Comments: It has been great so far; inverts are rather vibrant!

<br />With all things in life you get what you pay for. It's very cheap but don't waste your money. Water leaks from the lid. The pump that circulates water within the pump is very cheap quality.

Comments: Not a bad calcium reactor for the price. It is rated right but I would not put it on a larger system and expect it to keep up. I am cosidering getting another and using it for a sulfur denitrator. Price is right for a small reactor.

Comments: When I got it I thought, looks great, simple, compact, attractive, great price. Then I installed it. I've been working with it for 2 weeks now and have had the following problems:
<br />
<br />1. Chamber gasket leaks, it is very touchy. I finally got it sealed using silicone lubricant but it's a new struggle to get it sealed every time I open it, which I've had to do often because of other problems (see below).
<br />
<br />2. The green valve leaked around the stem from the get go. I finally removed it to put sealant on, it has male threads but when I reinstalled discovered there are no female threads in the head plate, it had been glued in. Ended up sealing it with silicone sealant but it's fragile. I hate having to do "hack" repairs but can see no alternative.
<br />
<br />3. The circulation moter to disperse the CO2 is unreliable. Either doesn't work at all or is very noisy. I have not found a fix for this.
<br />
<br />I like the design but this thing is just too cheaply made to be useful.

Comments: Nice Simple reactor. The only thing is the top has a slight leak. Not the best gasket on there. Had to seal it with some silicone. Got it working ok. We will see what happens...Not throwing the box away yet! lol

Comments: I didn't want to pay the $150 plus for a second column for my Korallin 1502, so I got this little gem. I was expecting it to be so-so, but it has worked out well. The control valves on the top are my only complaint. I just decided to use JG fittings instead. I would recommend as a second column addition, as I haven't tested it independently on another system.

Comments: I just bought one for my 55 sps dominant tank. So far I have broken one of the barbed fittings for the C02 water inlet, the seal does not seam to work all that well and the reactor is leaking. Trying to fix the leaks and the barbed inlet and see how it goes but for now I haven

Comments: Pros: well made product; easy screw-on cap; fairly informative manual; works as advertised, definitely for no more than what it's rated; fairly inexpensive

<br />Cons: needs separate pump to feed water into reactor; effluent maxed out at 14-16 dKH; any more than 20 bubbles/min. causes stream of CO2 at outlet;
