Good to deal with but for some reason when items are sent it requires a signature upon delivery which always costs me time running to the post office when I’m not home .

Eheim AquaCorner 60 Internal Filter

I’ve just started using this but I love the large amount of filter media it contains. Very easy to use and a sleek space saving design. Highly recommended

Recently we purchased a range of salt water fish exceeding $500 worth of value. Not for the first time, again we have experienced a devastating outcome, loosing the entire colony, within 5 days of bringing them home, to White Spot. Unfortunately, this was also the case for our first batch, which you kindly replaced. On this occasion, it was evident within the moment they were transferred into the tank under good lighting that one of the fish was carrying the White Spot disease. Our current satisfaction is very low, and would like to have a response in how we could be compensated for purchasing diseased stock. Water quality is perfect and has been proven in store. I still have starfish and live coral in the tank. I have photos which prove the timeline of what happened and I'm happy to send them through to you. Hope to hear back from you promptly.

Great place for pretty most aquarium supplies with very helpful staff and I've always had reliable delivery when ordered online. I have found Tech den limited on some more specialised items like botanicals and plants but overall If it wasn't for distance I would happily shop here more often. The only criticism I would have is the inability to reserve live fish online or at least ring and confirm stock on weekends. It is a fair drive from Brisbane on a Saturday and the website may say there is 6 of an item in stock, but there is no way of confirming that or reservng the item. You just have to take the risk that spending the time and petrol to get there is worth it..
