Diatom Bloom

[Jimm0425]

I have a 1 year old 180gal reef tank and I upgraded from pc to acan led in december and i got a bloom. my parameters are all good and have been doing consistent 20 gal wc1/week.
sg 1.026
pH 8.2
dKA 10.2
cal 48
mg 1500
nitrates 2
PO4 non detect with salifert
ammonia/nitrite 0.0
temp 80

My RO cartridge is 1 year old and I'm getting ready to change.
Is this unusual?

No not unusual, it is probably due to the new lighting being much stronger than your previous lighting.

Keep up with the water changes, maybe do an extra 10g for a little while.

Do you have a TDS meter to test your Rodi water?
Also - are you running any reactors with GFO or carbon?
Do you have a decently sized clean up crew, they should help with the diatoms.

I am running GFO and got a cleanup crew from reefcleaners.org a few weeks ago. I work for a company that has a water lab so I will bring in a sample and have them run it for everything
