Review on 🐠 24-Gallon Penn-Plax AquaSphere LED Aquarium - Large Bowl-Shaped Tank for Freshwater and Saltwater with Integrated Filtration System - Durable Polycarbonate by Barbara Majdoch

2/13/21: Ordered 24 gallons. My "fittings" do not look like the pictures shown here. They don't even look like videos. I had to watch a full screen YouTube video and watch it 5-6 times to see where the airstone belongs: In a protein skimmer, which I can only assume will require the purchase of a separate air pump as I don't have one thinks of a way to connect it to an existing pump. I thought it was an autonomous unit. I don't have any part that I could use to direct the water flow, so: it goes into the filter chamber, exits it and goes back to the water inlet. No circulation in the bowl. I have (2) smaller pieces that fit in the center chamber but they are too small for the exit point. (shown in picture with Penn-Plax decor) I have emailed Penn-Plax twice to ask some other questions but no reply. I'm not sure if it would be helpful to contact them about this. I contacted the seller just before I chose him and arranged a refund. Depending on if they can get me the right part I may be able to return the aquarium which is a shame.
