The tanks drilled by people in Youtube videos seem to use a 1" bulkhead on drilled aquariums. I'm wondering if the diamond hole saw drill bit should also be 1" or if it needs to be larger. They're expensive so I don't want to buy the wrong ones! Does anyone know what size Cory uses in the old video where he's drilling 20 gallon tanks for his fish room?
The bulkhead manufacturer should provide the relevant information on what size hole is needed. I have bought mine from BRS and their webpages show what size hole is needed for each size bulkhead they sell.

I have noticed the exact same change in my water chemistry with stratum.
My tank water was (which is straight from the tap):
pH 8.2
KH 6
GH ~150ppmA day after adding the stratum the the tank the pH dropped to 7.4.
Tested the water this morning approximately one week after adding the stratum?
pH 6.0 (almost off the scale of the API test)
KH 0
GH ~120ppmThere is a handful of plants in the tank: some sußwassertang, a water sprite, S. repens, and a moneywort, and other than some hitchhiking snails, there is no other livestock.
It has been enough time for the water chemistry to stabilize after adding the substrate. I am not sure how long the substrate can continue to keep the the KH and pH suppressed from tap water.

They can absolutely be had, but the permitting requirements for them is pretty steep.

I am coming back to the hobby after about a 10 year absence, and the last lights used on high energy active substrate as well as Walstad tanks were T8s and T5s so I am still coming up to speed on brands and LED technology in general.
I bought a hygger light for a 10gallon low energy tank that is going to be a heavily planted tank and it has 4kg of Fluval Stratum in it. The stock is unknown as of now until I am sure where the pH is going to settle with my tap water (pH of 8.2, 6°KH and 250 ppm GH from the tap). I know the Stratum is going to pull that down a bit, but until I know for sure, I am not making stock decisions until I know for sure, but Xenotoca doadrioi are pretty high on my list.
I am still on the fence about which light to put on the 38 gallon. It is a strange size tank 36 1⁄4 x 12 5⁄8 x 19 3⁄4 (same footprint as a 30 gallon long, but 3" taller), and will be high energy (CO2, fertilized substrate, and water column) which is why I initially looked at some of the Finnex lights. It seems only time will tell, but once all of my hardware arrives and the actual build starts, I will create a thread to document its progress.

If you are just going to do CO2 injection on a single tank, there are some Citric Acid/Bicarbonate kits that steel/aluminum cylinders and dual stage regulators. They can be had for ~150$ plus the citric acid/bicarbonate supplies (which are cheap, comparatively). They require a bit more maintenance and have to be home refilled more often, but they are far and away more economical and much more reliable than the traditional DIY Soda Bottle systems.
If you are going to inject into more than one tank, then the bigger cylinders make moire sense IMO. If your tanks are close together ~50' or so, you can buy a regulator with multiple needle valves/bubble counters from CO2Art and Greenleaf Aquariums that will allow you to feed multiple tanks from a single tank.
AquaTek is another brand of regulator/solenoid combo that is a bit cheaper than some of the premium brands. I have previously used them and had no complaints with them (just ordered a new one for a new setup). There is also a COOP video
where @Coryis installing one in the plant rack in the retail store or the warehouse. He specifically mentions AquaTek by name, and AquaTek is the brand that they used to sell.
The video is a few years old, but in my limited experience the quality of their equipment has not changed appreciably since that video was made.

I have the 150 watt ehime
It sounds like the heater is just not calibrated. If you have a known good thermometer, you can use it to adjust your heater.
Keep adjusting the heater upwards, i.e. turning the blue ring, in very small adjustments, until you get the water to the temperature you want, based upon the measurement from your "known good" thermometer. Once you get the water where you want, you can turn the red ring on the heater to match the temperature of the water/thermometer.
It has to be done slowly so you always know that the heater is at equilibrium with the water (i.e. it just maintaining the current temp, and not still heating and raising the temp), and your thermometer has to be of known good calibration, otherwise you are still guessing.

What is the difference between a 40b and a 55 wouldn’t the 55 be bigger
40 gallon breeder - 36 3⁄16 x 18 1⁄4 x 16 15⁄16
55 gallon - 48 1⁄4 x 12 3⁄4 x 21
The breeder tanks are generally not as tall, and have more depth. Between the two the breeder tank is about ~6" deeper and ~5" shorter.

I got in big trouble for bringing a copperhead to class in 5th grade. The science teacher put it in a 10 gallon aquarium with a screen top and killed it by pouring formaldehyde on it.
Heh,similar story here, though I was not the culprit. I grew in a rural farming town in SW Texas. It must have been 2nd or 3rd grade, we caught a Louisiana Milk snake, and one of my friends/classmates took it to school the next day and let it go in the class. It was 'found' in the classroom water fountain. The teacher thought it was a coral snake, overreacted and class was evacuated for a bit while they found someone to catch it. My friend tried to tell the teacher what it was, and he/we were responsible, but she was having none of it, and would not let us pick it back up.
Shrug, good memories.

