Phos-Zorb?

Hello to all, this is my 1st post.
I have been using Phos-Zorb in my 20 gallon heavy planted tank for the past month with great success. My water is clear and I have cut down on almost all my algae problems and my plants are growing like mad. I have scanned threw the forums and have not found anyone one else using Phos-Zorb. Am I doing more harm then good in the long run? I was told to not use activated carbon by my LFS.
If anybody has any input I would really appreciate it.
Thanks in advance

Plants need phosphates. It's been shown that phosphates are not the root cause of algae as they were once believed to be. I have 1-2 ppm of it in an of my tanks at any given time, but others have more.

If a person has a ridiculously high amount of phosphates, in their tap water for example, a phosphate reducing product might help get the phosphate level to a non-ridiculous amount, but you don't want nil phosphates either. Although phosphates are needed for plant growth, at some point having more does not induce better plant growth, nor does it particularly lead to any problems in marginal excess. Phosphate removing chemicals don't differentiate between a healthy amount of phosphates and a possible less- than- desirable amount, however, as it will seek to remove ALL phosphates.

Have you ever tested phosphates to determine a need for a phosphate reducing chemical? Things may be working alright now, but you might find it difficult to maintain your current success if you're limiting phosphates too much. If a person is seeking to limit anything to reduce algae, usually reducing lighting is more desirable. This will reduce the nutrient demand of the plants and give more stability to the tank, especially if the plants are not intensity hogs in the first place.

A person does not have to have any sort of chemical filtration if there is no particular need for it. Carbon is good for some things, but myself and many others have found it to be purely situational and optional.

What sort of algae were you having problems with before? Phos-zorb removes silicates as well, so maybe you had some algae spurred on by an excess of silicates?

Phos-zorb is primarily for fish-only type freshwater tanks or marine tanks where phosphates do not particularly serve a purpose if not being used in a buffering capacity.

I had big problems with green/cloudy water. Did black outs, water changes, nothing worked. But since the Phos-Zorb my water is crystal clear. Though I have not checked my phosphate level and I guess that worries me. I was going with the recommendation of my LFS. I am not sure what my plan is. I was scanning the forum for proper media for filters with not much luck.
Thanks

the guys from nyc might chime in. NYC's tap water does contain phosphate. i think they add some form of PO4 in the system.

You might want to check other nutrients & condition though, like lights, CO2, ammonia (should be 0ppm)..
