    I am now running this filter and a sponge filter in my tank ever since my last filter gave up.

    This filter is NOT as loud as the reviews make it out to be. I have a 36 gallon tank and itโ€™s in my bedroom. As long as you keep the tank filled, which you should anyway, it is not loud at all.. Just like any other filter, if it does get loud and your tank is fully filled, checking the filter for debris and it will solve the issue. I sleep with it running every night.. (Side note: I have ADHD so sometimes noises really bother me at night and keep me up, but this filter does not!)

    I have had this for months by now and I have never had a problem with it. The bio wheel does wonders. Between this and my sponge filter, my water stays clear. I am sure this filter could handle the tank all on its own, but after my top fin filter completely gave out after 6 months, I was left without a filter for at least a couple days. Running two filter gives me reassure and extra filtration.

    Overall, this filter is wonderful, I highly recommend it.

    My old Top Fin filter was on its last legs, and the noise was driving me insane. My 36-gallon aquarium is in my home office, so this was a huge problem. I purchased a new Top Fin (same model), but it was almost as noisy right out of the box as my old broken one! Sounded like gravel being ground under a wheel. This 30-50 gal MarineLand makes no noise other than the sound of falling water (which will be lessened when I add more water to the aquarium) and the slight hum that says the motor is working. I’m pleased so far.

    I bought this because I moved up in tank size and I couldn’t be happier! I thought the larger size might be too noisy for my small office where my tank is, but it is very quiet. Tank stay clear and the new fish seem to be very happy. Filter changes and cleaning are easy peasy, and the price was reasonable.

    Box came to the door with no additional padding, just a box like right from the store! Upside down on my doorstep. Turned it over…tinkle-tinkle, uh-oh. Opened the box, everything seemed O.K. Took off the elastic band took everything out. Everything was O.K. Put it together, poured in water , plugged it in, terrific, No sound, good flow, no water tinkle Everything perfect. I have one in my other tank for 20 + years and still works great. To clean, take out the impeller. There may be threads of algae twisted and hard to see. Take off algae with tweezers and even small pointed sharp scissors. Clean out the tubes, impeller housing etc. Also the inside where the impeller sits. I do this with a tooth brush and aquarium snake brushes. Leave the roller alone! Just clean off and rinse the filter(s), they last for months. Effectiveness of charcoal is give or take, lots of hype, little substance. Yes, filters look ugly dirty, again just rinse off and scrape with tooth brush. Change when it clogs up again in a day or three or when blue medium is too thin and charcoal falls out. Been doing this for over 20 years with no fish casualties, everyone is happy you will be to with this filter if it is taken care of properly. Clean when water overflows and roller stops rolling.

    I have kept aquariums since I was knee high to a duck and I KNOW Marineland has a Great reputation for having excellent products. I knew I couldn’t go wrong with a HOB filter, especially being a Marineland!

    Puchased the Marineland Penguin 200 Power Filter, 200GPH May 2023 it has worked well on establishing a new aquarium, Up and Running on a 40 Extra high, Planted Aquarium (substrate: Soil,Sand, Gravel):

    The Filter comes with little plastic lids for the top of the filter covers the Intake/Filter area and the biowheel area. I did have to tape the biowheel cover to the filter due to minimal rattling (Easy fix, NOT a deal breaker) I like this idea of the lids it prevents splashing and lowering evaporation.
    Pump is quiet and has great lifting power to self-prime and great flow!
    The Intake tube is in 3 parts to customize the length for your particular needs. My Aquarium is 24″ tall and therefore required both tubes to ensure collection near the bottom of the Tank. At the midsection of the intake tubing there is also a “flow control” gate/switch built into the tubing to draw in water at the mid level so you can pull water from just the bottom or both bottom and middle. Very cool design idea! ๐Ÿ™‚
    This model has a space to hold 2 filter cartridges which is nice, especially if you have a planted aquarium and your “Finned Babies” are breeding machines! Anyone want some very Healthy and Robust Black Mollies, Molly Guppy Crosses!? lol More Babies = more waste! ๐Ÿ™
    The pump has nice flow and cleans well.

    My experience, as my Planted Aquarium becomes well established/aged…
    Due to my tank size/shape and the inhabitants rapidly overpopulated their forever home, Mollies breed like Guppies, the Filter is not able to keep up with the waste load. I am currently dealing with brown algae in the water column as well as Population control as the filter struggles in keeping the water polished. ๐Ÿ™ (Using API Algeafix and Accuclear, along with 2-3 25-30% water changes weekly and having to rinse the filters every other day (water tests are all perfect, NO Ammonia/nitrates as it should be in a heavily planted aquarium).
    At a loss, I feel the filter is just not handling my particular Aquarium’s demands… I ordered a larger Canister filter (link below) and will put this MarineLand Penguin 200 Power Filter on my 15gal. back-up/hospital tank it has no substrate, and minimal fake plants for the “Fin Baby’s” comfort (should the need ever arise).

    To sum it up:
    I recommend the MarineLand Penguin 200 Power Filter, 200GPH for up to 40 gallon (Max) with MINIMAL population OR Strict Population Control!
    Recommendation: If you have 40Gal and are putting in Live bearers, I recommend going up a filter size or 2 because life throws obstacles at us and before you know it you have a tank full of Live Bearers and they can be tricky to re-home… not everyone has a neighbor with Fish Eating Fish nor can conscientiously send their babies to their demise.

    Also Note the Biowheel is basically useless, it does NOT turn. Do NOT let this one minor design flaw deter you from purchasing this Filter.

    Thank you for your time and Happy Aquarium Keeping! ๐Ÿ™‚

    Canister Filter 370GPH w/UV light:
    Please note that I have only just ordered this filter (Feb 2024) and cannot endorse or recommend the canister filter based on personal experience. The Canister I purchased is based on my needs and has MANY positive reviews. I included this for those who may be in a situation like mine & are curious as to what I am replacing the Marineland HOB filter with. ~Look for my review around April 2024
