    Is this diagram okay?

    Another thing you can do is put a valve on the the plumbing and just not use the hole right now. Just have your return come back up and over like everyone thought you were doing in the first place. Later you could use the hole for a closed loop setup with the hole being the intake and the...

    Is this diagram okay?

    one way to do it: Put a threaded tee in the 1inch pipe. The threaded part being the 90 degree part. Into the threaded port, put in a [hr] fitting. It will have 1 inch threads on one side and a 1/4 or 1/8 on the other. To the [hr] you can attach a line - make sure you clamp it. Run the line...

    Is this diagram okay?

    Don't put a hole in that setup as it won't work - you'll get wet. With that setup you will need to make sure your sump can handle water draining from the tank all the way down to the outlet or you will have to tap into the line with a tee and maybe run a small line (3/16in) into the tank (over...

    how would i mount my MHs

    The reflector has several mounting holes in it. Some on the side, top back. You can add braces to your canopy to screw it into or you can run a cord down from the top and attach using the holes. It really depends on your canopy and your DIY skill/creativity. Think about airflow, access, security...

    dripping Kalk

    Use a pressure switch instead of float. They are more expensive but don't have the sticking problem or the snail problem. They do cost more however.

    What Kind of Tank to Choose

    Regarding SPS and seahorses - SPS require lots of water flow, something that isn't recommended for seahorses.

    Also when you do monthly tank maintenance make sure the hole siphon break hole is free of obstruction (algae, corraline, etc.). Something I learned the hard way.

    Is there a way to tell?

    Look on the membrane itself. It will probably have some ID on it. Also look at the restrictor for the drain. It too will have a number - this needs to be matched to the membrane output.

    cpr bakpak 2r help

    The oring goes around the cup and allows you to adjust the height. The bottow edge of the cup should be close to even with the top of the water. It may need to be slightly higher or lower (usually within 1/4). The water in the cup should be like dark green tea, adjust the cup to get it there. At...

    How to replace my center brace

    Plexiglass is a trademarked brand of acrylic BTW like Kleenex is a brand of tissue. HD stocks acrylic sheets in 1/4 but I don't remember the brand but it shouldn't matter. You can cut it with a table saw or a circular saw - since you are screwing it the edges won't need to be perfect.

    Calcium reactor vs. lime water topoff

    Cliffs note version: Limewater is adding lime to water, mixing it and slowly dripping the Calcium hydroxied into your tank. Maintains Calcium and Carbonate (Alk) and keeps the pH on the high side. Relatively cheap and easy to do. Water + pickling lime (or Kalk mix if you like to spend the $$$)...

    RO/DI price difference

    My water general untit took my water from 106ppm to 6 ppm at RO stage and 0 at DI. Very happy with it so far. I do think I will buy a full vertical DI unit when the media starts to go bad tho as I have heard they are much better and last longer.

    looking for a good powerhead

    Does Rio build the Seio better than their other junk? I had a Rio 600 catch on fire in the tank (yes under the water) a couple years back, haven't put anything remotely Rio made anywhere near the tank since then.

    Bad Di Filter

    Doubtful. Have a TDS meter? That is the best way to know if your DI/RO unit is working.
