ViaAqua 10gallon...almost 1 year

is that a meat polyp in the top center of the tank? awesome tank btw

thank you....i think so....open brain, doughnut coral, meat polyp...not sure how to tell the difference...it can get as big as a frisbee!

cynarina is what it's called. i know cuz I just ordered one online

Harmony in bue colors. Did you used some color correction - I mean, coraline is blue.

Is there space between corals and side glass - for a glass cleaning, what are you using for it? Permanent problem for me - or half-empty tank, or no space for a glass cleaning.

What filtration you have to keep up with open brain feeding?

i usually don't need color correction....i think the coralline is picking up the actinic blue lamp. i didn't ever clean the back wall...but the sides were kept clean with the mag float almost every day. now i only have 2 1.7 gallon picos which are only 6" deep (water) excluding sand bed. They don't get algea but sometimes phytoplankton dust that can be cleaned with a toothbrush. i used the smallest penguin filter for filtration back then with filter pad removed during feeding.
