Nice package deal! Though I found out I might have been able to get a better deal on the CO2 tank alone when I had it filled by AirGas, Im completely satisfied. I did have a defective check valve included but AquaCave sent one out the next day!!! The system works wonderfully so far but it has only been operating completely now for 48 hours. But to be able to modify all aspects of this system is great! Based off others reviews, I chose the Gen X media and am satisfied by it. I also chose the 10lb tank and Milwaukee controller and regulator. All systems are working perfectly. The controller keeps the pH in the reactor 6.6-6.9! I would recommend googling the directions on how to install the regulator as the ones on the box are a bit lacking detail.

I bought an octopus 140 reactor for my 100 gallon mixed reef tank and bought this package for it. It took me a while to figure out how everything worked because I'm so used to dosing. When its all set up you'll be very happy you have to dose all the time to keep up and maintain the calcium. I especially love the bubble counter. It was great to have it all together love it very much. This is a great hobby and if you are serious about it you must invest in the beginning and then get your corals later. I will definitely tell my friends about this item.

When doing my research I could not find another packaged deal as good as this one for the price. I researched each product offered individually for weeks before making my final decision. The reef fanatic regulator had nothing but good reviews everywhere and when I compared it to the standard Milwaukee Instruments with its 50/50 reviews I decided the extra $50 was worth it in the long run. I also decided to upgrade my media to the gen-x since it received a lot of great reviews. I compared it to the arm brand and a lot of people said that the arm sometimes turns to mush and has to be replaced early on and therefore they use gen-x instead which is more solid. I stuck with the Milwaukee Instruments pH controller because I know a lot of people that have it and have never had a problem. Aquacave offered fast shipping and each product was individually packaged to survive a nuclear blast which was great. If the right combination of products are chosen than this package can definitely receive a 5 star rating and I would definitely recommend it to friends.

this is a great combination of tools to have for someone who is starting off from the start like me. The only thing that was missing is a "set up instruction manual". in which you can easily get the info from the internet. Oh, by the way before you make the purchase make sure you know where to fill up the co2 tank otherwise this combo is useless.

once tuned to your system, your coral will grow very rapidly. Great product, love the Milwaukee pH meter very reliable. I have had mine for over a year and still haven't replaced the probe, and believe the probe will last a least another year or more. P.S. use a kalk reactor to keep P.H. from dropping to low.
