  • some dosing guidance please...

    been a while since I posted, sometimes you just get burned out and need a break, work is really busy and I'm trying not to mess with the tank to much.. anyway, my tank has been doing so-so.. I dosed interceptor a few times a in Jan and once in Feb and I think I may have suffered a mini-cycle after that, I'm getting some macro growth and patches of bubble algae that just keep getting bigger. seems to have gone in cycles the last few months, algae starts to grow and then starts to die off a bit, then comes back again.. I have 2 little patches of HA also, one on the front glass at the bottom, and another in one of the back corners of the tank. I syphon it out and it just keeps coming back, not at plague proportions but enough to look ugly..

    Tank is 30gal, total water volume around 40gal. I use 1 cup zeovit - cycled 3on/3off, 1/3cup carbon. I recently swapped out the reactor pump from a [email protected]' eheim to a rio-400 ([email protected]') as it appeared there was not quite enough flow through the rector..

    now for the dosing story... I was dosing 1 drop bak/1 drop food EOD, 1 drop start 2x/day (less if there is algae on the glass), following the dosing guidelines I dropped back to 2x/week after 2weeks of new media, and I just wasn't seeing the zeolove in the tank.. so I've been watching things and dosing 1 drop bak/ 1 drop food every day, along with the start.. I check to see if there is any tissue loss at the base/tips and I check for colour before dosing but so far nothing more drastic than a little brown fading.. my a.valida that was coloring up decided to stop and go all pale on me again...

    The bottle of bak I have is past 6 months and has fuzzy lumps, but there is no smell coming from the bottle..

    One thing to note, although how relevant it is remains to be seen, the ORP reading was around 330-350mv when I was dosing 2x/week, now that I've upped the dose it sits around 420mv..

    I saw a post from Madison (and now I can't find it) with dosing for his frag tank, my tank is the same size, and it seemed a lot higher than what I have been dosing.

    so, on to the question... which is better, more less often, or less more often when it comes to bak/food. I'm thinking of doubling the dosage but wondered if I should still dose bak ED or EOD until I find the right amount.. I have been in phase 1 for the last 8 months it seems, either that I just flip flop from phase 1 to 2 and back to 1 again. Last time I measured PO4 a few weeks ago it was up at 0.07, I had it down at 0.04 in October last year (was 0.06 in Sept 2004), but I don't seem to be able to get down near that any more, and I find it to depressing to test PO4 on a regular basis.

    this tank has no fish and gets no food, LR gets blasted every couple of days, 100micron filter sock changed weekly and 10% WC weekly - haven't missed one yet. RO/DI TDS 0, and Oceanic salt.

    any and all dosing advice appreciated.

    Hi Rich, good to have you here Can you give a description of your corals--light or dark? Appearance of the tips--any tip lightening, thinning or recession? Can you give us current parameters of your reef, along with nutrients levels? Thnx. Bob

      thanks Bob. I am getting some lightening of tissue all over, from the tip down. most appear to be pale.. no tissue recession that I can see on the tips or base.

      tank parameters are:
      Alk - 7
      Ca - 420
      Mg - 1250
      SG - 1.026

      I knew you were going to ask for PO4 and I was dreading testing it..

      PO4 - 0.17

      thanks,
      rich.

        Here is the link you were referring to. However, I am using ZEOstart2 which you can and should use more than you would with the original ZEOstart.

        If you haven't already, I would hold all zeo dosing for 5-7 days until recessesion stops.

          Thanks for the link Madison.. are your dosage amounts for ED, EOD, or 2x/week ?

          where does one purchase ZEOstart2 ? I just checked captiveoceans.com, and pieceofreef.com and neither site has it listed (that I could find)..

          I originally just listed dosing amounts for the basic 4, I have also been dosing the following:
          HCAA - 1 drop / day
          PIF - 1 drop / 2x/week
          occasional FE use - 1/2ml / 1x/week - has not been dosed in at least 3 weeks.

          thanks,
          rich.

            Rich, I am dosing the ZEOstart2 everyday. I dose the bac/food twice a week.

            The 'start2 will be available for order tonight or tomorrow if the UPS guy shows up

              Hi Rich, we have a problem P04.17 is very high Plz. check your product water TDS. Without fish or nutrient import[assuming no addition of uncured, or "bad" LR] either your source water is high in chloramines, damaging the RODI membrane, with leaching back into the product water, or your zeo-filter flow is not correct--it must be <50gph. Plz. measure this, as if these are the problem & go undetected, one will never reduce the nutrients, improve color, etc.
              Madison's dosing schedule is fine & I recommend following his advise if the two aforementioned possible problem areas are resolved to your satisfaction Bob

                Thanks Bob, I just checked my last batch of RO/DI and it still reads 0 TDS, tap water is 426 TDS. reactor flow may be the issue tho.

                no additional LR has been added.

                how do I measure flow through an open top in sump reactor ? My reactor is 3" x 3" (square) and comes up 7" out of the water so I'm not sure what that means in terms of head loss to a pump.

                is it better to err on the low side for reactor flow ? I might pull the rio off and put an 80gph pump I have on it for now.

                thanks,
                rich.

                  Hi Rich, the Eheim 80gph with the head involved should be about right. A little more is fine. Madison & I have discussed Start2 dosing abit, so either one of us can help when you receive it---and plz. use it, it's that good Bob

                    thanks Bob, the pump has been swapped back. I only changed it out when the stones were last changed (5 weeks ago) becasue of the macro growing. I somehow managed to convince myself it wasn't enough flow.

                    I'm still unsure how much and how often I should be dosing bak & food. These stones are 5 weeks old now and I have been dosing around 4x/week 1 drop each bak and food. should I increase the dosage to 2 drops and lower the frequency to 2x/week, or just stick with 1 drop EOD, or go back to 1 drop 2x/week ?

                      ok, I will follow Madison's dosing schedule for now, switch to start2 when Madison has some in stock, and keep an eye on things for now.

                      I'll also test my next batch of WC water for PO4 to see if there is anything there.

                      The other possible source of PO4 is the CaRx media (crushed coral). I soaked it in RO/DI for a couple of weeks before use, changing it's water a couple of times. Maybe it's worth changing media in the Rx ? or adding a biophos Rx ?

                        Rich I was going to bring up the reactor thing also. It's hard to test the open top kind but if possible, here's how to do it. If you can have the pump in one resevoir water, and have the reactor in another res (bucket or tray) and mark where 1 gallon fills to on the bucket. Then turn on the pump and time (from the time water overflows the reactor) how long it takes to fill one gallon. then divide that number into 3600. This is your GPH. I suggest using short storage tubs/trays as to not interfere with extra head pressure created by a tall bucket.

                          Rich, did you check your Ca Rx's effluent for P04? If it is higher than the system's level, then a BioPhos reservior will be needed. Bob

                            The Ca Rx was guilty of polluting the water so a BioPhos 3 reactor has been added along with 1/4 cup of media..

                            I started dosing ZEOstart2 today. I was going to try 2 drops in the morning, 1 mid-day and 2 in the pm and see what happens...

                            thanks for the help with this little PO4 addiction I have..
