Most cichlid keepers don’t pay attention to aquascaping, and most aquascapers don’t pay attention to fish. Yours have both, true living art in a living room with a lot of life. What filtration do you use and how do you keep algae out?

Anything and everything inside of an aquarium is biological filtration media. If it has a surface for bacteria to grow on and oxygen is provided, the bacteria will do their thing. If whatever surface that bacteria chooses to grow on also happens to polish the water, then its even better! The...

The pic in my avatar is a full grown, male harwitgi. It’s a beautiful fish that looks like synspillum or bifasiatus, and can be ID by the slight over bite. It’s peaceful to other fish, but intolerant to other Vieja species in not so spacious tanks as a male can reach 14”. He was the center...

Majority flooding accidents can be traced to part human errors and part equipment. After you clean your canister or AC, if you don’t check to ensure there is no leak from the O ring before going to sleep. If flooding occurs when you wake up, it’s largely human error. But if the equipment has...

Ive known hobbyists emotionally attached to their favorite fish, but emotionally attached to their filter is just bizarre. What keep me up at night is wake up or return home and walk into a flooded living room from a failed tank or equipment.

Regardless of the size of the tank, the destructive behavior of Dovii will attempt to knock off the return pipe. I once had a 14' Vieja (pic in my avator) housed in a 125 that constantly knocked off the strainers from the return pipes. I had to drill tiny holes in the pipe to secure the...

You don’t need a 500 gal tank to house one dovii. A 2 ft wide 120 will do, at the minimum, with good filtration and massive weekly water change. The width of a tank limits the size of a fish it can house.. Since you can buy 2 to 3 Penguin for the price of one AC, It’s a better bang for the...

In Amazon, AC 110 sells for $80 and Penguin 350 $30. It's very clear Penguin is the better bang of buck of the two as you can buy 2.7 Penguin for the price of one AC. The AC foam measured 10"L x 3.5"w 3.5d, and Penguin 6"L x 4"w x 1"d x 2 pads. AC has much larger media volume, but...

Another video of same or different fish market?

Just found this amazing video on fish market in you tube. He has more videos on the same subject. Just wonder which city he visited.

I have PG but they don't seem to be eating bba in my tank. I can tell by the way they graze. PG graze like any sucker mouth pleco, so they are good at erasing green dust algae on glass and leaves. SAE nibble on the leaves and along the edges where bba concentrate. Molly nibble on leaves...

If it is BBA, only SAE will do. If it is algae on the glass, bristle nose, panda garra, snail and any sucker mouth pleco will do. You can help by spraying with 3% peroxide on exposed surfaces during WC, and dose Seachem Excel after WC following recommended dosage.

The magnetic drive motors are made for air cool and touched warm, so don’t count on them to help your heating bill. Because of the low heat generated, they last forever. Sand pumping is an issue with canisters and AC. Most HOB pumps are too weak to draw sand. My goal is to clean my filters...

Juvenile moori look the same and cannot be sexed. I don’t think you can vent them until they are sexually matured and ready to spawn, but by then, venting is not necessary. Older males will grow larger size and hump, but otherwise no difference from females.

If I turn off all equipment, I can hear the hum noise. But you said that your power head makes loud hum noise, that’s not my experience as it makes less hum noise than my HOBs. Hum noise isn’t annoying to me. It’s the clicking noise that I can’t stand. RD said he hasn’t cleaned the AC...

Not sure what brand of powerhead you use that makes loud hum noise. I have both the AC powerhead and Koralia circulation powerhead, and they are absolutely silent. Canister is quieter only because it is hidden beneath the cabinet sound barrier. I have compared canister with HOB side by side...

Don’t forget that the op asked for opinion between AC and Tidal. I have no experience with Tidal. But from the product description, it’s an improvement over AC. It has a motor located inside the tank, so there is no O ring issue. It said to have a bypass channel for clogged filter, so does...

Not true. Penguin and all cartridge style HOBs are designed to bypass flow into the spillway when the filter is clogged. So there is no chance of overflow. When the AC foam is clogged, there is no bypass but pops up and pushes the cover aside. It’s not only unsightly, but potentially drips...

You have already asked the same question on Post 41 and got answers.

Not true. How about this poster. Do a search on HOBs and you will find more. AC is the most popular filter in MFK, but the only HOB reported leak. There are more leaks reported for canisters, and rarely for air hose, but can happen.
