mg0465a Posted February 23, 2010 Share Posted February 23, 2010 ive noticed the last 10 days the ph has gone down in my tank from 8.0 to 7.4 or 7.5... is this dangerously low? waht can i do to raise it? Link to comment
cruiZe Posted February 23, 2010 Share Posted February 23, 2010 hmmm, how old is your tank ? any type of fuge, or reverse lit area? the 24/7 lit fuge really helped stabilize my pH. Link to comment
RyanR1212 Posted February 23, 2010 Share Posted February 23, 2010 waterchange.. something weird is obvi happening in the water to change it that fast... Link to comment
mg0465a Posted February 23, 2010 Author Share Posted February 23, 2010 my fault.. just checked.. its 7.65... but thats still kinda low right? i just did a water change a few minutes ago.. hmmm, how old is your tank ? any type of fuge, or reverse lit area? the 24/7 lit fuge really helped stabilize my pH. the tank is 3 months old... in my signature u can see all that i have Link to comment
cptbjorn Posted February 23, 2010 Share Posted February 23, 2010 Has the weather been cold and do you have gas heat? More gas heat = higher CO2 levels = lower pH. You could run your skimmer air intake outside somehow to raise pH if you have elevated CO2 inside. Link to comment
mg0465a Posted February 23, 2010 Author Share Posted February 23, 2010 the temp has been a little cooler.. like 75.8-77 in the tank... Link to comment
Mr. Fosi Posted February 23, 2010 Share Posted February 23, 2010 Have you tested your alkalinity? Link to comment
lakshwadeep Posted February 23, 2010 Share Posted February 23, 2010 What test kit brand are you using? also: http://reefkeeping.com/issues/2004-09/rhf/index.php Link to comment
reefer916 Posted February 24, 2010 Share Posted February 24, 2010 What kind of salt are you using? Also, that's a pretty significant drop. Look into a better test kit or bring a sample of water to a trusted LFS. You could always add Ph buffer, but you need to find out what the reason is for the sharp drop. Have you started dosing anything? What are the rest of your water specs? Link to comment
bird Posted February 27, 2010 Share Posted February 27, 2010 Mine kept dropping too, but it was the ph probe needed recalibrating so I read some articles on ph and reef keeping. They pretty much all said that variations in ph happen quite a bit in home reef tanks and as long as calcium, alk and mag were kept within parameters that ph readings were not something to worry about. I unhooked my ph probe over a month ago and have yet to test the ph. And the results? Less worry, cost (less spent on all the buffers and such) and corals/fish are all doing fine. note:calcium, alk and mag must be stable along with proper nutrient export/maintenance procedures I am sure.
