well algae wise you have to take certain things into consideration...
1. how old is the tank.. in the beginning of a tanks life, it needs to mature and will go through (most of the time) all algae phases...
2. nutrients/phosphates in the water. the nutrients and phosphates gets in the water by overfeeding, bioload (livestock) overstocking.... this usually is a cause of algae in a new or mature reef tank..
3. continued from #2 is water... some will say they had good luck with tap water... i disagree to the fullest.. even though ur tap water tests low on the water tester u still have many metals and chemicals in the water that will also promote algae growth.... RODI will help on all accounts...
next, ways to help with algae...
- let the tank mature if its new... usually this could last from 2 weeks till 2 months usually... i think the lil algae i had (the brown one) lasted only about 2 weeks to a month. It was a new tank.. but i would be scrubbing it and never let it just sit there... cleaning the filter
sock every other day or 2.
- a great skimmer will take out most nutrients out of ur water..
- water changes also helps a bunch..
- feed less, low bioload (less fish and stuff that poops) in the beginning at least.. this helps out tremendously..
- RODI <--- the only water my reef gets....
these are some of the many ways to defeat algae.. again if this is a new system u have to give it time to mature... almost every tank goes through its algae cycle in the beginning.. patience and great husbandry is key to a succesfull algae free tank.....
coralline algae usually grows well for me i have bright lights and pristine water quality... by pristine im talking no phosphates and very low nutrients... skim the crap out of the water... coralline is usually an easy thing that can take off in a tank with near perfect par. such as at least 350-450 calcium and 7-11dkh in alkalinity.. as well as ur other par. being near perfect as well.. such as magnesium, salinity, ph, temp, lights..
to kick off ur coralline if your water quality is as it states above you can give someone a good sized rock have them throw it in there tank and let it get covered in coralline then take it back and put it in ur tank.. ur seeding ur other rock with this rock and usually spreads quickly throughout the tank...
hopefully all this helps... im :tired: and now going to sleep...
