Spectrum

[blaked]

im having trouble with green algea, the brown diatioms algea has came and gone.
and yes im using tap water, treated.
iv been looking at alot of set ups and noticed alot more blueish spectrum than my lite.
i bought the hopar 6x39, 3 act,3 10 k,
should i replace a 10k with another actnict?
i will be using revers osmosis water from here on too

 

[Dr BlueThumb]

the rodi will help.

How much bioload?

info on:rock's?skimmer?waterchanges?refuge?inorganc level's?


What kind of bulb's are you using?

The only bulb's I would use would be guisemen or ati

The blue light's  par reading is very high on the 20 000k.  3-10 000k and 3 attinic's should give you a good balance.

but if like the blueish total look and wanted to cut back on the growth of algae you could add one more blue. imo it may be too blue and mess with your eye's when your viewing the tank.

the blue lights grow algae just as good as the whites, you must use rodi water not just ro, the algae loves phosphates, nitrates and silicates which are found in tap water.
po4 is in a lot of foods, you should run gfo

i have a prizm skimmer getting green stained wet skimate, the bulbs in my fixture are factory hopars.
im under the adequet level of live rock....
what is gfo ?
thanks

 

[Cal_stir]

granular ferric oxide, phosphate remover, best used in a phosban reactor

 

[Cal_stir]

are you adding phytoplankton to your tank?

 

[blaked]

no phytoplanton has been added to my knowledge .
i am also using filter floss in my refuge to trap the algea i do clean off, i clean the display tank
4-5 times a day, rinse and clean filter floss every 2 days.

Algae imo favor the  warmer colors

When buying bulb's to grow algae, a lot of people use under 6 500k. 

Most coral like cooler temps, above 6500 k, closer to 10 000-15 000K

at least from what I read so far I may be wrong thou.

 

[blaked]

yeah ima noob but i know that the deeper the light makes it the more blue it looks due to colur difusion,
so id guesse its all on the type of ecosystem im trying to re create.... be it deep water lagoon or shallow bay.
the temp of my water is also 82f trying to rid my damsel of ich..

 

[Cal_stir]

Dr, you are correct, but when your dealing with nuisance algea, just about any light will grow it, you have to eliminate the nutrients that are feeding it

 

[Dr BlueThumb]

For sure, nutrient's/inorganic's is a big factor as well. it take takes 2 of them to tango.

 

[blaked]

is filter floss doing more harm than good then ? dumping nitrates into my display tank ?
i rinse it realy good, and drain it very good. in tap water

 

[Seggsy]

For algae, I've always looked at a few things:

bioload (amount of fish)
feeding (more = more algae)
skimming
age of bulbs
amount of time bulbs on (I think I am rare at only 7 hours)
type of water going in (RODI, and check the TDS often)
amount and frequency of water changes

Good luck

yeah thanks for the great info, once i get some good algea rockin i should be all set.
