Is this a good calcium reactor for a 75 gallon?

I have a 75 gallon that will eventually be and mixed reef and i've heard i need a calcium reactor for the sps corals. I found one but it's a lotttt cheaper than the other ones i've seen and i don't know if this a something where you get what you pay for. If i do get this one, what else will i have to get before i can use it? Thanks! here is the link Via Aqua ACRO-Cal Calcium Reactor AC 10 - AquaCave

 

Personally I don't have any experience with this reactor nor do I know anyone that tried it...but if you been in this hobby for some time I'm sure you have learned that with almost any equipment you get what you pay for (there are exceptions). The question is why are other reactors selling for hundreds of $$ and this one only $49?

On a side note, you don't need a CA reactor, there are other options...kalk, 2-part solutions, etc. that work great.

 

it is only 50 bucks cause it don't have anything else with it. no co2 tank or regulator, that is where all the cost come in.

 

I agree that you get what you pay for generally speaking. I haven't used this but I bought a via-aqua media reactor for GFO/Carbon and it really felt flimsy and I didn't trust the hose connections. You get what you pay for. Also +1 to the reactor itself only being part of the expense, but this is quite a bit less expensive than most other reactors.

If you want to take a chance and try using it and being dissatisfied and having to buy a new one in a few months, give it a shot. Cheap equipment can sometimes make life a nightmare trying to get them adjusted and tuned in to your system etc. Especially with a calcium reactor it's dangerous if it malfunctions it could dump a bunch of low pH water into your system or spike the alk/calcium or something which could cause major problems.

 

reactors arent needed to maintain sps.
