Effects of MH lights on Coraline algae

[RedSeaReef]

This tank is foul

[vahan1990]

your aquarium needed calcium

[csilightning]

You have too many phosphates , and your green hair algae is growin over the coraline algae and keeeping it from getting light. You need a sea hare to get rid of that algae. also get a liquid phosphate remover your water will be milky for a few days but its worth it. your coraline algae will quickly return.

@csilightning Its not hair algae, its a species of Caulerpa macro algae that got free from my fuge into the main tank.

your lights could also be TOO close to your tank. i have my MH system 2 feet above my tank and i have SPS growing in the sand bed.so that would be 4 feet of penetraion from top to bottom. so try raising your MH.

probly more to do with water params than anything.. how come others dont have this problem?

[lungbo]

too much light! rookie mistake! I learned the hard way! buying the most beautiful coraline encrusted purple and green mushroom rocks. 1 month later they were all dead???? so now i have no more than 8 hours a day especially with halides. Nice tank though just don't let that algae take control.

[moneymarkj]

Hey buddy,don't think metal halides is the cause of your coralina algae bleaching. is

[hugo2x]

@moneymarkj It did. A new species of coraline regrew after 2 months

[moneymarkj]

@hugo2x 2 months after what? New lighting?

[Robertsclub]

yeah! that is good!

[Robertsclub]

how long you let it run (light) , cuz if u runing your light 8 hours plus , its to much lightning!

[hugo2x]

@Robertsclub about 6 hours a day

[kastarock]

how many l/h the bomb?

[31668999]

i gotta metal halide and a coral super grower in a little foot deep hexagonal tannk and getting amazing growth on sps corals including moties, acropora and chalice. significant growth is within a week.

[hugo2x]

@31668999 yeah, its hard to beat the power of MH bulbs

[myangel833]

What kind of rock do you have in there?

[hugo2x]

@myangel833 Tonga branch and Fiji

[MRBUMFUZZLED]

1 it's probobly the bulb get a nice 20k

2 bump up the cleanup crew

3 take out the fish/ corals and clean the lr and sand in freshly mixed saltwater that will solve the for the food source for the algae

You should never have a problem with mh's

[jessetattoo]

you may wana buy a BRAN-new light as it looks like that one is puting off too much yellow spectrum witch in turn is helping your hair age grow like a MF

[hugo2x]

@jessetattoo Its not hair algae, its Caulerpa macro from the fuge. This stuff is such a pain! My yellow tang is doing a decent job holding it back though

[donsjuand]

Coraline algae prefers medium-low light but can also do just fine with higher lighting assuming green algae doesn't out compete it. I would fix your nutrient levels to discourage the green algae from out competing your coraline. That will allow the coraline from living spores in the lower light areas to spawn on the higher light areas later.

[lastlane]

loving that zoa colony, do you think you are going to switch back to pc lighting?

[hugo2x]

@lastlane Probably not, Its more expensive to replace multiple PC bulbs than a single MH. Also I love the shimmering effect of a single light source.

[funkmaster100]

how bigs ur tank how many watts is ur lights what do you dose

[LordoftheReef]

Your purple will probably come back over time. Any increase in light intensity tends to do that with coralline, it seems super sensitive to lighting changes.
