I have a skimmer

Any ideas on why my sand is turning brown, I have 2- two spot gobies to mix it up and sift sand. I have healthy growth of my corals and I do WCs every week . I use RO/DI water and reef salt in my mix and RO/DI with kalk for ATO.

Extra oic

How deep is your sand bed? How many gallons is your tank... I think you do have a slight dead spot over there. Have you got any turbo snails in there?

 

[Tonynose188]

29g jbj with hob skimmer / refugium. Sand bed is in the front about 1/2 inch. I have 3 turbos 2 2 spot gobies as well

Should I increase flow by lowing one of my power head?

 

[Tonynose188]

Just took this this morning so my gobies must have been up all night haha but should I increase flow?

 

[Craigj247]

I think you should increase the flow and maybe get more snails... General calculation is one turbo per every gallon of water. How long are your light on daily?

 

[Craigj247]

You could also try some pincushion urchins... Good algae eaters... But I think it looks good all in all nothing to really worry about. How often do you do your water changes and what is the quantity?

 

[Tonynose188]

10% water changes every week. That algae gets deeper in color as the day goes on with the lights I am guessing (LED).

 

[Tonynose188]

Sorry I have the day lights on from 1130am-830pm

 

[Craigj247]

Hmmm try cutting down on the lights that should help... I generally get the actinics on by 7 and then the whites on by 9 and then the whites go off by 6 and the actinics are off by 8.30 or nine... I still think the algae issue you have is not too bad you can also try 15-20% changes and don't forget to get a few extra turbos... It should clear up...

 

[Tonynose188]

Do the Arctic lights cause algae growth? Should I do daylight-Arctic-off for a daily setup

 

[Craigj247]

Well if you have your lights on for too long on a daily basis it will promote algae bloom... But don't knock the actinics off at any point during 7 to 8 cause of you only run your white lights without the actinics you won't get the proper colour temperature for your corals to grow...
