so which reactor?

[sherry]

I don't think I got a good reactor with my otherwise fine co2 set up.. so which one should I consider for a 37 gallon cube, to make the most of my pressurized system.?

[malkore]

what reactor did you get?

do you use a canister filter? [acronym:6db911f5f8="Hang On Back"]HOB[/acronym:6db911f5f8]?

there's a lot of options, some free, some cheap, some over $50...we'll help you find the best fit.

im going to post this question as it relates to malkores last post. I have a [acronym:122f321665="Hang On Back"]HOB[/acronym:122f321665] canister... i know that seems odd, never seen one before. Regardless, im am considering a [acronym:122f321665="Carbon dioxide"]CO2[/acronym:122f321665] injection system. How do I input [acronym:122f321665="Carbon dioxide"]CO2[/acronym:122f321665] lines to the canister with out drilling holes or otherwise comprimising the filter and warranty

re canister injection -- good thread and methods:
http://www.aquariumadvice.com/viewtopic.php?t=63321 Suggest you post [acronym:5e3f44f039="Carbonate Hardness"]KH[/acronym:5e3f44f039] and pH from tap and after injection if you are unsure about effectiveness while playing.

Can't do cannister injection here.... I have the filstar and I read that they are subject to airlock already. Not worth the trouble if this happens.

I'd prefer to try a small powered reactor.

I got a no name thing that suggests I place it "near" a power head...

if I am going to go to all of this trouble, I'd rather do a better job than that.

so .. again I ask.. can someone recommend a good reactor for a 37 gallon tank to use with pressurized co2

thanks!

Sounds like a passive diffuser (doesn't have a pump or any circulating water in it).

You can indeed use the canister, but you need an inline reactor placed on the return side.
There are lots of [acronym:45546c82a4="Do it yourself"]DIY[/acronym:45546c82a4] plans for these that use [acronym:45546c82a4="Plastic pipe"]PVC[/acronym:45546c82a4] pipe, [acronym:45546c82a4="Plastic pipe"]PVC[/acronym:45546c82a4] glue, and something inside to help break up the bubbles of [acronym:45546c82a4="Carbon dioxide"]CO2[/acronym:45546c82a4]...often times I see marine bio-balls in use (like what you'd put in a sump).

Otherwise, I have a vortex reactor, which is the manufactured version of your basic 'power head and gravel vac tube' [acronym:45546c82a4="Do it yourself"]DIY[/acronym:45546c82a4] reactor.

The dyi 's look interesting, but I live in the middle of manhattan without any nearby home depot like parts stores.. and no car. that and the fact that I am a mom of two tiny kids who really spends too much time on the tank already makes it far easier for me to buy the manufacturered versions of most things.

the only vortex I see on line seems to have a 30 gallon max capacity.. does yours hold up to a slightly larger tank? brand name please?

and thanks! Now that I've decided to commit to co2, I really would love to get set up

Look at a phos reactor, instead of phosphate media put in Bioballs, get the water to flow from top to bottom and hook it inline with your filter, presto, the Co2 will sit in the phos reactor getting broken up by the bio balls and what doesn't get dissolved rises to the top to "ride" again.

They are 31-35$

same concept as below and other high end reactors, but without the pricetag..

I've noticed a company will take the exact same product, throw a new sticker on it saying it's a speciality item and double the price, for example, look at the nitrate reactors, they are the same as the phos reactors, but carry a 150$+ pricetag..

This is the reactor I speak of:

wiz your's looks interesting, but I ended up with Malkore's suggestion since peter at azgardens likes it too. He's been a really great advisor for much and has gone out of his way numerous times to help me, so I trust him hugely!!!

Malkore, when the controller lowers or turns off the co2 ... does the powerhead on the reactor work to help keep flow going in the tank or should I still run a separate powerhead as I do now...?

where do you come out on the controller/timer/24/7 co2 debate?
