What if I placed in my HOB filter That should spread the dissolved CO2 more evenly. (What do you think?) It mostly a trail run 48 tablets in 48 days what happens. Am getting bored by just sprinkling 1.4ml of excel on the surface of the tank.
Doing this will help spread the CO2, but my point was that little CO2 will dissolve into the water column in the first place.
Excel is going to be much better in this case.
According to the recommended dosage of the product (Hobby Sanoplant) it states to place one tablet per 50 liters once every week.
Manufacturers say/claim many things. If you want, you can try to use this product; I am just advising that you save your money.
