  2. Hi I have a waterbox 15 aio aquarium and it is currently stocked with fish and corals. I was wondering if it would be possible for me to add a sump, and if so, how should I do it? I know I could either drill it, or have a hob overflow box, but I feel like drilling it would be complicated. I also know that hob overflows are unreliable and bulky. Any type of help and input would be greatly appreciated. Thanks

    Color and growth influenced by water flow

    Anything change with that colony you originally posted? Got a buddy who's got great color and growth from his sps... but they're thin branched and not the best polyp extension. Flame angel could be a polyp extension culprit... among other things... but the thin branched growth makes me wonder if its it's a flow pattern/strength issue.

    Bump. What surprised me when I showed the pictures to Dana Riddle was his comment that this was the first photographic evidence of water flow being the influencing factor in coloration.

    I have 14 fish although smaller fish. maybe i need to cut the fuge back, although its really saved me from algae and issues in the display big time. i guess i can cut the sea lettuce out. its a phosphate magnet from the start. Ill pull it tonight and see what kind of difference that makes.

    I would say there is a good chance the fuge is overkill at this stage of your tank lifecycle. It looks like you have hardly any bioload from the pictures, so in that case there is not much in the way of excess nutrients to be consumed by the fuge?

    I am running a big fuge, well roughly 20gals give or take, with chaeto and sea lettuce. I've cut the lighting to help some.

    SPS turning green

    Well, in addition to my comments and links in my first post above which are still good. The production of flourescing and chromo proteins is very dynamic. There are multiple factors or variables at play. Dr. Salih, in research published in this paper 15 years ago, clearly showed a link in fluorescing protein production tied to light intensity. At intensities too high for the zooxanthellae proteins were made to use as photoprotection, at appropriate levels coral were brown because they didn't need to protect their zooxanthellae and at low levels proteins were made to inhance light to their simbionts. So changes in intensity can certainly effect a shift to green. Additionally age can be a factor as in this Povona cactus coral where the new growth is significantly brighter and greener than the older parts of the colony: Here's an example with polyps with two different color forms. The older polyps are dark red with lighter red mouths and the younger polyps are green with red mouths. This difference in colration may be associated with differences in zooxanthellae clades (like in this video) or may be age related and similar to what's seen with branching type corals. The green and red polyps just below and left of the top is where a rock fell on it, killing the polyps and regrew. And in this post here, I posted pictures of an acro that showed different colors influenced by water flow

    I was reading various replies to this same question yesterday on a national forum. A few folks said that substrate and rocks can absorb PO4 to a certain degree, especially in newer systems. The other thing mentioned is that heavy skimming can remove phosphate via skimming out bacteria that are consuming the PO4. And I scanned back a little but did not see this: are you running a fuge with any kind of algae? That can also be consuming PO4.

    I'm really sad that nobody noticed I was just rehashing what was said in this thread years ago when I replied today

    Corals adapt the zooxanthellae within their structure to changing lighting conditions. EcoTech has developed research into how corals respond to different temperatures and used that research to create light settings within their products (see attachment). I'm assuming a lot of companies in the industry perform similar research, but I'm not sure who was the first to give proper credit. Anyway, most corals change colors from tank to tank mostly due to lighting conditions in different placement areas. Acans and brains are famous for changing to completely different colors and that's why they're seldom named corals. SPS retain colors more readily, but can also change in reaction to less/more light and different PAR levels. IME SPS turn green/brown with predominately yellow/white light in the 2K-5K range and with high nutrient environments. I personally enjoy 18K for viewing. ReefWholesale_CoralLab.pdf

    I cant seem to keep my phosphate up. last week it was .03 from undetectable, i fed heavy for several days 3 times a day, i reduced fuge lighting to every mondays thursdays and saturdays. thinking it would be .05-6 and i would be happy, checked this morning .00 i have not done a water change yet on this system in 3ish months. i dont get it. any ideas?

    Do you use GFO? GFO is an iron-based product, but honestly I am not even remotely an expert

    SPS turning green

    How would you get high iron if not dosing and using a basic salt like instant ocean? Some of my frags from when I first started are still green. Frags that I’ve gotten over time once the tank somewhat matured stayed the colors it was suppose to be. So was just curious if they would ever color up Sent from my iPhone using Tapatalk
