Planted tank with Sump Issues

goalieman59 · 11-06-2009, 05:06 PM

I have a 120tall tank with a sump, that is gassing off too much of the CO2 that i am injecting and I am having a algae outbreak. I was wondering what i could do to stop the gassing off. Or could I take the sump out and hook a fx5 to the output and input from the tank? Would this work? Will this be enough water exchange? Any other ideas?

you can seal off the sump top openings with plastic lids or saran wrap, this will help keep the outgassed CO2 in a closed system and will get reabsorbed.

I read that on this site somewhere

How are you getting the CO2 into the water?
How do you know you are outgassing a lot of your CO2?

CO2 outgasses due to surface aggitation. If you have an overflow, or trickle filter as part of your sump, these are what is causing your issue. Reduce the distance of the water falls, best if none.

Once that is done, you may or may not need to cover the sump. I inject and don't cover my 135 which is 72x18, keep my CO2 at 30+ so its not all about surface area.

I am putting the co2 straight into the tank via a glass diffuser. The sump is a trickle type, and the over flow is falling about 2inches I plan on fixing that is week end.

ok so here is the idea to redo the sump what do you guys and gals think. Do you think this will help with the gas off issues. I think this will help with the trickling of the water.

I adjusted my sump so that there was lil splashing. the inflow from the tank can go into a larger pvc tube to stop the waterfall splashing effect. Also if you decrease ur output to the tank, you can avoid any trickles over baffles. The flow will still go the way you want, just without splashing.

So you think the set up would work then?

I think it would help a lot. I think the part you have to pay the most attention to is the inlet and floss on the left side. You want to create as gentle an entry to the sump as possible. On the left, I think you are going to drip through floss, as opposed to the bio media that you will rise up through without air. A slight angle on the outlet side of the bio ball area could reduce the waterfall effect there.

Covering it is a big deal as well.

Plus, I don't think that one baffle coming down in the middle is really doing anything.

so you are saying like this, and I was thinking about replacing the floss with a filter sock, and make the tube longer so it sits in the water.

Yup. Perfect, IMO.

Are you building it yourself? Long term, I plan to do a diy acrylic sump just like what you have here.
