I found this product to be a must have in the marine aquarium filter system it takes up very little room in the external filter or can even be placed in sump.
After a few weeks of using this product I found my tank PH stabilized also
They do everything that is claimed and you will not regret purchasing them
before using these Nano Tech Bio blocks I used ceramics they did nothing for the bio load on my tank so I changed to Siporax another product that claims did not flourish or handle the bio load but after changing out for Maxspect Nano Bio Blocks I have noticed the difference and the bonus is they take up very little room.
One very pleased customer I would highly recommend these to anyone that looks after marine tanks if starting out or a pro that has been loving the hobby for years.
