evil_elmo Posted December 28, 2005 Report Share Posted December 28, 2005 hi i just setup my pressurised Co2 yesterday and i noticed that my ph level drops, normaly my tank is about 6.5 but with the co2 it drops to 5.5 is that ok for my discus? since my co2 gets turned off at night the ph rises again but will drop when co2 gets turned on during the day i readed that discus dont like the ph changing alot, is this ok for them? Thanks Quote Link to comment Share on other sites More sharing options...
Luke* Posted December 28, 2005 Report Share Posted December 28, 2005 They can handle 5.5 but 6.0 is better. Constant fluctuations they don't like, it's like for us going from high humidity to low humidity all day...we'd get stressed and sick eventually too. In saying that small fluctuations are fine. Your pH shouldn't change much at night if you turn it off because the plants stop using the pH and you stop putting it in, if it is lowering during the day you're probably putting too much in. If you test the KH and pH you will can find a chart that will show you your CO2 concentration and what the ideal is. You can also add baking soda as a buffer (raises the pH and KH) so it isn't so susceptible to pH crashes and fluctuations. You'd have to experiment with the quantities, but when you do a water change obviously then add back in a small amount. For my 4-foot tank (300L) i'd do a 40% water change and add back in 2 teapsoons. Quote Link to comment Share on other sites More sharing options...

LYNDYLOO Posted December 29, 2005 Report Share Posted December 29, 2005 Hi Evil, Just remember, adjust these things slowly. I think the measurements are 1/2 teaspoons baking soda to every 100Ltrs. Lynda Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted January 2, 2006 Report Share Posted January 2, 2006 Hi I have 124 Tanks mostly big like 180 to 300 liters with average of about 250 L If Discus get dark coloured i take PH down to 4 and have had as low as 3.6 with no sign to distress..I have had blue diamonds so sick with bactera attack thay lay on bottom for 7 to 10 days before getting up again. Two weeks later still at low Ph and have recovered..Key is Bacteria at 4 Ph cannot muliply so antibodies in fish get on top..And win..But to changing Ph i also have gone from 6.5 to 4 in one hour and still no sign of stress.. But in saying this mostly not a good idea to allow changes to happen when gas turned off.Not every day.. I have been trying plants and most cannot live in 95% rain and touch of mains.. Plus higher temps..But just got some Amazon swords to try..Hoping will help with nitrates.. My newest invention is the adding of Enzymes to tanks ..Modified septic enzymes are now in general bulk supply { 25000 L } and i have had one New 270 L tank with stresszyme and enzymes and 11 adult Discus and two weeks later still not Nitrite. Looking when product is refinded will be marketing it under our New Zealand Discus Brand..Cheers Phill Collis Quote Link to comment Share on other sites More sharing options...
