Review on 🐠 Marineland PA0145 Magnum Carbon & Media Container 1-Pack: Optimal Water Filtration Solution by Brian Hood

The product is solidly built and better quality than expected. The only thing I'd like to point out is that the plastic twistlock bar on the bottom deforms slightly if you try to press on one side only (e.g. with a small screwdriver), so always go with a pair open and close needles. nasal forceps. Included. HOW IN THE NAME OF GOD DO YOU GET AMMONIA/COAL REMOVAL SUBSTRATE IN THIS GOD FORGOTTEN THING? Serious. How does the inner inlet tube protrude from the rod that pivots and locks it, making it impossible to keep one end open for substrate loading without pushing the plastic grid out of the rails that hold it in place? I'm tempted to just cut a small "door" in the plastic mesh and then just zip it up after I've filled it in. Of course I'm doing something wrong. The Magnum 350 canister filter did not come with instructions (bought used) so any help would be greatly appreciated.
