I use it on my 38, 120 and my 180.
It's cheaper than Eco complete certainly and most other harder sediments.
So I really do not think cost is really an factor.
If you can afford a large tank, but cannot afford sediment, or lights or CO2 gas etc, it might be best budget better and chose an appropriate sized tank.
Some use sand, works.
Hard to beat the price.
I think the owners are most to blame for the cloudy issues, it takes some getting use to and pruning methods are sometimes an issue for some folks.
I'm fine with it.
