  • Hi,
    I'm trying to ID what's growing in my frag tank. I have some pictures, but I'm waiting for my microscope camera to show this week. Can you help me ID this stuff? or direct me to someone who might be able to?

    Thanks,
    Jeremy
    Hey boomer. Just a quick question, I see your comments popping up here and there on my search for a lesser expensive GAC, Basically trying to cut out the middle man. I have used BRS Rox 0.8, now have the Vertex Rox 0.8. So i started searching out the ROX and came across the Norit Rox 0.8, Do you know if they are the manufacturer, or if that product is the same stuff?

    Thanks for you time!

    Boomer,
    Could you look at the last few posts in the CA 101 thread and commetn on carbon amount and time span?

    10. Read what is in the food and look for things low in phosphates.

    11. Keep the pH in the very low 8's or very high 7's, as Cyano will out compete other algae's in higher pH water.

    12. The # 1 limiting nutrient for Cyano is N, not P based on studies in various microbiology texts.

    13. During these water changes and blowing stuff off and siphoning it up run a Diatom filter with a second cake of PAC (Powdered activated carbon).

    14. Increase water flow where Cyano are growing, as they do not like high currents.

    15. Shutting of all lights, almost total darkness for 48 hr. every few days.

    Last resort is Chemi-Clean by Boyd."
    My scheme I told you about for Cyano

    A 2- 3 month scheme

    1. Water changes. 25% weekly.

    2. Bare bottom refugium only for cheato nutrient export and not for critters.

    3. Siphon, sump, refugium, etc. every week during water change and clean all filter you have.

    4. Blow off all the Cyano and settled stuff you can so it can be siphoned off.

    5. Clean out skimmer and cup every week.

    6. Carbon, 1 cup per 50 gallons / 2 wks. Try to use ROX

    7. GFO -HC , change every month.

    8. Purigen, every month

    9. Soak frozen food in RO/DI and discard water before use. This is especially true for brine shrimp. Matter of fact I use to pour off the water, and then fill it back up, to repeat it until there was only whole brine shrimp in the container.
    Carbonate bottoms are a sink of PO4, Phosphate, as phosphates love to attach to carbonates. Cyano can "feed" off these carbonates and extract PO4, Phospahte or Phosphate organic molecules that have settled out. So, the Cyano and even the diatoms have no competition for food and growth/density populations rise. One of the key at lowering unwanted nuisance algae is to reduce that competition for nutrients/food.

    How big is the sock in microns ? It should at least 2 microns. Diatom are from 2 - 200 microns. But a few can get as large as 2 mm. Diatoms like to live in water with high silica. But they are no different and still may be there if the silica shows zero.

    I forgot yesterday I think. You have very high NO3- for a reef tank. I think you said like 20 ppm. No good as that tells me two things. It is fueling the Cyano/diatoms and is an indication of poor water quality, tank maintenance and over feeding and that refugium is not doing its job. When there are few animals in the tank they are not "feed" things falling out of the water column. The # 1 nutrient limiter for Cyano is N ( NO3, N, NH3) and not P ( Inorganic or Organic Phosphates). And you have sit loads of N as NO3-
    hey Bill Bill her, thank you for taking the time with me on the phone, i appreciate it.
    question,
    can i suck the diatoms into my sump filter sock or will it pass through the sock.

    Oh where oh where has my buddy gone. Oh where oh where can he be ?
    Probably still down in Tehas. :D
