Diatoms Diatoms More Diatoms

[ovrmyhdagn]

I have had trouble with diatoms for 5 months atleast.
I use RO/DI water, I increased the flow in my tank with a maxijet 1200.
I changed out all my LR and removed my crushed coral and put in sand from an established tank. My lightbulbs were changed last week. I only feed once per day. I do have a heavy bioload at the moment.
Any ideas? I been thinking about the nassarius snails.

Nassaurius snails are great for sand beds.
Can you list your nitrate level for us?
How about the phosphate and silicate level of your RO/DI water.

How would I check for phospahtes and silicates from my RO/DI water?

 

[lion_crazz]

Get a phosphate and silicate test kit and test the water that it puts out for you to use on your tank.
When was the last time the RO/DI membranes were changed?

Right at a year, but I have only been using the ro water recently, before I was getting it from walmart which has been known to be poor quality.
Kent marine maxxima

I have the same problem use ro water and a uv sterilizer also. Did water change same problem any help? I have a 92 gal corner tank with wet dry filter. Had tank going on 7 years.

What is your nitrate level?
What is the phosphate and silicate level of your RO unit?
When was the last time your membrane was changed in the RO unit?

Yeah I had problems when I first started my tank, Now my clean up crew is doing a great job, the snails mentioned before are great, as well as some turbos and I have a bunch of crabs. the sand is amost totally clean, It could get a little better, but the LR is looking great! So my suggestion to you is get your nitrates is good order if they arent already and get a crew, or get some more!!

Had water tested phosphates were less than .25 ph level 8.2 and the amonia and nitrates were ok. also the ro unit is new.
