<span style="color: #000000"><span style="font-family: Arial">There are also some animals you can use to fight hair algae, such as Mexican Turbo snails, sea hares, and tangs.</span></span>
<span style="color: #000000"><span style="font-family: Arial">There is the rare case where you can do all of the above for a long period and even then not be able to control hair algae, because you probably have phosphates coming from your rock. I have only seen one case that this is probably the cause of in the whole time I have been an ARC Member, and that looked to be the case with Hanin's tank, as he could not get rid of his algae for the life of him, and he knows what he is doing and is a very experienced Reefer.</span></span>
<span style="color: #000000"><span style="font-family: Arial">Thank you for the id, as I’ve never been 100% sure what it was. Sorry in advance if I am hijacking this thread. Here’s my story. I don’t know for sure that I know what I’m doing but I have put a heck of lot of time into trying to figure this out.</span></span>
<span style="color: #000000"><span style="font-family: Arial">Background</span></span>
<span style="color: #000000"><span style="font-family: Arial">The tank was started in March 2010 and ran pretty good for about a year until roughly February 2011 which is when I had my first child. I performed good maintenance until this time pretty close to what I am doing now (see below). After February 2011 my priorities changed to my new child and I did not keep up with maintenance and pretty much just did top-offs and cleaned the skimmer until roughly August of 2011. By this time I had severe green hair algae everywhere and I made a commitment to change. I have since followed the regiment below very strictly. I have also seen improvement, it’s just painfully slow.</span></span>
<span style="color: #000000"><span style="font-family: Arial">Water Changes -- My RO system is in the basement and I do not like carrying 5 gallons of water upstairs. Due to this I change 2 gallons per day, roughly 2% total volume. I have done this strictly since August 2011 meaning 9 out of 10 days no exceptions. Recently, in the last 3 weeks I have cut this back to 2% every other day as I’m wondering if I’m changing it too much.</span></span>
<span style="color: #000000"><span style="font-family: Arial">Feeding -- I absolutely have not overfed since August 2011. I admit I used to, but since August, I feed frozen once per week and dry once per day, about 8 very small pellets per day. My fish eat it in less then 10 seconds. </span></span>
<span style="color: #000000"><span style="font-family: Arial">Skimmer -- My skimmer sucks, is a super skimmer and I have to tinker with it constantly. I probably average 1 cup of dark skimmate every 3 or 4 days. </span></span>
<span style="color: #000000"><span style="font-family: Arial">GFO -- I have run GFO since August. I have increased the frequency of how often I change it from starting at 1 month, then 2 Weeks, then 1 Week, and for the last 2 weeks every other day. I also have been regenerating GFO for the last 2 weeks, still evaluating if regenerating is working.</span></span>
<span style="color: #000000"><span style="font-family: Arial">Lights -- I have an Aquatic Life 4 Bulb 48” T5 Light. I’m currently running 3 ATI Blue + and 1 ATI Purple +. All bulbs are about 2 months old.</span></span>
<span style="color: #000000"><span style="font-family: Arial">Here is a link to my parameters for anyone that’s interested. Basically, Nitrates have always been extremely low, and Phosphates always creep up on me after within a week of changing GFO. </span></span>https://docs.google.com/spreadsheet/ccc?key=0AoVt_KiBbaUXdDA3bVNNRW80VXctTkFmdzRyMGNHaXc"><span style="color: #1155cc"><span style="font-family: Arial"><u>https://docs.google.com/spreadsheet/ccc?key=0AoVt_KiBbaUXdDA3bVNNRW80VXctTkFmdzRyMGNHaXc</u></span></span></a>
<span style="color: #000000"><span style="font-family: Arial">For a while I thought it was my RO system and I have added a second DI chamber and tested the RO phosphates consistently at .06 or so. I tested a bucket of new salt water and came up with .15, which I gathered from reef central was not that high. I am noticing small improvements, but it’s been a very slow process. I currently believe that I may have saturated my rock with phosphates and I’m going to have to continue with GFO until they are depleted. I cooked one of my rocks for about 1 month and a half then tested phosphates at .2. I then started dosing phosfree to that and got the phosphates down in 2 weeks. That rock is currently in my QT since it still had some aiptaisia left on it and I have some Pep. shrimp in my QT. I’m cooking another rock, but this is also a very slow process. </span></span>
<span style="color: #000000"><span style="font-family: Arial">One other note, I’ve tried several batches of snails and they never seem to do well in my system. Not sure but they usually only last a couple weeks. I recently added a lawnmower blenny and he is helping. I also have a yellow tang that pics at it quite a bit and helps too.</span></span>
<span style="color: #000000"><span style="font-family: Arial">Sorry again for the long post.</span></span>
