Algae

[jackal]

Why is sandbed infested with brown algae? I tried phrosphate remover, change water regularly, suck out the affected sand n decrease my feeding.

N03 is about 30-40ppm, SG 1.025, Ph 8.5, dKH 7, CA 430ppm, MG 1230ppm.

Blue Light 11hrs, MH 6hrs.

Other corals and fishes doing well.

Plse give advice. Thank you

i also have this problem...sigh..

dun know what happen also.

[keithtanbb]

my solution, get reef helpers

1) black sea cucumber, turbo snails, blue legged hermit crabs

2) divert your water flow to "blow" gently on your sand bed without disturbing your corals!!

3) if you are using tap water for your salt mix, use a filteration....R/O is best ( I am using 3 cannister filters to exclude silicates and some phosphates

could it be the lightings? mine oso lik tat ..... but some area which is not directly under the lights dun seems to have much of the brown thingy

[AMDer]

i bought a watchman goby and it eats and spits out sand, so now not so bad.very fun to watch. like construction worker like that. haha.

but my glass sometimes got this brown thing also. have to use those magnetic cleaner to swipe here and there..sianz..

my PO4 measurement is 0 leh.

[cyberpig]

Get some tangs... they will nib the brown algae off the glass and in the process leave a lot of lips mark.. very cute like they're "muacking" you

[blueheaven]

You might have a problem with your tank silicate levels

[asg]

hi hi is the water flow (wave) strong enough? i normally see this when there is slow flow of water...

[hammy]

phosphate, silicate and nitrate lor ..

fertilizer for pasky algae.

increase the flow.

some turbo snail may help

[jackal]

Wave water flow no problem,strong enough. Cant blow towards the sand cuz tank will be cloudy wz sand. Got 1 sea cucumber n 2 turbo sails doing OT.

Dont hv silicate test kit. If that the problem,what the solution???

Glass also got it growing. Mayb its the light.

What is cannister filter tat help to exclude silicates and some phosphates? Name brands and where to get. I got a water treatment system but is for drinking.

Plse give more help

[blueheaven]

You can lower silicate levels by doing regular water changes with DI water and running silicate absorbing media.

If all goes well, the diatoms will deplete the silicate levels in your tank and then die off.

[jackal]

Any example of silicate absorbing media? 3 pails water change every 2 weeks, but I use tap water instead of DI.

[jackal]

Take a look at my tank.

Hope u enjoy it

Happy couple!!!!

Not sure if i remember correctly. The sand turns brown due to bacteria activity. As to y it happens can't really remember.

My sand was like that in the initial stages but after that it becomes less n less.

I think the best sand shifters to get is the sand stars. grey in colour.

Really hard working. Won't shift yr rocks.

hi, blueheaven,

what do u mean by silicate absorbing media?

i have a Skimz FR running with SORB-4. does that mean i need another FR to run the silicate absorbing media or can i dump the silicate absorbing media together with current SORB-4?

thanks.

my tank used to have quite a bit of diatoms. they slowly disappeared, though they still appear on the glass and sand.. but still bearable la.

anyway now i got even more pesky green algae growth. those type that very hard to come off one.

any suggestions as to how to rid them? or prevent their growth???

[keithtanbb]

Nice ! jackal....I get those green algae growth at my water edge, I scrape those , I ran a refugium full of chaeto's and some grapes, and a rowaphos fluidised reactor...guess it is the light and my over feeding conditons that promote such growth.My starfishes and turbo snails seems to enjoy them though...so I left it as it is! In my refugium I find that allowing it to run without my hands disturbing them , the macro algaes grows nicely!!!

got a weird qns here. does snails eat coralline aglae? i don't think so right?

Wow! Nice Anemone and Pair Clown

Ok here's what I think:

1) Your NO3 a tad high... although nothing to do with your current problem... try to bring it down to <10ppm

2) dKH also a tad low

3) Magnesium is nice!!! Haiz... mine very sad lor... that's why I need a CR soon.

4) If you are using TAP WATER (just like me, although I used domestic water filter)... dun thing changing water regularly will help much... coz in the process we are introducing back the depleted nutrients and silicate... to feed the algaes

5) Some Silicate removing media is good... I am also planning to run some... at least to remove the silicate from the freshwater bucket (for top up and salt mixing). Any particular brand to go for? IS it healthy to run it 24/7 in the main tank just like Rowaphos/Activated Carbon?

Bros with experience... appreciate your help and recommendations.

I think lighting plays a strong part in algae! For my tank, even though NO3 and PO4 is almost undectectable, I can still see algae forming on the tank walls and LR!

Juz my 2 cents!

[remus]

i trying to get some Nassarius Snails do anyone know anywhere has this.
