  1. Do you need to do an ammonia test or does that show up on TDS? I haven't changed my di resin in a long time but my TDS meter on the unit still reads zero off the di. I even bought a little hand held TDS meter to check to make sure it was functioning correctly.

     I was having trouble so I deleted the Tapatalk group. When I went to grab it again, it only has the version through Reef Frontiers, and all entries are 2 years old. I didn't know we had a mobile version of the site, so I'm going to give that a try instead.

    I had this same issue, but googled "PNWMAS Tapatalk" and it brought up a random thread. From there it let me follow the forum that was not visible by going straight to Tapatalk. Some kind of weird bat door!

    Trevor can you send me a link of what you had in mind?

    Okay thanks I will look into it


    Seems like this is the cats meow of regulators, but definitely could use some input if anyone has experience with it.


  4. Thanks everyone! This forum is great! 

    I use Kent and this was my next variable to rule out! I'll switch to Fritz and Jeff stocks it at a good price at CC.

    I doubt I'll do a big water change, rather just switch with my normal water changes. So the effects will be slow. I'll report back if I have a major breakthrough.

    Thanks again!

  5. Nicely said Ken, that was exactly what I was getting at. I've just struggled to maintain high alkalinity and just settled for the 7-8 range. Corals seemed to be happy and growing, so just rolled with it. But I always wonder how folks keep it above 9 and thought I might have to crank up my dosing since the consumption rate was going up at higher alk levels. I keep my Mg in check and calcium balanced with the alk, but even so, levels always settle back and maintain in the 7-8 range. I once tried upping the dosing and plastered all of my equipment and rear overflow compartment of an AIO with precipitation. It was like chipping ice off your car! Don't want to repeat that!

    I'm getting close to hitting equilibrium with ESV Bionic in my new setup and may try to push it a bit, but will closely keep an eye on precipitation. My last tank was small and heavily stocked and the high pH of carbonate I think was pushing the precipitation. When I switched to good ole Arm and Hammer bicarbonate, the problem went away. The new tank has more stable pH and I'm dosing in small increments directly over the return nozzle, so this should do the trick. But I'm up to 60 ml/day, which seems high for a 50 gallon frag tank that is reasonably full. But if it's not precipitating out, must be getting sucked up by tank inhabitants!

    In theory, higher alkalinity levels increase the rate of calcification in corals but I think the effect would be fairly modest from the standpoint of calculating dosing rates. So as you stated, within the alkalinity range that is considered healthy for corals it is probably a slight curve but flat enough to assume it is linear.

    Good point. With that said, you may not see much difference until you reach the real extreme ends of the spectrum that most reefers wouldn't be hitting anyway. So in that sweet spot, the difference sounds like it would be negligible. Plus test kit error comes into play. I switched to a Hanna, but still lots of room for error.

  7. I've been using 2 part for the last few years and only briefly got into a good groove when I switched to bicarbonate. I'm trying to dial in my new tank and decided to try ESV Bionic. During my daily testing. I was curious if Alk consumption occurs at equal rates throughout the range. I realize that coral may build their skeletons at different rates during the day than at night, but do they consume more depending on the availability in the water? For example, will they consume more at 9 than at 8? Supplement calculators are truly linear in their calculations, but curious if it is really a curve. I would assume low Alk (below 7) would cause corals to slow down calcium carbonate building. Any thoughts?

  8. Looks like a lab! Good idea in adding an exhaust fan. I have my setup in the basement and underestimated how much moisture it would pump into an already moist place, thinking about adding a fan myself.

  9. Evaporative cooling works amazingly well on a smaller tank of your size. I don't have AC and my old tank would cool down 2-3 degrees in a half hour with just a small 3.5" computer case fan. I think folks use these to ventilate light hoods as well. I just laid the fan on top of my mesh cover blowing down and hooked it up to the Apex. Just need to make sure it doesn't start fighting your heater.
