In need of some algae help!

Rate this Entry
Earlier in the week I posted a request for an algae ID and i'm reaching out again for more help. I have been siphoning out algae for the last two weeks and it seems that although my problem has gotten better, it always seems to return just as quickly. Tested all of the water parameters and as far as I can tell the tank is testing within all parameters I tested.
Currently my tank is experiencing what I believe are nitrogen bubbles across the rockwork. While the tank has been running for over a year, I experienced a devastating cycle about 2 months ago that practically leveled the tanks inhabitant. This occured after attempting to use chemi-clean to rid some red slime and what I believe was a nitrate spike that spiraled out of control. <--- (Yes I airated the tank with an air stone , and no i'm not blaming the chemi-clean).
Had a few questions I need some answers to:

1) I started biopellets about 2 weeks ago and i'm wondering if I should still run GFO until they take full effect to help quell some new algae growth.

2) Would a lights out period do any good or stress my SPS out too much and kill them <---(Really don't want this)

3) My cleanup crew is a bit light due to the tank cycling and wiping many of them out. Has anyone had any experience with limpets or chitons and their ability to clean rocks? My hermit crabs have slowly been killing one another and eating any snails they can turn over so I would rather stray from them.

4) Any other ideas?

Thanks for the help!

    Hey JABlacher, just wanted to tell you: if you have a bubble coral watch out if you do a three day lights out. When I did one my bubble coral totally died. When I turned the lights back on I was disappointed. Just a warning for ya.

    I would remove the GFO since you are running biopellets. What is the PO4 level currently?

    Why do you want to run lights out? Because the cyano bacteria is back? Can you siphon out most of it? Blow off the rocks and corals with a small powerhead or turkey baster to get it into suspension. If you have a filter sock, catch that stuff as the drainline pours into the sump. Keep your skimmer & neck clean so it can work optimally.

    Get more snails. I would rely on chitons and limpets. They are too small to consume algae on a regular basis. I rarely see either actually near nuisance algae.

    Testing the tank with a Hanna phosphate meter tested 0 ppm. I'm only assuming that the algae in the tank is consuming what phosphate is in the water throwing off the test.

    Besides the small managable amount of cyano that recently started ( I'm assuming because of the bio pellets?), Im dealing with what I believe are branching diatoms. Small stringy brown algae that covers the rocks and some of the bases of my hard corals starting at the frag plugs. I'm only assuming thats what it is based on pictures I have seen. I've read that possibly cutting the lights might help but this is my first experience dealing with this.

    Been siphoning this every few days as it appears but it just seems to come right back. Now my mixed salt water tested .07 ppm of phosphates. I'm draining the water from my 55 gallon mixing container to clean it. Going to mix some water and test it to see if the container might possibly be leaching phosphates. The source water from my RO system tested 0 so I just need to rule out the trashcan. Im figuring that with my weekly water changes adding a fresh batch of phosphate to the water column I'm simply making the problem worse with every batch.

    It could be the salt too.

    Double check if it matches dinoflagellates. I had some in my reef a few months ago, but I resolved it with hydrogen peroxide. I have a blog on that; use the Advanced Search to find that entry.

    Going to check out the blog on dino as that was another one of my suspicions.

    Have a hard time believing it could be the salt as I know others who are using it with great success. Not going to rule out a bad batch at all though. Been having good success prior with the red sea coral pro but i'll know a bit more after ruling out the trashcan as a source of the problem.

    Just for reference melev, what salt have you been using?

    Just finished reading through a 33 page post on reef2reef on the peroxide dosing as well as your blog on here and numerous other articles on dinoflagellates. My tanks algae has had all of the symptoms of Dino no matter how much I wanted to deny it.

    Couple questions on the hydrogen peroxide dosing:

    Did you use the 1ml per 10 gallons dosage?

    Many also reported combining that with a lights out period but not sure if that was necessary. Did you do this and when during the day would you dose?

    Did you have any I'll effects?

    How many days did you dose?

    Thanks for the help!!!!

    I've used a few versions over the years (I.O. , Kent, Oceanic, & Red Sea), but with this tank I've been using Sybon Reef salt. Premium Aquatics carries it. If you didn't have that choice, it would be Kent or Red Sea.

    Yes, I put in 30ml of peroxide in my system with a total true water volume of 300g. I dosed for 8 days. My lights were on as usual, and each day the dinos lessened in volume on my corals. By the final day, I didn't see any anywhere. None of my livestock seemed affected.

    I dosed into the skimmer section of my sump to give it time to dissipate.
