Anyone using a sump?
I thought it might be nice to get all the gear out of the tank and into a sump but haven't got any encouragement from my local aquarium store. They said it would cost too much CO2 but they're still using bubbling diffusers while I dissolve my CO2 externally in the return path from my filter - a 5 lb cylinder lasts 6 months for my 55. Be nice to just have a power head and nothing else in the tank. I'm setting up my 2 20 gallon tanks with a sump anyhow so I'll see but wondered if anyone else is doing this. Thanks.

quite a few people here are
i have two tanks wit them now. and im one step past sump, i have a wet/dry filter which does exchange co2 fairly readily.

if you set your sump up properly, you will increase oxygen levels and still retain much of you co2, such that the 5 pound tank will last maybe say 4 months?
not bad considering my 20 lb lasts me 2 months on my 75 gallon :)

I also have a 75gal with wet/dry sump. Will be posting a few new pics here in a minute.

I have been using sumps for over a decade on 100+ gallon tanks. When it was >3x tank volume it was quiet enough with a single drain but now I have ~6-8x the double Herbie type drain is silent and I only hear the pumps. Hoping once the doors are on much of that will be gone and the more I fuss with stuffing foam between pipes/tubes and what they touch the better it gets as well.

There shouldn't be much more CO2 loss with a sump with a calm water surface as with a canister. My skimmer usually drops water an inch or less so very little turbulence there either.

You forgot how nice it is to have a constant water level in the display tank!

Now that I have an old tank for a sump instead of a rubbermaid tub I can even put the thermometer into the sump if I like. Drop checkers could go as well but since they are for noticing that CO2 isn't going in probably wouldn't be a good idea as too out of the way for quick checking. If the overflow box is where you check it regularly and there is room the DC and thermometer could go it there.

Thanks I just read your new tank thread after I posted this and saw another thread started by someone about a sump. You're new tank is awesome, BTW.

For my 55 I have a canister filter, a denitrator, and a CO2 reactor which is run by my pH meter and is piped into the return of my canister. Its a glass aquarium so I was just going to put together an overflow stand pipe for the water level and run the pipe over the rim of the aquarium. So all my gear will be in or plumbed to the sump which will pump to the aquarium. The overflow is air pressure driven so after painting it out Ill just have it and my power head in the aquarium.

So thoughts/comments on the above layout? Thanks!

I just rigged a common 5 gal sump to my 2 20 gal tanks with the same equipment as I have for my 55 so we'll see what happens.

I have a space 20"W x 15"D x 20"H under my 55 in the cabinet so Ill order plexiglass and glue a sump together to those specs (6000 cu in = 25.97 gal) or a little less, if I use 1/4" instead of 3/8" plexiglass which is $100 less per 24" x 96" sheet.

Re: Anyone using a sump?
How "clean" are tanks with sumps or wet/dry systems in terms of clutter? I currently have a canister with spray bar and intake visible, along with a PH, and would like to minimize further.

Is there a preferred ratio of sump to tank size?

This clean... oveflow is kinda hidden by the plants i DID NOT trim but being clear with a black background it doesn't stand out much

There is a suggested ratio on sump sizes, but that all changes depending on if you want a fuge in your sump or not. And which bio media you are going with. Some bio media has more space requirements than others, so that will be part of determining your size of the sump.

Sweet Blazingwolf! Do you have a link to your list of plants? I like the red and the green/red on the left kind of looks like my ammannia senegalensis.

HD Blazingwolf 04-01-2013 08:12 PM

i don't have a link.
i have in the ludwigia variety
Cuba , Senegalensis, atlantis, repens, plain red, gladulosa, and pantanal
i have rotala colorata
persicaria Kawa, and Sao Paulo
blyxa japonica
and hygro araguaia
and one lone surviving piece of starogyne repens which will probably be eaten as the others were when it gets just a little bigger

I have a Wet / Dry on my current 90g
I'm setting up another 90g and will be building the wet / dry for that one this week.

I will likely convert a 10g I'm not using into a wet / dry for my 29g, and retire my Eheim 2217 I have on that tank.

I love wet / dry filters. So far, I've had great success with them.

The constant water level in the DT is very nice, I like having nothing running up the back or the side of the tank (my two 90's are bottom drilled), being able to hide the heater in it, being able to dose my ferts into it, being able to pump ungodly amounts of CO2 into the tank, knowing I'm also putting in ungodly amounts of O2 into the tank. There are lots of reasons a wet dry has been excellent for me.

My plants love it. My fish love it. I love it.
