Appreciate your responses and I have had a look.
Godly3vil! OMG! I have seen that huge tank you have built! I am stuck with a little 350L and the wife will not allow bigger, but you have now inspired me to work on the boss lady in adding a biiig one.
Adrienne, would you be able to confirm whether your results achieved are with excel dosing or with the help of a CO2 pressurised system?
I have found my glosso and pennywort did not do well in the heat at all. That was mainly due to a rookie error at the time, since then subsequent research have shown these do not like warm temperatures (28+) at all.
From what I can work out I face another issue and that is the need for a pressurised CO2 system, as opposed to the continued Excel and Flourish dosing. My results are very good and my plants are flourishing, but I want great results.
I am looking at adding a pressurised CO2 system with PH controller. Really love the results achieved with these, but I find the cost for this equipment a little unpallatable in NZ. It appears importing these is a challenge too...
