brownish colouring on rocks and walls

[liquidnoise]

Recently we notice brownish colouring on the glass walls as well as the white corals and shels. even white stones are turning brownish. Even the snail shell certain part also turn brownish.

We notice that its the surface area tats facing the lights that shows the borwnish colouration.

Is is not very very bad but white a white stone turn brownish maybe must ask why before its too late

Brown algae??

Should be diatom bro. New tank?

[liquidnoise]

the tank have been running for slightly more 2 mths. I have been dosing Ca, Mg and Sodium

[liquidnoise]

The question will be if its is harmful? shd i be overly concern?

[liquidnoise]

Just to add, test NO3 yesterday shows 0ppm

If can be easily brush off then its diatoms.

part and parcel of a new tank, you should only be worried if it is red slime algae

[kraken]

if u can, reduce the light period or totally off your lights for two/three days (take note if u only have fishes and no LPS), all algae will be gone.

then as usual, if u are hardworking enough, use a toothbrush to brush off the algae from the rocks and do a WC 15%-20%

repeat the cleaning and reduce lighting period over the course of the next few days should see your problem vanishing sooner than you thought

[liquidnoise]

The problem will be tat I have corals....it started with me starting to dose Mg, Ca and Sodium....so i m thinking if there is a link

[liquidnoise]

color deepens. my white T5 switched on from the time we wake up till the time we sleep. which is about 8am till pass midnight. Some say its too long. Is that the reason?

[peacemaker]

These look like diatoms to me. One case is that if your tank is still fairly new, diatoms will almost certainly appear, but it will go away after some time. What are you using for your water changes? Tap water? Diatoms thrive in the pressence of silica, so if you are using tap water in your top offs or water changes, chances are, diatoms will continue to remain in your tank.

Your photopeirod is too long. You may want to consider reducing it to eight hrs.

[liquidnoise]

We use diamond water actually...the lights will reduce the number of hours. They say snails and other algae eaters are good to clear them. I have 2 in the tank i think but some say its not enought

get more cleaning crew, reduce lighting period to 8-10hrs, weekly wc, problem should go away really soon. part and parcel of a new tank setup (<6 mths old)

btw the time it shd be ready for ur blue tang? kekeke still waiting for it

Wrong lighting spectrum, extensive photoperiod, premature addition of livestock, excessive feeding, release of nutrients from poor quality liverocks (including base rock of corals), multiple reasons for excessive nutrients...<br /><br />Diatom to me, just let it ride out, cut down light, stop adding new stock, reduce feeding, use proper equipment and practice proper husbandry...<br /><br />Ur only and best solution

I have a lot of red slime algae in my sump at the refugium where my chaeto are growing. Do I need to worry?

i used to have that in the initial stage in the ref. yes you need to remove the red slime algae, else they will take over your ref, worst scenario spread to DT.

suggest you clean them off and turn off the ref lights for two/three days.

[liquidnoise]

AFter WC the situation seems beta. BTW, i also have UV running longer hours...maybe it helped. Also cut down on feed and number of hours the lights are on

[troyjbon]

For me i just scrub them off using tooth brush. They will grow again. Ive reduced lighting to only 6hrs and works great.

[liquidnoise]

so far the brown cloloring is not tat dark and in fact getting lighter by the day. brownish sand is also reduced. its a good thing i suppose, but worried if the lighting is enough for the corals.

Can you share with us what T5 lights you are using (wattage, intensity, number of tubes)? I read in your 31 May 13 post that you were dosing Ca, Mg and Na. For a new tank, I feel you should stick with water changes. Dosing can come in later. Anyway, why did you choose to dose the 3? In fact, I don't think anyone doses sodium (Na), which is essentially salt (sodium chloride). Did you make a mistake?

[liquidnoise]

we have 2 x 3ft aqua zonice lights. not sure wat wattage. 3 blue 1 white, i was advice tat these 3 element is impt so we just when ahead to iwana to buy. we do not dose 3 in go...its like 1 tiny tiny MSG spoon a wk type. for one of each of ther element. Its not sodium choride but i tink its sodium bicarbonate...to lazy to go downstairs to verify. We are going to construct a scrubber soon (i hope my dad starts). I do travel alot for work so wanna try to teach them as much as possible. Been bringing them ard to LFS hear and learn so buy n try lo. like everything in the world. try in small dose 1st. Anyways, also bought test kits to will periodically test the water to see if they are doing the rite thing

Hi bro. Have you check tds after using diamond water?
