shaywood Posted August 15, 2008 Share Posted August 15, 2008 Hope you can help. My KH is 12.5 (steadily going up from 10) and my PH is at 7.7 (measured in afternoon) - down slightly from 7.9. What can I do to get these back in balance? My Ca is at 480 with a reactor(effulent at PH of 6.4) and I Kalkwasser nighly for my top off. Mag is at 1350.

Smann Posted August 17, 2008 Share Posted August 17, 2008 sounds like you are running your reactor a bit high. On mine the instructions say the effulent should not be below 6.8 and you should monitor your PH to make sure it doesnt fall. I would slow the bubble count down and reduce the time you run it until things balance out, also your alk should be between 7-12 12 being the the max. If you adjust the bubble count you can recheck the effulent in an hour or so and it will change try for 6.8 and the alk should be 15-20(effulent) I only run mine during the day with my light cycle then adjust the time to maintain alk around 8-9 Quote Link to comment Share on other sites More sharing options...
Smann Posted August 17, 2008 Share Posted August 17, 2008 OOPs correction! havent read my instructions for a long time, it says start the reactor at 7.0 then slowly reduce the ph until you can maintain 6.5, but monitor the tank ph and if it begins to drop cut back on the C02. I have a second chamber so mine runs about 7.0 with the same results Quote Link to comment Share on other sites More sharing options...
shaywood Posted August 17, 2008 Author Share Posted August 17, 2008 Thanks. I've run it as low at 6.3, but have adjusted it up to 6.7. Quote Link to comment Share on other sites More sharing options...
