    I know that this is likely talked about ad nauseum in other threads on here, but (instead of searching everywhere, because lazy) I wanted to see where everyone is currently keeping their phosphate ranges at. I just checked mine for the first time god knows how long and it's at 0.19. I'm...

    Hi Guys, Tried Vodka dosing for the first time recently. I'd been feeding liberally in my very small 12" cube reef thinking that my nitrates where all being cycled. However, I got a very large shock when I tested them and found they were 50ppm. A discolouring SPS alerted me. I've never had a...

    I am having a problem with algae in my 90 gallon reef. The algae is a dark brown, stringy kinda looks like a spiderweb almost on the rock. I've added a phoshate reactor and my skimmer is working well. Ideas? Thanks

However, I have been having an issue with phosphates being left in the RO/DI water. I used an API test kit to check the level and there seems to be about .25...

    I have a 90 gallon tank and am upgrading to a 180. I see many people saying that moving the sand to the new tank can cause die off. The idea of phosphates increasing from moving the sand makes me curious. I clean my sandbed weekly and don't see if it is cleaned often how this is going to...
