My parameters are always pretty much the same from month to month and are well within specs. My phosphates tend to get high at times. I've taken every measure in order to squash them...aint workin. The only thing I can think of is my skimmer. I skim wet and empty my cup every few days as it is really gross. The only thing I can think of is that my skimmer may not be sufficient. I also, keep a wad of poly filling in one of my baffles as a physical filtration and I replace it twice a week. Its a RO needle wheel 110. I have a 90g display and a 30g sump. I have a several small fish, not many. 2 clowns, 2 square anthias, goby & pistol, flame angel, damsel, and a banghaii card....8 small fish in a 90g. I am not sure if bumping up my skimmer to something larger if that would help. I've read in several other posts that by increasing their skimmer and or sump, it relieved their phosphates. Any ideas?

Is my skimmer sufficient?

High cap GFO in a TLF 150 reactor (changing every 3 days), fuge with chaeto....
I have healthy chaeto and a great piece of halimeda in the DT.
temp 80'
sg 1.025
calc 480
amm 0
ph 8.0
nitrite 0
nitrate 0
phosphate .41
kh 8 dkh
My MH's are on 3-4 hours a day and my T5 actinics are on about 9 hors a day. Feeding once a day with the food you gave me and some frozon plankton rinsed every other day. Could it be the poly-fil? I do change it twice a week. It does capture a ton of stuff. The HA isnt going crazy but it is keeping me very busy.

Yeah, A Reef Octopus 110...needle wheel impeller
My TDS reads 004 and no PO4. I am stumped.
Should be ok as per the manufactures specs. For what it's with I run a dnwb-110 on my 46g display with a 20g sump. It's the recirculating skimmer. And I am ordering the same one you have for my 30g frag tank with 15 gallon sump. The one I have works very well for me on my display system with tons of coral and 6 fish.
Has anyone ever heard of bumping your alkalinity to decrease HA growth? Personally, Ive never heard of it. Someone whos been in the biz for a very long time said, "if you increase your hardness or alkalinity you will pretty much stop the HA." Anyone heard of that? If so, please teach me what the chemical reason is.

I'm battling some HA too and I noticed doing my testing that my dkh jumped in the last week or two from the 7s up to 9.6. Now that might not be as high as was contemplated when you read that but I'll say that my increase was unintentional and it's had no impact on the HA. Maybe a dkh of 11-12 would be closer to what was suggested but I agree it would be bad for SPS. and here's an example where close to 10 had no impact on the HA
If the store you got your advice was in P'ville I wouldnt trust that advice.
Raising your dKH will not have any effect on hair algae - none. GAC, GFO, and lots of water changes are what most would likely recommend. If these methods fail, you may want to read up on lanthanum chloride. As mentioned above this is a nutrient issue. In terms of treating the symptoms, some have had success using Algaefix Marine. You may also want to ensure that your RO/DI is producing zero TDS. Good luck!
What type of live rock did you start the tank with Marco, Florida gulf rock, etc...?
To be honest I am not sure. I know it wasnt Marco. It was cycled well over a year ago though. Why do you ask?
Even though it's been over a year? Wow...I had no idea it could continue to leach for so long. I suppose it certainly could be the problem. But as I said earlier, it's seems to be much better and a bit more under control. Other than a little pickin here and there. As long as I run the GFO though. I am afraid to stop, in fact I dont find any reason to stop. Is there any harm in continually running GFO?
