interesting but has nothing to do with our tanks.

[bitts]

i find myself wishing that we had fosi to weigh in on things. his guidance was always appreciated.

I wanted to post a couple of my latest macros from John at Reefcleaners

 

Pink galaxy

 

Sargassum

[animalmaster6]

I love both those macros. Does the white tips on Pink Galaxy show it's growing?

[bitts]

not sure if ive already posted this one or not its about light absorption as depth incresses & how this is messuered. one tihing i would like to establish is the needed light for each type and what depth that relates back to.

a little more

closer but still not what im lookin for

now were getting somewhere

how every starting to go a little off topic sorry.

 

 

awesome but not sure about it may edit out soon

not sure....it always has white tips, even when it isn't growing.

 

bitts is awesome

[bitts]

macros release carbon dioxide at night, (and during the day) as a result of the Calvin cycle. It is referred to in the hobby as the algae's "night cycle", because during the day the algae releases more oxygen than carbon dioxide. At night algae no longer releases oxygen, so the net results is a release of carbon dioxide lowering ph. It isn't drastic, and it shouldn't be a big issue. When algae starts to die however it releases a good deal of carbon dioxide and in a crash situation with the death of a large specimen in a poorly buffered tank the change can be large enough to cause a chain reaction among the remaining algae. Adequate surface agitation, and good room ventilation is therefore a good idea and should take care of it. A fall in the drain before your sump if you have one will help, I realize your tank probably won't have one but others might be reading.

John could you go into more depth about the calvin cycle. It sounds very intresting & is aore than likely to be use full.

I am very interested in this as well.

Oh cool. Never jnew that

 

and +1 to Bitts being awesome.

[bitts]

OK now I know this will seem unrelated but for those who are planing their tank around those funky tree's. this may actually be of interest.

I'm sure there are things to steal. perhaps by using the mist to counter evap. or other ways that we havent thought of yet.

[johnmaloney]

hey bitts can you have to fix my quote above to read "Adequate surface agitation, and good room ventilation" i am good for typos

 

So my understanding of it is that during photosynthesis oxygen is released and sugars are stored, when those sugars are used to provide what the plant, (algae can be called a plant it makes thing easier), needs such as a cell structure or compound or energy etc...the result is a process which release some stored carbon dioxide.That cycle is independent of light in the sense it can occur when there is no light, but it still needs photosynthesis to create the sugars that will eventually be broken down. So the process is called the "dark cycle", but really occurs 24/7 and as a result of photosynthesis, but it doesn't require light.

 

Did that make sense?

[bitts]

thanks john, going to look for pdf's on calvin cycle & Liebig's law.

[got2envy]

Wow! that is very interesting stuff

My red grape releases CO2 bubbles before the lights go out...in fresh water planted tanks it's called "pearling"....this is the only macro that I see does this so far.

 

I <3 pink galaxy! def one of my faves so far let's see at what rate it grows.

[johnmaloney]

Liebig's law is about limitations in growth, it argues that a plant will only be able to grow until it is limited by one particular nutrient. (okay it doesnt argue that at all, but the principles were applied to agriculture with great success and etc....they illustrated it by filling a barrel...you can only fill it to the first hole, no matter how tall it is).

 

So lets say you have all the nitrates in the world, but no phosphates...plant can't grow b/c it needs phosphates. Introduce phosphates and things take off, keep them out and they don't etc.. works with light, carbon, the major and to some extent I guess the minor nutrients.

 

The nutrients by the way, (and you will find more comprehensive lists if you look around) is somewhat like this:

 

Major Nutrients -

 

nitrates

phosphates

potassium (comes in potash alk supplments)

calcium - for the calcifieds

magnesium - mangroves need them, they need to be in balance to keep your other parameters in check. I am sure algae uses it on some level, but I am not sure it would get so low in an aquarium as to cause issues? anyway just keep it around 1200.

Sulfur - dont ever dose it, or at least I wouldnt. Algae seems to go sexual around to much of it, I think it may remind them of dead zones and triggers sporolation. Dying portions of algae will provide it usually, or mud substrates and even water changes introduce some sulfur. Sulfur is necessary at some level though for healthy algae growth.

 

Minors - water changes

 

Boron

Iron - I think it is more important than a minor when it comes to certain green algae just an opinion...

Manganese

Molybednum

Zinc

[briansbelle]

John, you say macros need phosphates to really take off, so would it be ok to use the "bad/waste water from my ro unit to top off my macro tank?

 

Am sure there is plenty of algae food in there lol!

 

Also my flame algae puts off some crazy bubbles lol!

[johnmaloney]

oh i was just using an illustration. the phosphates that come from the natural process of your fish eating and using energy etc... should do it.

[bitts]

Should the phosphates in frozen food be allowed to enter the tank. Or is it recommended to maintain normal husbandry on this.

Depends on the productivity. If you have a lot of light, I'd encourage thawing food directly in the tank. Plus the added food will benefit many of the infauna and other smaller organisms that would normally starve. If it is a lower light, lower growth setup, you'd want to balance any input with the productivity/export. That may translate into some rinsing on one occasion, and none on the next. I know in my setup, I've had trouble maintaining levels high enough to satisfy demands, even with lots of food input.

Hello Everyone,

 

I'm looking to see if anybody can help me out with an ID,
