Rated 5 out of 5 by AAK1 Excellent for the lazy aquarist
These easily concealed cubes slowly dissolve and keep the pH , alkalinity and calcium levels fairly stable, enough that I don't have to do such frequent testing. I can just look at the cube size to determine when to add another. The very occasional "spot checks" with the test kits show that the cubes are working. Just be sure they are in a quieter area of the tank or they will dissolve too quickly. Good for fish only or soft coral aquariums. If you have a heavy load of actively growing hard corals, you may need to add additional supplements to keep up with the demand.
If you have nitrate/phosphate overload problems, then the added trace elements from the dissolving cube(s) will give any (already present) nuisance algae a real growth boost, however. Control that nutrient overload/algae problem first!

Rated 5 out of 5 by fishwillgrowheretoo Great stuff !
Love this stuff. Pre-measured and easy/quick to use. The ease of use is just another tool to help you keep parameters where you want them.
I like the visual aspect, because at a glance, you can see what's going on. If they are dissolving fast, you need to do maintenance checks quickly. On the flip side, if it's slow, your water is usually in specs, or close.
Don't mistake this as a replacement for due diligence, but it's like I said, its another tool in your arsenal !
