How are the fish doing? We are here to help :)

If you follow the video tip in the following post you do not need a bulb or strong lungs. Pro tip: If you have a shut-off valve, close it when the vacuum tube is almost empty, reflood the tube underwater, open valve. https://www.fishforums.net/threads/how-do-i-use-a-siphon.482665/post-4195775

Good luck to the both of you

I see what you did there :D

The outlet pressure and flow rate is directly proportional to the difference in height between the top of the tank water and the outlet of the siphon.

I would also post a link to that thread in the message so that if a new thread was created, a link could be made back to the original for context. FWIW, I usually look for New Posts, so even resurrected threads will be seen.

I've got my eyes peeled for an opportunity to jack a thread to a sub-thread, but I don't want to force it. The elephant evolution thread was a prime candidate, but I was sure the spawned thread would be quickly nuked and I want the first jacklett to shine :)

There is a traditional Mexican place in downtown Macon that serves beef tongue in many of the dishes, I do want to try that.

I first saw these in the offal section at Dekalb Farmers Market in Atlanta GA area. I'm not sure I would try them. We always thought that they were fictitious but I have seen them with my own eyes,

What is a unique regional food from your location or hometown (city or region)? What would you serve to or treat a visiting friend? My hometown is St. Louis MO, which has the following that come to mind: St. Louis Style Pizza - Unlike other styles of pizza (e.g. NY or Chicago) you really...

I SO want to do this. Did you plant last fall?

My original question was not to imply a missing link.

Dose and time?

I have some Pothos that are picking up a bit of BGA (Cyanobacteria) on their roots. Do I need to remove this, and if so what is the recommended technique?

I thought rainwater has a pH <7.0 due to slight carbonic acid from the CO2. This is what dissolves limestone to form terrestrial caves.

Here is my Neanderthal DNA summary

Fair enough. What about the first question?: So what scientific proof do you have that microevolution (which we have agreed exists) cannot lead to individuals that cannot interbreed?

So what scientific proof do you have that microevolution (which we have agreed exists) cannot lead to individuals that cannot interbreed? Was H. neanderthalensis a separate species from H. sapiens?

I watched this the other day and it made my head hurt

This does not answer the question as to why microevolution cannot lead to new species. What is your definition of a unique species?

I realize this is your definition, but there are several problems with this. It is tied to one evolutionary path; and it is not time invariant. IOW, you are looking only at a specific evolutionary path in the past. What about the future? Could humans (or other species) evolve into separate...

What I was asking is if there is a difference in how the evolutionary changes occur, or if the difference between micro and macro evolution lies in the end result? Since we can agree that micro evolution is scientific fact (It is a feature of sexual reproduction), what precludes macroevolution?

What do you mean, how does the process differ from what I described above?

Not to hijack the thread ;) , but my daughter will be at Oxford U. in a few weeks for 6 weeks, then to the EU for another 7 weeks. I hope this heat wave goes away, if only because she is extremely limited on her luggage allowance and is already packed and ready to go on her current campus and...

Generational changes in genetic makeup driven by both the innate sexual genetic variance and environmental forces that either favor or disfavor those variances in reproducing individuals.

As I've gotten older, the heat and humidity is less stifling, as long as I'm now working outside. I grew up in St. Louis and honestly I think it was worse as far as humidity goes. GA has longer fall/spring season and a milder winter. I've heard that the larger cities in AZ have driven up the...

It looks like relief may be in sight https://www.wunderground.com/forecast/gb/leek/ISTAFFOR6

This is a genetic change. The offspring (that survive) are going to not have those genes that produce long tusks. It's evolution.

I think the driving parameter would be RH (Relative Humidity). As RH rises, the temp drop due to evaporative cooling decreases. Phoenix is probably much less RH than the OP location.

While sand is better for Corys, other substrate will not doom them if kept in good water conditions. Unless you rehome your solo Cory, I would add more after your problems are sorted out. I've had my Corys on a non-sand substrate for about a year and they are doing fine, I do plan to change to...

This setup for cooling electronics looks interesting for anyone with chronic heat waves. Lots of details and experimental data. https://www.overclockers.com/the-fountain-cooler/

Aren't these really the same at the biological level?. Selective breeding is just humans tweaking the probability curve by selecting traits (intentionally or not) that we wish to enhance or diminish.

Breaking a volume of water into spray or mist greatly increases the surface area to evaporate compared to a larger volume of water. This is sometimes done for industrial cooling. The rub would be in the implementation in a tank.

As will water changes. It's a tiny tank, scoop the water out, add a few drops of conditioner to water jugs, wait 20 min and pour it in. Getting an air pump and a sponge filter would also help.

I've always wondered if a micro fountain with fine jets would help to increase evaporative cooling. Of course, this would work best in a desert environment. Even a fine spray bar, with an open top, with lower water levels to allow more air contact.

If it were me, I would follow the advice given above re: Platies and work with members here to get your tank ready to accept more Corys (not now!) in the future. They are great fish, and once your problem is sorted out, you will be glad you stayed the course. Stocking experts here can advise...

Increase water flow if you can to increase oxygen levels at higher temps. This might also help heat transfer a bit, though cooler water from evaporation should sink and bring warmer water to the top. What do you anticipate your room temperature to reach during the day?

I agree, the main reason I am testing now is to monitor nitrate - Both to see the best balance between a good environment for my fish, and reduce 50 gal water changes - and to see if my Riperians are having an effect on nitrate buildup. I know my ammonia and nitrate nitrite is zero so I rarely...
