macroalgea?

[tigershark]

Hi All Macroalgea keeper out there, as we know, macroalgea could help to reduce/control the level of nitrate in the tank, however, due to the nature of macroalgea which needs CO2 to convert the nitrate to sugar, they need light and CO2, may I know whether should i be using any CO2 for the macro algea to grow better?

Also, if my macro algea is keep in the refugium in sump which contain 5" of DSB, will the lower level of the DSB establish with nitrification bacteria which convert nitrate > nitrogen? as they need water lack of O2 but the microalgea produce O2 during photosynthesis proccess.... adding CO2 will help the nitrification proccess to improve? hope you guys can undestand what I'm trying to say as my command of english is not that strong....pls advise.....

Don't think you need CO2....at least mine don't

These are algae not plants.....and although they so require CO2, don't think it is advisable...........you might get a tank full of hair algae if your nutrient is high like in freshwater

Another point....you will lower the ph of the water which is not good for the inhabitant of your tank.

i c..... what if the CO2 injected is in very small amount? only injected into the compartment where i kept the macroalgea? will it bring in more harm and good?

Bro,

What is macroalgea?Where to get them?Any pic to share?

Thank You

If you decided to inject CO2 into your tank water...make sure that you have a solenoid valve connected PH monitor.......PH must not drop below 7.8.(think that about the lowest you can go without causing any problem)

Do search on caulerpa...this is the most common type.

for layman like me.... they are more or less plant, common macroalgea that could be found in LFS are fern, grapes, turtle weed..... the are acting the same like normal plant did.... they fotosynthesis n consume nitrate in the water during the proccess....

macroalgae dun need CO2 la.. i think with sufficent lighting it will be fine le..

yeah? and algae is different from freshwater plants...

hi,I don,t think CO2 will help because my calcium reactor output is dripping in refiugum.

The output is disolved CO2 with low PH 6.8.

Yet the caulerpa (fern or grapes) still go asexual.Still trying to understand.

Run yr refugium on a reversed light timing as yr main tank. When the lights are off, CO2 will be given out by the algae in yr main tank and absorbed by the refugium.

Think it is a natural cycle.....

Mine go that direction about once or twice a year......

Keeping the parameter stable will prevent it from happening so frequently

i c.... better not try to be hand itchy then...

[blacknails]

Yup... My macroalgae thrive very well with just good lighting and some nitrates.. I haven't heard of anybody injecting CO2 into marine tanks so I don't think it is required.. besides, CO2 would surely affect the pH and other parameters of the water...

So.. IMO no CO2 should be added...

But it's just my 2 cents worth lah.. Hope it helps..

It's possible in small amounts..if you want your macroalgae to start bubbling like planted tanks..however...pls take note that it will not be good for the calcification of hard corals...
