algae issue

Everyday I have green algae on my acrylic. It wipes off very easy but it looks bad. Why am I getting this algae? Do I need a fosfate reacotor?
 
I feed one brime shrimp cube a day and I only have 3 fish in a 65 gallon. I'm running a protein skimmer and refugium and carbon.
 
Do you strain the cube juice prior to feeding? It is usually full of nasties that feed algae.

Also, what type of water do you use? Tap? RO? RO/DI? Pre-mixed?
 
no i don't strain the cube. I use RO fresh water from a glacier machine and buy my SW from the LFS.
 
only 8 hours. Now that I think about it, it might be because I have to much light. I recently just added an additional 260watts to my already 350watts for a total of 510watts. Is there anything I can do besides reducing the light?
 
A daily dose of thawed out brine shrimp cube water is loaded with phosphates that algae feeds on. Have you tested your tank's water for phosphate?

Also, how old are the light bulbs? Over time, their wavelengths change and also feed algae.
 
I'll check into that, thanks. The one halide bulb is 4 months old. ANother is about 9mo. I don't know how old the PC's are.
 
I've said it before and I'll say it again. Those Glacier machines are not always the cleanest. If you don't believe me check the water you get from the machine with a TDS meter. It will measure well just after servicing but those machines are often neglected. There's a big difference between "clean" drinking water and pure RO/DI. Glacier water is probably better than tap water but if the machine isn't maintained it might as well come from your faucet.
 
The Glacier machines will say when they were last serviced. The old ones should be marked by the tech, the new ones with the LCD on front will display the date.
 
Try leaving your lights off for a week. Sounds scary, but I did it, well, not voluntarily. Lights blew out and took a week to get replacement parts and bulbs. After that incident, the algae on my rocks aren't even growing back. My blenny switched to flake foods too...

There still made for drinking water not reef tanks.......RO membranes made for drinking water have a much less rejection rate then the membranes we use (most of us use)

Won't my corals die?
 
The trick with the lights will work, but I believe it is a temporary fix. If you have a nutrient problem your algae will be back long before your corals regain their color and health.

IMO a solid action plan would include the following:

1. Eliminate the existance of excess phosphates, nitrates, and silicates through water changes and pure RO/DI top-off water. Unless you are getting your water from UCSB or Scripps I'd avoid so-called NSW or shop-mixed water. Mixing your own water isn't that hard and assures control over the addition of anything foreign.
2. Increase skimming from dry to wet while closely monitoring your salinity. I personally remove a cup of skim per day and replenish the tank with a cup of fresh SW to compensate.
3. Change your carbon every 2 weeks. Let carbon soak in RO water first to help leach out any PO4.
4. Soak/melt any frozen food in RO water, then strain before feeding.
5. If using filter socks or pads, wash them frequently. After cleaning soak these in RO water as well.
6. If you have a sump or refugium, try a clump of Chaeto macroalgae. A cheap Home Depot lightbulb is all it takes to make this stuff grow, and it will absorb nutrients naturally. If you don't have a sump, try taking a plastic strawberry basket and suspending in the corner of your tank just below the surface of the water. Fill the basket with a loose clump of Chaeto. Remove clumps as it grows to export nutrients and to keep it growing. IMHO this stuff is the best filter I've ever come across. I run a 150g sps tank with a 20g prop tank, and my filtration is all skimmer and chaeto in my sump.
BTW, don't pay for chaeto. If you need some I'll give you a bag full as will many others on this forum. Many people I know harvest so much they end up throwing it away.
7. Probably the most important step... patience. Nothing ever goes away overnight, especially algae problems. Practice good tank husbandry and your tank will respond in time.
 
Definitely the good husbandry and responsible feeding along with other methods can help with the problem. Go through that list.
