Convenient to use, easy in installation and free from the trouble of CO2 filling.
An essential product for a planted tank. Plants grow really well. The only draw back is that additional cartridges are not available easily. Even till today I have been hunting for cartridges. Every store or online platforms have the complete Kit. I even contacted ISTA. But they routed to same dealer/seller.
Super,l am fully satisfied by the product.Good one
