Hi All,
Both my tanks have what would be classed as low light which i cannot change unless the built in hood was taken off. Something i dont plan to do just yet.
I also added Pressurised CO2 to my main tank in the past however i found that due to my lack of light and choice of plants (java ferns, Crypts, vallis and hygro) nothing really changed other than the Hygro bolted towards the surface at what appeared to be a weaker appearance. Hence i removed the Co2 and made suttle changes to adding my Tropica Nutrition plus ferts and now have steady growth, if not a tad weak in appearance.
My question to everyone:
I know Co2 is required in high light situations to keep that balance but am i right in saying that CO2 on low light tanks is a waste of time for the reasons i discovered? Or are there beneifits to adding Co2 regardless of plant choice and light levels?
Reading on a retail website it suggests that even liquid carbon such as Flourish Excel do have benefits to the plants growth, do all low light (low tech) tanks still use Co2 or is this simply choice depending on the growth rate required?
I would love my crypts and hair grass to fill out quickly but adding too much ferts causes algae and adding Co2 only appears to cause some plants to bolt.
does liquid carbon affect shrimps?
thanks for all that read this.
