This is a well made tank as you would expect from Juwel The only part of the assembly that was awkward was fitting the filter outlet so that the seal was fully home My main reason for this review is to comment on the delivery Like pjnunn in the first review I was a little wary as I had not had a tank delivered before however I ordered this tank with stand and some cat food It was delivered next day with the complete order well protected and strapped on a pallet When I need another tank Pet Planet will be my first port of call

Tried to get one from my local shop to replace a leaking tank but they were charging way more and could not get a delivery for over a week Pet Planet delivered the next day I was a bit worried about potential damage to the tank in transit but full marks to pet planet for their packaging to ensure that the tank was fully protected Would use Pet Planet again for sure
