For you BB reefers! A question?

How about putting some SPF on my SPS

Shaun,
Got ya. But since growth is starting to pick up, is it safe to assume color will eventually show itself. In a sense my tank is still young, through all the changes I never really gave it a chance to really become stable.

I see what you mean by the burning too, but then how do you know when enough is enough? How do you guys notice "burn" on SPS?

Andres, you guys will do anything to use the bunnies huh? lol

 

[ShaunW]

I notice "burn" by a browning of the the coral (similar to how we humans tan under the sun), and lack of colorful growth tips. If you "burn" them enough they will begin to bleach. Remember, many other things will also create this phenotype in SPS, so you need to have a competely healthy tank to begin with to even narrow down this observation.

 

[DRZL]

what? :bunnies:

Kris,

Remember that SPS will grow (and PE) w/ higher than normal n03 present, but color will be less liely to show, has your n03 changed since I saw u last? (aka test)..lol

That is true, I'll decided on what changed have to be made when I get No3 and phosphate test kits :eek1:. Shouldn't be too long, but I don't think I'm burning because tips have the most color. I'll stick to this schedule for now:turtle: .

You could do that or.....provide less light, or feed more. I was giving 6 hours light without feeding much = bad color. I upped the feeding schedule and more growth/color. I guess I could have also feed less but decreased the light period to get the same effect. I'm sure there is a formula for what I am describing, .

 

[DRZL]

but wheres the bonding in that?

It better have, the tank got almost a 100% water change through treatments. PE(Polyp extension?)? No test yet, maybe I could mail you a water sample :teeth:. But we'll see what another week holds for the tank.

 

[DRZL]

one more thing Shaun,

Ive always considered p04 useful for corals, as anything live contains P, I forgot where I read it but there was an article on coral absorption of P, basically saying the more corals u have the more P absorption, hence less P in the immediate enivronment, could it be that p04 strippers and light feeding are leaving this level aftificially low?

One thing I did find out w/ p04 is that when I had it about undetectable and before TM salt (suposedly P rich) my SPS were brittle

PE=polyp extension:thrash:

I was actually thinking of heading over to Anthony at reef exotics to check out that 450G this wknd, would save u shipping Mr. el cheapo..lol:shhh:

Oddly enough polyp extension is really good, you can be the judge of that if you stop by. I'd take a ride though.

I'm not cheap just skeptical about spending cash. Ok thats like my 99th aka Mr. Cheapo:tongue: :Lurking:. LMK when your going you, you, you...i dunno..lol...

Inorganic phosphate is essential for life. DNA, RNA and proteins all are made with it and require it. All marine life growth requires P.

But different species of marine life grow at different rates, and hence, use inorganic phosphate at different amounts to account for their growth rates.

So if you have lots of P your going to stimulate algae growth, because they are able to utilize P better than other marine life due to their growth rate. But without any P, nothing will grow, so you need to find the equilibrium where you have just enough so that the SPS are competing with the algae for the limited amounts of P available.

It's great to see threads like this one and the nitrate thread. There is a link between water quality and the amount of lighting that your corals can take....FO SURE! BUT is it because of increased water clarity with better water quality, or because of a lower nutrient level "starving" the corals?

funny...I was just talking to Heramn about this

Well, whatever it is, I have found, when it's working - keep doing what you are doing.

I recently added another 250 DE halide to my setup cause I changed out my SE 10k's and VHO's - I saw great growth from this original combo. But it wasn't until I added a 4th pendant, and had consistent water changes that I began to really see a difference in my colors and growth.

What am I saying? Once you find it (the forumla Shaun eludes to) stick to it - I have been doing 30g water changes every sunday for the past 3 months and that is working - corals are popping with color and showing regular growth (not nearly as much when I had 10ks, but good growth). Since I am not in a hurry to overgrow my display, I am glad I have the lighting combo I do, with the photoperiod I do (7hrs) with the hsubandry practices I do.

Stick to what they are going to respond to, and steady the course.

I have to go to work lol2: its funny saying that) but will try to talk with you guys about this later tonight.

See what is really cool about this fact is that:
1. SPS can get a "sun burn".
2. That your taking more advantage of the dark period of photosynthesis, i.e. when sugars are being made most.
3. Bomber trooper once suggested that SPS only needs a short photoperiod to acquire the most energy from the light aspect of photosynthesis (photosynthesis actually requires both a light period and a dark period to function) and that any more above a certain point is unnessesary (this actually fits with all the biochemistry of plant metabolism that I have studied). In fact too much light is detrimental. An analogy is, if you were to spend 10 hours in the sun in Miami with out protection, how would you feel?
4. Based on my studies in nitrate and N cycles, SPS actually are able to absorb many nutrients from the water column and succesfully convert them to working energy (growth = color).

Don't agree with the sunburn analogy, and this sounds too much like getting energy for free. A few of us (MCsaxmaster, ATJ) argued with Bomber and his minions )) about this last year in this thread, Run a short halide photoperiod....

Here's another good thread also, So our halides are giving our corals much more light than the sun!.

And a good introduction, Lets talk about ~Lighting~.

I would like to understand why pigments darken when exposed to low light levels and lighten when exposed to high light levels (or increase/decrease population levels).

SPS has a max limit in light needed for successful photosynthesis, anything over is just going to create a "burn". Once the optimum is reached, it is then up to the dark cycle of photosynthesis to use the light energy acquired to create sugars nessesary for growth.

Can you briefly (I know I said briefly :lol explain photosynthesis and its dark cycle.

My "burn" analogy is extremely simplistic. I would define the response of SPS to increased light as a "stress response", in that the SPS in question is put into a situation where it has little or no time to biologically adapt with the present state that it is in (it needs more proteins and different proteins than it presently has to respond, and doesn't have enough energy or time to make them). In then responds by illiciting defense mechanisms.

I haven't read the threads you linked to but I will scan them over.

Of course, please! They are all interrelated, .
