Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Agree with @saltkreep88 ....you'll be just fine. There actually is no need for that off-centered brace.
As far as the top is concerned, my preference is to top with 3/4 plywood. My reasoning is that dimensional lumber has slight lumps, bumps and twists, so that it potentially is not...
I have four MP's...and I like them, but they are costly. I like two things:
1) They are not as bulky as conventional powerheads.
2) AC wiring is outside the tank.
With that said, I very recently purchased a Jebao PP 15 for 70 bucks, and holy carp, does that thing push water. I think it...
What gets me is that this is a knock-off of the HM Digital TDS meter....that's only a couple bucks more......and this Mudder is known to be inaccurate and unreliable.
Mark, I'd try cleaning it in vinegar over night and then rinsing it well. Then, once you put in in the solution you wish to...
One more thing, if you make large batches (that aren't measured out per batch of 2 1/4 cups baking soda), once baked, the volume has been reduced, and you now only need 2 cups of the baked baking soda (sodium carbonate aka, soda ash) per one gallon of RO/DI.
James, first off I'd suggest actually baking the baking soda at 350 degrees for one hour. The increased temperature assures all the bicarbonate will be converted to carbonate. And one hour isn't written in stone either....if it goes a little long, it can't hurt it. One batch I baked I...
Wow! My Mom typically bought me underwear and socks. :ambivalence:
You're Mom got it right! :dance: Merry Christmas.
Now DIY that two part......HERE's a good start.
I agree with @saltkreep88 .....Jagers are the best. Their glass is twice as thick as other glass heaters. The only thing I don't like is how long they are. And always have backups ready to go.
Herb I have extras to hold you over the holidays if you need them.
@art13 , I'm not sure what you do to maintain alk and calc, but by "fixing" your salinity, you also raised up you alk, calc and mag numbers. That is a possibility of why you saw improvement. I don't think it was the salinity alone.
I fully agree that 1.o22 isn't going to kill corals.
However, I am rather adamant that calibration solution should be used to calibrate your refractometer. Otherwise, I suggest going back and using a swing-arm hydrometer to measure salinity....about equal to a refractometer calibrated with...
