Would like a few tips or suggestions

No it will be thicker next week.

Yes I see it is growing faster already. I appreciate your guidelines for these filters. I am thinking diatom bloom in tank is subsiding. I have red turf algae in tank and found turbos work great on them.

Thanks again!! I think I am on my way.

Next week as a thicker mat of diatoms that easily washed off.

I turned off skimmer now and GFO. Will speed up of course. Water does appear a bit dusty. Slow transition does not appear to cause stress to sps corals.

The GFO is the only thing that would affect the growth, since it reduces phosphate. Also, a slow transition is not really needed, because you are only increasing food, and decreasing nutrients; you are not changing temp, salinity, etc. But good to see it growing more.

My concern with a fast transition is the diatoms wash off almost compltely, and while it contains many tied up nutrients, it is also a clean scrubber with no algae for filtration for 1-2 days now.

Also washing off the screen made the screen cling better. As week progresses the spray increased.

Got Tunze 7105.50 pump for X-Mas. It is a DC controlled sump pump that can create a surge effect. I am going to experiment with slightly larger 1/8" kerf on slit and then surge and normal flow rates.

Control is through devices like Neptune Apex or Tunze Controllers. Neptune may have advantage in surge times and delays. DC back up relay will save algse in event of power failure.

It is overkill but I have learned this stuff hard way in lightning belt.
