I dose something like 72 mL per day of AFR into my 100 L system. It ends up being around 4 dKH per day. I use the full strength AFR and you can’t dilute it (the high ionic strength prevents bacterial growth). My AFR is dosed into a tee on my DI auto top off line and the DI kicks on a few...

Top front. That light blue surface that is on most of the inside is the cooling surface. I don’t think you want to drill through that. The spots I drilled through are just foam with two layers of hard plastic.

Hey all, meet me here on Friday at 11:55. A gentle reminder that the tour will be starting at NOON SHARP and we can’t wait for anybody to join late. Please plan on getting there on time and taking care of all water/restroom/etc duties in advance. Thanks and see you then!

Sorry, but we can’t provide any free passes or discounts.

That’s an odd one. My dad was an ATF special agent for 25 years and I think he never wore a helmet. And it looks like a bike helmet? Wtf?

Sorry, I missed this, but what paper are you referring to? Those numbers seem insane and not possible in water. It might be measuring oxygen inside tissue or something? Where is the link to the paper? Edit: Okay, found the original paper. They were basically measuring isolated reef flats at a...

Let’s chat about the meter via email. Give it to you during the tour. :)

Yup. I haven’t had any issues with the humidity in the fridge affecting the pump performance overtime. YMMV. I used some silica packs for a while but eventually got lazy and stopped.

Hey John, you’re totally right. Photosynthesis changes all this. I should have said it’s best to do this first thing in the morning before lights come on. It’s fair to say that if your DO is 100% or near it at that time then your gas exchange is good.

You may be okay. Depending on the product some of that stuff can sit for that long and still be okay. But I’d compare it to constantly eating food that’s been left out at room temp overnight. Just not great for you. Aside from any nutritional concerns, I’d think you will end up doing more...

Dissolved oxygen is almost always super high in a typical reef aquarium regardless of skimmer/no skimmer. Everyone should test this themselves if given the chance. I have a Milwaukee DO meter I don’t use any more that I’d be happy to donate to BAR. You can sorta use DO as a proxy for how much...

I would certainly purge it. If you don’t, whatever is sitting in the tubing between the fridge and the tank is just sitting there at room temperature. If you’re dosing massive amounts of whatever and it’s only sitting at room temperature for a few hours, maybe not such a big deal. In my case the...

There can be a massive difference in pCO2 between indoors and outdoors particularly in modern homes. It would be fairly normal for pCO2 indoors to be 1600 ppm or about 4x higher than outdoor air. Highly dependent on number of people and how well sealed up your home is.

That one has been running about 18 months now and solidly keeps the temp at 38-40°F https://cooluli.com/collections/concord-edition

Bummer I can’t make it! Chad is the man and has helped me countless times over the years. THE COPE-GOD!
