Bad rock causing multiple cosmetic problems

[ridinfast03]

Hey guys, I'm really not that new to the hobby, but I am having a diffucult time with a two of my new additions. One is a 29 which I will post pics of and the other a 75. I got some fiji liverock in that I cured seperately in a rubbermaid with a decent skimmer for approx. 1.5 months. The tests come up pretty good and I added it to these to tanks. The 29 is full of black cyno or which I think is cyno and the 75 has the red type. The 29's levels are great: 0 phospate, 0 ammonia, 0 nitrate/nitrite, higher calcium level, 9/10 dkh, and the ph is bouncing between 8.1 - 8.4
There is a phos reactor running with a 8th of the suggested amount of media and a bak pak skimmer running and a hob filter for carbon.

The 75 is close to the same expect there always is a touch of nitrate- maybe 5 ppm at most, and the skimmer is much larger.
Salinity is 1.025 too on both tanks. Both tanks are getting good water changes (10%)about every four days.

Does anyone know if RC lowed the file size for pics again. I'm not unfamiliar with resizing and lowering quality, but having troubles getting tank shots that low.

Hey rob - the easiest thing to do is to go to photobucket.com and you can upload huge pictures, then just link to them with the img tag.

cyanobacteria usually forms when there is not enough waterflow. Anytime I've ever had a problem with it that wasn't nutrient related adding a powerhead or 2 cured it pretty fast. Get a Tunze if you can afford it or try some Seio pumps. They're dirt cheap off ebay compared to the lfs.
