Is this a filter integrated with the tank? Do you have make/model number of the filter? It will be easier to craft a solution with more info.

In a pinch, plastic dish scrubbers also work.

I only see fiber filters for Marineland units that use size Z. Have you looked at using a pre-filter? I use one of these on my AquaClear 150 covering my intake tube. https://www.marineland.com/products/replacement-cartridges-and-filter-media/2-in-1-bio-foam-prefilter-125-175-275.aspx You...

There are no holes burned in the atmosphere, by planes or any other device. Fuel is rarely dumped, only in emergencies when an emergency landing is needed and the gross weight is above max landing weight. In the rare event that this is needed, fuel is dumped at high altitude if possible so...

Recently I've been enjoying this Youtube channel, I'm particularly intrigued by the 'computerized' gunsights on the WWII bombers. When my health was better, I used to fly a lot. I was lucky to have a good friend with a G-44A Widgeon where I was often the 'co-pilot', or Gilligan if we were on...

I've read about iron-gall but have never used it as I've heard that it is corrosive in fountain pens. I enjoy fountain pens, along with cast-iron cookware, and tube (or valve) electronics :)

Cool, what do you write with?

I like Glofish, I have a bunch (9 I think) of Black Skirts. They likely are some of the luckiest Glofish as they are stocked in a 125 gal rather than a overstocked nano with UV glow substrate and Sponge Bob jailers.

Downsizing FTW </sarc>

Two obstacles here. Distance and hence time for any probe to arrive. Question: Where is our farthest probe right now? Number of probes needed for a reasonable probability that one was sent our way. And in the short amount of time that there has benn sentient life on earth. You need to...

Do you have data on the margins to support the above. Higher retail prices does not necessarily mean higher producer profits.

Or a stack of $1 bills that is ~2 million miles high

I just realized that what I meant was that you want neither adulterants, nor high molar ammonia. Odd that you cannot get NH3 in water at low concentrations.

An adulterant is a substance found within other substances such as food, cosmetics, pharmaceuticals, fuel or other chemicals that compromises the safety or effectiveness of said substance. Yeah, I know, wiki, but reasonably accurate https://en.wikipedia.org/wiki/Adulterant

I didn't see any recent threads with this topic so ... What is your occupation, or current studies if a student, or if retired/other, what occupies your time other than fish? As for me, I'm an engineering manager in a huge engineering company, with most of my career supporting F-15 radar. I'm...

Now we're talkin'!

Nitrate is not that high, that is my level after a WC. Could there be a systemic insecticide as part of the composition, if it's a rebranded terrestrial tab?

Here is a short bit on cyanobacteria smells. Prompted, but the entire (short) video is interesting on its own.

Somewhat related to the topic, I am about to exhaust my supply of Flourish tabs and was thinking of DIY Osmocote in gel caps. Has anyone here tried that?

I pick up bamboo at Lowes in the dying plant section. They never refill the 'test tubes' that they are rooted in with water and they are a buck or two each and come right back. I've got about 6 in my bypass section of my AquaClear 150 with the inlet set to bypass so the roots get nice, clean...

I've heard that also, and suspect that it is true, but have not checked the numbers. The curious thing is that they are so small and weak that they almost immeasurably move the earth in position or rotational parameters when they erupt.

I am sure we that we affect climate, to the same magnitude that a volcano eruption alters the earths orbit. Then there is the problem that in general, lowering the average temperature is more disastrous than raising it.

At least Ozzy won't die from fibrous 'clots'

Do you have a pointer to the data? These are huge eruptions, magnitudes larger than the largest nuclear weapon, but the mass and inertia of the earth is likely magnitudes greater than the eruptions. I don't doubt that we can measure the effect, I'm just curious as to how large the effect...

When I was in Santorini, our tour guide mentioned that people traded property for limited passage off the island during one of the periods of increasing volcanic threat. They chose poorly, at least for now.

If Yellowstone blows it will take out a good portion of the Western US and part of the Midwest. After that, we will wish that we had done more to increase 'Global Warming' since the particulates will cause an extended period of cooling, crop loss, and mass death for most of the species of this...

Or put another way, who is at the top of the food chain?

Yes, please make two separate ones. Being a protagonist and antagonist simultaneously just tears me apart inside.

By pure do you mean without adulterants (e.g. perfumes/detergents), or high molar concentration aqueous ammonia? You don't want either one of those.

I'm with you on the magnetic field. There is evidence from undersea lava flows that freeze the field direction as they solidify over millennia. I can't recall if there is evidence that such a shift will temporarily cause radiation from the sun to fry us all? In other words, is there a null...

Popcorn is done!

Neptune?

I suppose the mods have been relaxing too much as of late. Heating up the oil ... :pop2:

BB lives primarily on the surfaces, substrate, and filter media, not in the water.

I thought you had Culver's up there?

He is a nice thread on benefits of non-aquatic plants in aquariums. https://www.fishforums.net/threads/alternative-nitrate-reduction-method.476457/#post-4111606

They are Light Emitting Diodes. Generally they run off of a 5 VDC supply and that is usually the largest voltage that is present in the housing, the power supply with 110v is usually in the controller unit or a separate brick that feeds the controller. Since current is proportional to voltage...

Any contact with the impure water (dissolved solids generally have free electrons in the form of ions) is likely on the low end of resistance, if not below. Since this is a series circuit, the driving factor is the resistance of the other connection. If you had been barefoot on a concrete...
