Not so good. I use Jabbo very well, which is economical and practical. The classic surge mode works best. Cylinder WP- 10 is lower than 60? WP-25 is used below 120, and the effect is quite good. Many models are useless, because only one is the best, and the others are decorations. Some people are not well equipped, but corals are well cultivated. The reason is that aquarium equipment is not a well-researched industry, and expensive equipment is not necessarily good. If the industry is very mature, people with low level can raise well as long as they have good equipment, which shows that the industry is very mature and has reached the era of fools who do not need breeding technology but only need equipment in place. So buy if you have spare money, and buy a good price if you don't have spare money.
