    skimmer mod - need advice

    Here are some pictures of a MAG12 I modded with a home made needle wheel for a DIY skimmer I built. I did go back and add twice the number of "needles" from the pictures. What I did is cut the propellers off the MAG prop and put it in a drill press shaving the prop down to accept a 1/2" piece...

    ?? re: Alk/Hardness tests

    At this point your Ca reactor isn't doing anything but hindering, so I would turn it off. Once your alk comes back, turn it on slowly until you find a balance. Keep dosing with Ca chloride.

    Porcupine Puffer question

    Another method, after cleaning the clam, is to take a hammer to the clam. This will break the shell up in to pieces and the puffer will chew on the shell fragments eating the clam off them and spitting the pieces out. This helps assist in keeping their teeth trimmed.

    I can not find any details on that salt from the studies. I know Eric Borneman and Kim Lowe's study is supposed to be released soon -- haven't seen details yet.

    ?? re: Alk/Hardness tests

    A couple things - here is a link to a calculator that should help you determine how much Ca additive you will need to add. Keep in mind that precipitating calcium carbonate which will consume some and be sure to read what the calculator page says. There are a few sites that have the initial...

    ?? re: Alk/Hardness tests

    Do as Don stated and get another Alk test to make sure that your results are accurate (Alk off the chart). Also, make sure the Salifert lot #'s are different and the expiration date (yellow sticker on box) is the newest possible. This is all on the assumption that your Alk is high -- please...

    ?? re: Alk/Hardness tests

    There have been a lot of reports of issues with the Salifert Alk test. I too had problems with one of my kits. See this thread on RC http://www.reefcentral.com/forums/showthread.php?s=&threadid=1117617

    Changing salts

    As NaH2O said, your RO/DI water should be stripped of everything and your pH should be neutral (7.0) and as the article states it can change based on CO2 over time. Aeration and water movement should increase the pH over time - I do this will all my buckets. Do you have a TDS meter hooked up...

    Changing salts

    Typically salt has all of the parameters pretty close to where they should be. Having said that, if buffering and adding salt brings everything where it should be, then ok. Now, if the Ca is low in your make up water, than you can add Turbo Calcium to bring that in line, just be conscious of...

    Changing salts

    Please be careful when using Super Buffer. It can, and will, get you in a corner. When you are adding to jack up the pH in the tank, it is also having an affect on Alk, among others. If you get your Alk too high, you will then start affecting your Calcium in a negative way (which is what I am...

    How do you clean filter socks?

    Mine pill when I use the washing machine, so I do it manually now. I turn it inside out and scrub with hot water.

    Cal And Alk High

    I, like others in the thread, are not saying to go get a Ca Reactor now but this article helps generalize the setup and understanding of how a Ca Reactor works.

    Deep Sand Bed

    I, personally, think a 29-gallon's footprint would be too small for a RDSB and not sure if you would gain the benefits for a 125-gallon tank.

    Wowa - (2) #3's in a 40 is going to be pretty intense water movement. I have (2) #3's in my 180-gal puffer tank. If the Porc is not paying attention he has been thrown half way across the tank from this ph. Just wanted to warn you if you haven't seen these in action.

    Deep Sand Bed

    I totally agree with NaH2O - adding a DSB could have its pros, but with such a new system, I would get it stable and understand why a change is needed. In my previous 72-gallon I put a DSB in the tank right off the bat and can not imagine trying to add it after the fact. When I upgraded to the...

    Changing salts

    There has been some research on which salt is best, blah, blah. The documented test results from Eric Borneman's study should be released soon, but it has been so long since he did the study I am not sure how much it will hold up anymore. I, along with most of reefing community, use IO. In my...

    Testing with inconsistent results

    Hey trillyen. I have seen quite a few people that say they never test anything and yes, some are just that good, I guess. There are so many variables that I can not imagine never testing anything. When everything is cranking in my system I go a while without checking certain components, but I...

    Aquarium Chiller recommendation

    Try this place - they make chillers for lobster tanks, etc. - http://www.frigidunits.com, then click on Products and Chillers. There first unit cools at 35 to 70deg. F.

    koralia powerheads

    The one other issue I have is the magnet isn't quite as powerful as I would like them to be. I have a 180-gallon Glass Cages tank and the glass width is the "max" that they recommend, but mine just barely stay on. I wanted to mount them on the back of my tank, but I painted the back with...

    Acropora bleach from bottom up

    Very cool link - thanks. I hadn't bumped into that one before. Yes, correct, pH isn't part of the Ca/Alk relationship, but the Alk or TA (Total Alkalinity) affects pH. Trust me, I am not trying to teach you anything you don't know, just explaining why I had pH in the mix.
