Feeding corals micro-nutrient-rich foods...

I'm continuing to get really extravagant growth with (admittedly easy) euphyllias, which have taken over my tank. The curious thing is---they're continuing to double every few months despite a period when, due to a serious illness in-house, I couldn't spare more than a minute to feed and no time for maintenance for 6 months.

This should have spelled, if not disaster, at least a slow growth; but they go like mad.

So I asked myself what I was doing. 1. I drip kalk, and that never stops, so they have plenty of mg and cal. 2. I had no time to get to the lfs to get proper food, so I took my koi pond krill, ground it up in a mortar, and threw it in once daily, thus feeding both corals and fish. 3. even the 4 popped heads that have been floating around since my tanksitter had an issue regrew skeleton and became new corals. That's it.

Then when the crisis eased and somebody asked me how I got popped heads to regrow---I got to looking at what I was doing---which was not much; but I got to looking at the effect of missing water changes, and what I'm feeding: notably---the nutritional content of krill. Selenium, boron, all those micro nutrients that a salt mix supplies, in a balance equal to what the major food source in the ocean contains.

I just offer this for two reasons, one, that it's odd, and might offer another insight into how the ocean distributes food---ie, what's coming directly from the water and what's coming in via consumption of fish who've consumed krill; and two, that it's not a bad regimen for somebody who's broken an arm, run into a crisis of some kind where they can't properly care for their tank. Euphyllias are sort of like green star polyp in some regards---grows like mad; but they sure didn't take any damage from the situation. Neither did my fish. I now add other foods, because my fish appreciate it and I think variety is better for them. But I continue the ground krill, every few days.
 
None of my euphyllias seem bothered by periods of me not feeding the tank. I have 2 large colonies of hammer, one huge, all from the same small colony, and a huge frogspawn and torch. It seems they grow faster the larger they get. My hammer colonies are the branching type.

I used kalk, but after a near disaster with an overdose, I've switched a Calcium reactor for the past 2 years.


My fungia seem to benefit from feeding coral frenzy and reef roids, as my brown for years plate, turned green with purple edges after a month or 2 of regular feedings.
 
I own Coral Frenzy, but nobody but the fish seem to like it. Reef Roids is new to me.
 
Interestingly the gut content analysis done on most corals that I've seen has always had a high proportion of "parts"...aka fish poop. Feed fish, fish poops over coral, coral eats poop :eek2:
 
Interesting: I've also seen an article saying that bristleworm poop is another biggie esp for sps, that they break waste down to a particulate size that goes nicely into coral mouths. Got plenty of fishes and bristleworms, me. ;)
 
The joy pond krill sound interesting. Did you notice any effects on abhor the other corals? Wondering if it would be worth getting some and trying it out, can't hurt I gather. Not many corals currently, but do have some acan frags, leathers, and a sun coral. New frags on the way too, so any extra help they get would be awesome.
 
For the sake of my fishes I feed occasional mysis, formula one, and formula two...the blennies and rabbits need formula two, and krill is not their thing. But their poo, with yet another set of nutrients, goes to the corals.
 
Spell check :headwalls:

I was thinking in addition to the food they get now. It is a mixture of prime reef and pemysis. If this koy flood would help cut down on the need for phyto or marine snow it sure would be cheaper. Not a total replacement by any means, but a hangs from time to time.
 
keep an eye on your phosphates while feeding something like that. check out the 'crude ash' or 'ash' content. That is phosphates, essentially. Most corals do NOT eat phytoplankton, and when I used to use it, my neptheas and toadstools got bigger, while a cyano outbreak started to occur in my tank (i have also been told that marine snow is garbage, although i have never used it and some people SWEAR by it I guess). I suppose this system works for many types of euphyllia, seeing as though you have had such good luck with it, but im sure SPS would suffer from excess phosphates. It seems like a pretty good idea, especially for smaller polyped lps corals, to feed powdered or ground up food. but I'm sure it makes your tank much much dirtier to the point where certain corals may not look as colorful or grow as fast. I feel most of your growth is attributed to your fairly constant alkalinity you were dripping, though.
 
Careful feeding koi exclusively on krill. I do feed something similar to Coral Frenzy from Blue Zoo Aquatics. Anthias, fish like mandarins, and corals seem to enjoy it, larger fish not so much. For me proper lighting levels and current levels seem to be the key to coral growth.
