February 10th Update

Swapped out the old Maxi-Jet for a Jecod/Jebao RW-8






Experimenting with a terracing? type look. Staurogyne Repens -> Bucephalanadra Raven -> Windelov Javafern


Couldn't get a good shot here, the Staurogyne repens is a light shade of green not white


To do list:
Try to get my ph to drop faster, currently it drops from 8 to 7 ph in 1hr 30 mins. Would like to get it down to 1hr. Hopefully I just have to do some adjustments with my needle valve and now have to build a new reactor.
Up my DTPA 11% or CSMB. Ludwigia Rubins is showing an iron deficiency.

Beautiful look tank and very cool setup. I just have to ask, how did the guppy sneak in with the shrimp :)?
When I went to go get Amano shrimps from petco the employee accidentally netted the guppy lol. It was a tiny fry at the time.

Added more S.Repens thanks to @Sean W.




Some of my Ludwigia and AR Mini are looking a bit rough due to my co2 running low for like a week. hopefully everything recovers soon. the area behind the driftwood fills kinda empty, dunno if i want to fill it with more stems or try a moss wall

retired my old 2" x 19" rex grigg reactor and upgraded to a 2" x 45" one. the new reactor is on a separate loop and exits near the main pump

Beautiful presentation, and very nicely laid out.

I'm sure it will look even more spectacular as everything grows and fills in.

Nice work!

And looking forward to seeing how the flow meter works out for you.

got it installed the other day



40 cc/min @20 psi working pressure and my ph hasnt dropped much after 3hrs, think i might need to get a different flowmeter with a higher range lol

Couple of things you might want to check...may or may not be the problem:

1. Leak check the push to fit connections - I had a leak there when I first installed the flowmeter

2. On my 65gal tank, I am running at about 15cc/min and get a pH drop of 1.0 in about 75 mins. Are you happy with the efficiency of your CO2 reactor? From the video, IMO inefficient CO2 diffusion in the reactor. Do you have a valve to adjust back pressure?

edit: that vid above is from before i installed the flowmeter

not sure if im happy with the reactor yet, literally finished it a couple of days ago. do you think the inefficiency is due to my pump? im starting to wonder if my jecod dct 6000 running on the 10% setting is still too strong for the reactor. i have a ball valve near the outlet of the reactor, guess i'll adjust it too

welp found the leak, it's the flow meter. near the threads betwee the o-ring and ss inlets

whats your KH and degassed pH?

video of the diffusion set at 25cc/min, didnt record one at 40 cc/min

kH is 8 and degassed pH is 7.5.

Even at 25cc/min you are losing a substantial amount of CO2 in the sump. From my experience with Cerges reactors, I found higher flow with back pressure is more efficient. I use the DCT 6000 as my main return pump. The Cerges is fed independently by a Ri0 1100. At 10%, your flow rate (assuming no head loss) is 158gph. The Rio is rated at 382 gph.

Suggestion: Drop the CO2 to about 20cc/min, up the DCT 6000 to 30-40% and partially close the valve on the reactor's exit. Play around with the flow rates first till you see no micro bubbles in the sump. Only then increase the CO2 to reach your desired pH drop in a shorter time.

If it's any consolation, setting up the Cerges and fine tuning it was the most frustrating thing for me during my initial set up. But be patient... work with one variable at a time and you will find the sweet spot!!

i was looking around last nite and i think the dct 6000 at the 10% speed setting is actually kinda of misleading. i also assumed 10% = 158 gph, man was i wrong lol

Found this chart on monsterfishkeepers:


and this from reef2reef:
DCT-6000 (42W) Maximum flow rate of up to 6,000 litres/hour - adjustable from 2,900 - 6,000 litres per hour in 10 steps.
•DCT-8000 (65W) Maximum flow rate of up to 8,000 litres/hour - adjustable from 2,500 - 8,000 litres per hour in 10 steps.
•DCT-12000 (85W) Maximum flow rate of up to 12,000 litres/hour - adjustable from 3,800 - 12,000 litres per hour in 10 steps.
2900 lph is about 766 gph.

used the headloss calculator from reefcentral (chose the rio 2500, similar gph to the dct 6000 on speed 1) and got 508 gph after head loss.

tbh i didn't expect fine tuning the co2 tbh such a pita with a huge reactor lol

i've also considered just grabbing a measuring cup filling it with water and inverting it in the tank or sump to measure the co2 through displacement, i think tom barr did this for his bigger tanks. think he aimed for 100 ml / min in his 120 or 180

Something doesn't seem right there. Either leaks or gassing off in the sump.

For reference, in my 120 gallon my flow rate right now is at about 35 cc/min, and I drive my pH down about 1.2 points in an hour. I also use a pH controller or at that rate I would gas the fish. With no controller I couldn't have it higher than 25 cc/min.

I have mine going into a 20" Cerges. No sump, all canisters. And I have a lot of surface agitation. My ten pound tank lasts three to four months.

yeah that's what's been bugging for the past few days. no leaks from the regulator, no leaks from the push to connect fittings, no leaks from the reactor itself. only things left is the off gassing of the sump or there's something wrong with my co2 tube (i doubt it though since its from GLA). maybe i just built a crappy 2" x 45" reactor lmao

Not a big deal, because I do the same thing, but choosing a return pump based solely on GPH is inaccurate. You have to take into account the maximum head height. I was watching something on elbows affecting flow and they had similar pumps GPH wise, but different max head heights, and they flow with elbows and return pipe sizing was quite different. Head height plays into the pressure the pump can put out, yada yada, something complicated. But it is something to keep in mind.

Back to the CO2 talk. I'll be reading it and saving the information for later. I found out the company that does our fire extinguishers at work will refill CO2 tanks.
