Recently I have been getting a daily dose of cyano & micro bubbles on the LR and sand bed.
I have three tanks plumbed together. I have a Deltec APF600 in a 30 gallon sump plumbed into a 40 gallon refugium plumbed into my 90 gallon display. It's all on one level in the basement. All the bulkheads are approx 2" under the water line. There's 1.5" bulkhead from the display to the sump, two between the sump-refugium and one back to the display. I use an 802 powerhead to push water back into the display and gravity pulls water form the display back into the sump. I'm using two 802's in the display plus a 301 powerhead.
In late December I changed my MH bulbs from ARC 250w 20k to Ushio 250w 10k. I also changed my return from the refugium to the 802 powerhead from a 302. Since that time I have been getting red cyano and micro bubbles on the sand and rock; so I'm in the tank almost daily scrubbing around with the toothbrush.
Any advice or ideas?
