Hi 姚俊 ,
As you ask, : 改善左幾多？我想知係咪換上同與環同體積的matrix都能有大改善？
Well, it's hard to measure the improvement cos I test water after I use new biomedia. Sorry. By the way, as described, the total surface area of Matrix is 40 times of bio-ball !!! So, by my naive calculation, it should be 40 times effective than same volume of ball, right ?
I placed Matrix in high water flow filter, and packed de*nitrate in bag and placed on the surface of sand-bed where with fewer water flow, just behind life-stone.
Also, I use SEACHEM PhosGuard too, to remove red hair algae. It's work, but slowely. I will also change to use SEACHEM MATRIXCARBON to replace original cheap active carbon that using cos I suspect cheap carbon release phosphates that glow red hair algae.
------------------------------
Some description :
PhosGuard™ is a high capacity and high efficiency filtration product for removing phosphates and silicates from marine or fresh water aquaria. Unlike competing products, PhosGuard™ is bead-shaped for optimum flow characteristics and has an exceptional porosity for enhanced capacity. PhosGuard™ has a working capacity to remove 20 to 60 mg/L phosphate in 100 gallons with a similar impact on silicates. It may be used continuously or intermittently, and will not release removed phosphate. PhosGuard™ will cause a decline in hair algae and enhance coral growth. Each liter treats up to 300 gallons. Marine or freshwater use.
