SRC Member beaver Posted June 13, 2006 SRC Member Share Posted June 13, 2006 Halo, As above, just wondering why there are brown algae on live rocks and branches, even phospate is near zero? None on the sandbed and glass. I don't even switch on the actinic lights very long daily. Thanks! Quote Link to comment Share on other sites More sharing options...
SRC Member aquabeAnz Posted June 13, 2006 SRC Member Share Posted June 13, 2006 PO4 test kits only measure the inorganic PO4 present in the tank..

SRC Member aquabeAnz Posted June 13, 2006 SRC Member Share Posted June 13, 2006 brown algae on live rocks and branches Indo LRs have quite a bit of PO4 leeching out in general Quote That just because someone doesn’t love you the way you want them to, doesn’t mean they don’t love you with all they have.

SRC Member beaver Posted June 13, 2006 Author SRC Member Share Posted June 13, 2006 brown algae , if diatoms usually caused by silicates So how do I get rid of it? Thks. Quote Link to comment Share on other sites More sharing options...
blueheaven Posted June 15, 2006 Share Posted June 15, 2006 Use those phosphate/sillicate removal media and top up with at least DI water. Diatoms build a sillica shell around their cell and that's why they need sillicates to thrive. Hope this helps Quote But if you tame me, we shall need each other.

SRC Member shoelevy Posted June 15, 2006 SRC Member Share Posted June 15, 2006 it can also help to increase the flow in your tank simply by installing a good wave maker like tunze or seio. actually, most reefers i know who are keeping sps still have such algae growing but its not an outbreak. as long as yours isn't an outbreak and its just slow growth in certain small areas, then just let it be Quote Link to comment Share on other sites More sharing options...
SRC Member beaver Posted June 15, 2006 Author SRC Member Share Posted June 15, 2006 Thanks all! i am currently using Rowaphos. It is not really an outbreak lah but the brownish tinge makes the rocks look dirty & i am worried that they may reduce coralline algae growth. I don't use DI water but tap water treated with Kent Marine Ammonia eliminator..... Quote Link to comment Share on other sites More sharing options...
blueheaven Posted June 16, 2006 Share Posted June 16, 2006 Rowa should be able to reduce silicates to some extent but I think that bulk of it still comes from the water we top up. But just to sidetrack a bit, do you guys know that diatoms cannot live in the wild without water currents? Their silica shell is so heavy that if there is no water movement, they'll sink to the dark depths and die because there is no light Quote But if you tame me, we shall need each other.

keithtanbb Posted June 17, 2006 Share Posted June 17, 2006 hey beaver, do you have good current over that area that the diatom are growing on? I experience some growth in the "dead" area as the diatom/algae are free to propagate! installing a small pump over the area to provide some current may help Quote Link to comment Share on other sites More sharing options...
SRC Member beaver Posted June 17, 2006 Author SRC Member Share Posted June 17, 2006 Thanks guys! I have a powerhead in the tank liao. I would add another one later today..... Quote Link to comment Share on other sites More sharing options...
