The situation...Been keeping planted tanks for some time with the use of nutrients/trace elements and good light with reasonable success. Recently I decided to try DIY Co2 on my 90ish gallon tank, knowing that it would have to be a pretty special unit if it was to supply a tank this big. So, off to the drawing board and; my attempt seems to have been successful.....I think! It comprises of two 3.5 litre pressure garden sprayers (You know the type that spray weed killer) that had nossels that accepted my tubing easily. This was then fed into an "inline" garden hose filter which is connected to a very compact 700lph pump. I just put some corse sponge in the filter and, after the initial observation of bubbles reaching the surface, connected some large clear hose to the other end to extend the contact time of the bubbles before leaving the "reactor". All good!
The problem....... I know that there is a direct relationship between Ph and Kh, so I buffered the water and waited for my Ph to drop to around 6.8 as it is at 7.8 at the moment (which is unusual in itself)......but nothing, not even a small move! It has been nearly four days bubbling very nicely at a huge rate and the Kh is at 6d but the Ph wont budge! Is this a direct relationship to the large volume of water and I am just being impatient? I have done every thing I can think of including sealing my trickle filter. Is there a problem I am missing or is it a matter of giving it more time?
