    Refinishing Hardwood Floors

    4 hours of no skimmer is not going to kill you. However, the gas exchange from the pumps and surface is still significant. If it is a nice day, 20" box fans in windows will move a lot of air in and out, and are not expensive. Of course, it will be 5 degrees, like you said.

    Free Skimmers

    They have some nice coral up there, too. I went a few weeks ago to get a free tank and got a few pieces.

    Refinishing Hardwood Floors

    I use Rubio and Osmo on an almost-daily basis and they are great. Both are just a blend of waxes and oils. The best thing about them is that if you get damage or want to refinish, you just have to do that one area and not the whole floor. You can literally just lightly sand one square foot in...

    3 - 250 W DE MH Pendants with LED moonlight.

    Kind will help too. Maybe some photos. There are plenty of MH users in Colorado.

    WaterBox 220.6 The 2023 Rebuild

    You can put dolomite into your CaRx if you do happen to need more magnesium. I never really have need to dose magneisum, either with the old ARM, the new ARM or even the Reborn when you could still get it. I only ever needed dolomite when I tried man made reactor media from Aquamedic, but that...

    Any Cabinet/Granite Folks

    Need a 36" cabinet removed from our island and granite cut to accommodate a new 36" range. Anybody have the time for this job? I am in Longmont. I have cash.

    Calling all RO masters

    First, do you live in a part of town that has chloramines? If not, then this is easier. If so, then it is important that you know and have a plan. Generally speaking, production and efficiency do not go hand in hand. 99% membranes with very little waste are available, but very low output...

    Carbon dosing via pellets

    You are almost certainly iron deficient. Dosing will help the chaeto grow. I know of no other reason to worry about low iron unless macro is growth limited. Your no3 is likely low because of anoxic bacteria using the oxygen and turning the no3 into nitrogen gas - this is the final step in the...

    Using DOS for CaRx

    It is a more reliable maxi-jet that has an adapter that fits RO tubing easily. They don't last forever, but I get 3-5 years out of them for $20-30 a pop.

    Carbon dosing via pellets

    Water changes mostly, but Ferrion for a supplement. Chaeto Gro is a product that is newer on the market. Remember that high tide lifts all ships. Iron can help hair and other types of algaes grow too.

    Using DOS for CaRx

    Buy a quiet one 1200. There is a fitting in the box where you can slide in ice-maker or RO sized line, or you can use 2 part putty to make a fitting. This will work for quite some time and it is cheap and easy and you won't ruin a more expensive DOS by using it continuously. You will need a...

    Craigars 975 gallon system

    29 dKh is solid output number. Unless you have like a MaxiJet on full blast with no ball or gate valve, then the reactor will produce more. Coralline is likely your biggest consumer - you can use pincushions to keep it down 6x18 is not that big, but it should get you more. Maybe you have a...

    Craigars 975 gallon system

    You might even be running it too fast. Who knows. Test the dKh and let us know.

    Craigars 975 gallon system

    Unless your CaRx is really small, it should be able to keep up if it has a good tune and you are not trying to "control" it with a pH probe. Some people have no interest in this, but if you do, let me know and I can show you how. Even my 4" body and 30" tall Korallin could handle a 10,000...

    Using DOS for CaRx

    DOS is not made for continuous duty, but some use them for that. Probably expect a year or two instead of a decade+ from a pump made to be continuous duty. Masterflex is the one that people use that is made for continuous duty and is industrial grade. Kamoer is priced more like a DOS and made...

    Syn's 850g.t.v Deep Brain system

    If you call them, it is usually around $20-30 in the winter for a larger box. The website calculates way too much. 2-3 day ground from Salt Lake City to here works fine on Dry Ice in the winter time. ALWAYS call them instead of using the website. The last few times that Scott and I ordered...

    Syn's 850g.t.v Deep Brain system

    When you take the water out of the different kinds of foods, the po4, protein, etc all end up being about the same, or roughly the same. If you don't rinse frozen food, then the "juice" can add things that you don't really need unless you have NPS and dry food can be a bit better. Pellets are...

    120 Build

    You can bet that they read your email. Give them a deadline for a solution or else chargeback is happening. ...not just communication, but a solution.

    120 Build

    Lots of them send wrong tanks on purpose hoping that people just accept them, or accept them for a discount. Glass Cages was bad about this a decade ago if you custom ordered anything. If they don't make it right, call your bank and charge the card back. This will get their attention. If you...

    Any recommendations for a structural engineer?

    My general thought with most engineers is that they are more than happy to spend somebody else's money - needed or not. Has anybody ever met one that said "you are good?" Probably, but I have rarely met one. If anybody finds one of these good ones, then let me know. :) You can probably do...
