Thanks everyone for pitching in with your insights for my frustrating situation.
My nitrates are reading below 10, and I have to pick up a phosphate test kit (though I use 1 Phos-Zorb in my cannister filter, and replace the pack every 3-4 weeks with my 2 carbon packs).
My lights (50/50 and 10,000 degree K
bulbs) are about 5-6 months old, and operate 9 hours a day.
My aquarium water isn't a different color but just appears a slight bit cloudy, meaning it isn't crystal clear like it should be. I rinsed off some of my dead/frozen coral pieces which had brown and green algae, and the rinseoff water was brown, which is why I feel the algae is the cause of my clarity issue.
I only have 2 water sources in my apt., being my bathroom and kitchen. At this time, I don't think I can set up an RO
anywhere, and honestly, they seem a bit complicated to install and maintain. Is there anything else on the market that can filter out silicates? I'm 99% sure now that this is the cause of my problem (silicates in the tap water used for PWC
Also on a side, and though this may sound silly or ridiculous, I read somewhere that drinking RO
water is not recommended as many minerals are filtered out which the body needs. Another reason I hesitate to have one installed.
