Hi. This is Arpi from Glendale,CA. I had a question about my tank. Its a week that I bought a special lighting for corals and I started adding corals to my tank. Alot of algae grows on my live rocka nd regular rock and I think it is because of the light which is too bright. And my water started getting cloudy and looks brown I wanna know what is the reason and what can I do to get rid of it and have clear water again. Is it because of the brown algae. There are algae on my live sand and everyday I try to get rid of it and also I put a little Kent product for my corals and maybe that's why my water started turning brown. or my filteration is not good. Please let me know what you suggest. Thank You

How much light do you have? What size tank? how much live rock do you have? What are your water Parameters, and how long has the tank been running?

cloudy water
it is a 30 gallon tank, 65 watt,10,000k/460 Nm Actinic light, i only have 1 live rock not toobig and live sand and some regular rocks with brown algae. Last time I checked the water it was perfect.

P.S. the tank has been running for a month.

Your lighting isactually quite weak. I run 750w over a 75g. Thats 10.5wpg to your 2wpg.

I'm thinking you have way to many nitrates, trites or phosphates in your tank, the Kent coral food could be the culprit. What is it exactly and how much do you feed your tank? I'm thinking that the additional lighting (if your old lighting was even smaller) is now working in hand with your excess nutrients to cause an algal bloom.

What kind of filtration are you running? It probally is excess nutrients in your tank. Try doing some water changes & possibly run some type of phosphate remover in your filter. Honestly you don't even need to worry to mush about feeding your corals. Some people don't even believe in adding food for their corals, most corals work on photosynthesis. Though your lighting is pretty low for most corals. What kind of corals do you have any way? With power compacts you should have 2 65 watt bulbs over a 30g or 1 96 watt.

tnx for the help. you guys r great

the water is clear now and i changed the water.
everything is good but as u guys said my light was weak and i think my coral is not alive anymore or i'm not sure. but it was fine for a week after i got the light and obviously i got the light first and then I got my first coral and i dont know is it because of the light or is it because of the previous cloudy water that the coral is not in a normal shape. I'll try to put the pic here and if i didn't check for the description of the coral that I will post later. Thank you[/img]

There are sp many types of coral coming in from all different areas. It would be hard to say your coral died because of a particular item unless we knew what type of coral it was.

Hi guys,
the cloudiness disappeared from my tank and when I added the "kent" for my coral, the water started changing its color to lime green. the water was cloudy 2 weeks ago and they it turned to clear gradually and after that i added kent and now my water turned lime gree. I tested my water and it was perfect. Its just the color and when i feed my fish they cant even really see the food so they can eat. its that bad and now i did 50 percent water change and I changed the filter so i hope that the water will change to clear and when i added kent to my tank I even put alittle less then it is reccomended for my 30 gallon tank. What do u guys reccommend?
