
adicus Posted October 11, 2008 Share Posted October 11, 2008 Interesting that no one mentioned Iodine - which is important for coloring of corals and necessary for molting of some CUC. The proper level of I2 is 0.06 ppm Link to comment

The proper level of I2 is 0.06 ppm Too easy to nuke your tank with iodine. x50 in a nano. Take into account that test kits don't cover the three different forms of iodine in reef tanks... see where I'm going here? Link to comment
