Air Stones for Sale
The Aquarium Air Equipment is a very important accessory to keep the fish tank energetic. SENZEAL has many professional aquarium air equipment for sale such as Aquarium Air Bubble Stone with LED Light, Battery Air Pump, Aeration Bubble Release Bar, Airstone, etc..

Why We Need Aquarium Air Equipment
While watching the foam rise to the top may be enjoyable, that's not why we need it. Fish need to be dissolved oxygen in the water to survive. They absorb dissolved oxygen through their gills and produce carbon dioxide. When we have a lot of fish in a closed system, we don't have enough oxygen. Sooner or later the water will run out of oxygen and the fish will die.
A simple way to prevent fish from dying from lack of oxygen is to increase the amount of dissolved oxygen in the water. At the same time, we must remove the carbon dioxide dissolved in the water. It requires accelerating the exchange of gases between water and the atmosphere.

How to Choose Aquarium Air Equipment
There are no rules for choosing an air pump. Some air pumps depend on the size of the tank.
If you use an air pump that simply operates under a gravel filter and your aquarium is a standard size, the aquarium size rating on the air pump may be relevant. However, if you are using the air pump for other operations, or if your aquarium is not a standard size, the aquarium size rating for the air pump is highly irrelevant.


Here is some advice on choosing an air pump for your aquarium:
1. The more things you run from the pump, the more pumps you need; Instead, the less you run from the pump, the smaller the pump you need.
2. If your fish tank is deep, you will need a special deep-water air pump to push air below the surface.
The more resistance you have to push the air through, the more bubble stone you need. A large air stone provides more resistance than small air stone, and any air stone provides more resistance than no air stone. In addition, some types of air stone will provide even greater drag than others of the same size.
When choosing an air pump, choose one that is slightly larger than you initially thought you needed. This larger pump will help you make up for the underestimation when choosing the pump or provide a small expansion space if you decide what you want in the future.

Re: Job change after PR application

❰❰ Quote:
Hello.

I applied for PR last August and am considering changing my job.

My profile is the below.
* Chinese
* Mid 40s
* Married with 2 young children
* Financial IT consultant
* Monthly base 10k+

I have been with my current employer for about 4 years and considering 1) move to another IT consultacy, 2) move to a bank (likely one of the 3 locals).
Would either of them increase my chances of being approved? If so, what is the ideal salary hike that I should aim for? In case I move to a bank, would the higher median salary of financial services drag down my desirability as a PR?

Many thanks!
❱❱

If the new position and salary are higher than your current (may be if you go around 14k+), it will be an additional plus.

But at a high level I see your age and current monthly salary may be slight disadvantage to you.

Re: Absolute favorite hotels

Yep, besides the Rendezvous in Perth and Hyatt in Kuantan, the only other place in the world I’ve stayed that beats those is the Makaha Beach Cabanas, where we stayed on our 3rd trip to Hawaii. I just love Oahu’s north shore, it’s so peaceful and rustic, but still easy to drive down to Waikiki if you get bored.

One place I’ve had my eye on for a long time is the Hilton in Hua Hin. That one seems to fit my criteria, but I haven’t had the chance to visit.

Re: 44 yr old guy looking for an expact gf

Why does every post of yours turn into a mini life story? I don't deny you've had a somewhat interesting and long life but why you do have to dump it in every discussion?

On the other hand, your previous reply to the OP was obviously intended to irritate him. Your modus operandi is 1. Insult 2. Tell life story.

Re: Absolute favorite hotels

Thanks for sharing your favorite hotels! They sound amazing, especially with ocean-facing rooms and beautiful beach locations. It's wonderful to find those special places that keep drawing us back. Your descriptions make me want to visit both Perth and Kuantan soon!

Re: Explicit books in international school libraries

I hadn't heard the term ‘cisgender’ until my argument with SAS about their teachings and my immediate impression was that it had a negative connotation… after looking it up, it is apparently a term invented in 1994 by the trans community to label anyone who is non-trans. The liberals then ate it up and regurgitated it to our kids, along with the pronouns and alphabet soup.

I don’t accept the term cisgender any more than xim and xer. It’s not a real term, it’s just make believe, blue pill.

Parents are in the dark about how bad this all is. It was during Covid where appalling school material leaked out to parents. More parents are waking up to this madness.

In SAS for instance, my kids and his friends are telling me that Teachers are indoctrinating students that "Sex is assigned at birth and one can identify with as many as 100+ genders in the gender universe". They intentionally make cisgenders .....
