Have u checked ur phosphates? I had that problem with diatoms and adding phosphate remover to my filter worked.

are you using RO/DI water? big water changes will usually bring them down but still need to find the root cause

 

[melosu58]

One of the big causes of diatoms is silicates that come from using tap water. I work at a water treatment plant and know that is added to treat water.

Would this be a suitable unit ?

 

[mr_X]

no. you want a R.O.D.I., not just a R.O.

Aquarium Water | Reverse Osmosis | RODI Water | ReefKeeper Water | Compact III 75GPD with DI Bypass Assembly and TDS Meter

Why wouldn't a RO unit do it and I really have nit got that kind of money I could afford an RO unit but not RODI :/

 

[westy101]

Is this any good ?

I would save your money and buy a 4 stage RO/DI when you can rather tahn buy that and later want to buy a RO/DI.