Bunch of grumpy old men!
I just missed 70's by a year or so. My first tank was in 80 or 81.

Ok awesome my discus right now are at 82 so I will raise the temp. I have another question I have a ehime heater and I can’t figure it out I have it set at 89 degrees and it will get to 82 degrees am I doing something wrong?
What size is the heater? In a 40 gallon tank (~150 liters), the bare minimum size heater (according to Eheim) would be 150W. As @Schwacksaid though, heaters are generally rated based on their ability to raise water temperature ~10 degrees above ambient. If you need to raise the temperature of the water more than that 10 degrees, i.e. your room is cooler than about 75F, then you will need more heater wattage. The safest way is to add a second heater of the same or slightly smaller size, so if one of them fails on, then you have more margin for recovery during the failure.

The SF-500 model is symmetrical, which as @Daniel has noticed, is important to this particular Nerm.
This exactly why I still have and use Marineland BioWheels. They do not always auto-start after power failure, but with the motors molded in the chassis, they are less likely to leak, they have plenty of volume for media (I use coarse foam in the bottom Substrat Pro on top) AND the lids do not rattle.

I have been playing with a Nicrew light for the last few weeks, and while it is a pretty decent light, I feel for the $$ the Finnex (a little more expensive) might be a better option.
I know the COOP only sells the model 1 stingrays and I am curious why. Does anyone have experience with both care to weigh in?
-
As many have said before, two smaller is always preferable to one larger heater so if they fail on they hopefully do not boil your tank before you discover it and can react.
Personally, I have been using Jäger heaters since before they were owned by Eheim (i.e. Ebo Jäger) and I have never had one fail on and cook a tank. Plenty of them have failed, but never on. Granted my experience is purely anecdotal, but after 30+ years in the hobby, I will never buy another brand heater, only Eheim.

I just let it settle along the substrate of the tank.

😭😭😭 my LFS sent out a message of their new fish with those on the list. Every last one was gone by the time I got there. I'm going to live vicariously through you till I get mine. Keep the pictures coming!!
these can be had through the Aquaculture store pretty reasonably.

It's called Poret foam. I purchase them as a kit from Swiss Tropicals.
Apologies in advance if this is answered elsewhere, my forum searches did not turn up any results.
I am a die hard sponge filter user, and am giving the AQCOOP sponges a go after previously using the 'hydros'. I am curious what PPI foam you are purchasing from Swiss for your mattenfilters? I am thinking the 30ppi is probably the best kind of general purpose foam size, but am looking for alternate opinions.

Isn't mulm the "mud" that root-feeding plants eat? I don't actually understand whether or not it's desirable to have.
Mulm is indeed 'good' it is a haven for beneficial bacteria, paramecium, etc.

There is a gentleman on YT that has quite a few videos about this very subject. His name is Dr Kevin Novak. He promotes what he calls a plenum, which is an undergravel filter (usually not the whole bottom of the tank) that has very very low flow, just enough to keep the bacteria alive. He does seem to have very good luck with his filters.
I have been poking around the scientific literature, but with my local university libraries closed due to SARS-COV2 I have been limited to the the abstracts available through google scholar so I do not have the full papers of each. In my limited research, I have found several papers that suggest plants prefer NH3, as well as several others that suggest plants have a preference for NO3.
My curiosity along this line started when I found Dr Novak, and was curious about whether or not I should put a plenum in my new 145l tank. (i.e. is removal of NO3 by methods other than plant uptake desirable?). As of now, the jury is still out, but I am starting to lean the "no it is not" way.

Can I cut that runner off at the base of the Mother plant and move them so they are where I want them?
Yes, once the runner has a goodly amount of runners on it. You can cut from the mother plant and replant.

Honestly, You can grow a lot of great plants without CO2.
If I were putting together a tank that large, I would sort the lighting out first, and use 'easy' plants. Then later on if I wanted some of the more demanding plants, I would buy the CO2 system.
-
I have previously used Milkwaukee and AquaTek and had good luck with both. I just bought a new AquaTek for the tank that I am currently working on.

I also remember hearing Tom Barr, and some other speakers at the Aquatic Gardeners Association over the years talking about the benefits of fine mist CO2 bubbles, over strictly water dissolved CO2. I have never seen their studies in that regard, but their findings seemed to coincide with what I've seen in regards to growth.
I have read this before as well, and not from Tom B. Like you I have not seen a scientific reference that micro-bubbles are more easily absorbed versus dissolved CO2,
It does stand to reason they would as most plants grow better emersed versus submerged. That could be attributed to the difference in the CO2 concentration in the air (~400ppm) versus the concentration in water (~30ppm +-).

Thank you for the "Let's make this easy" podcast

I dose my plants similarly with custom mixed potassium salt (K2CO3, KH2P04, K2SO4) solutions, depending on situation.
