I added the second #4 hydro Sponge to my "sump", and a cool swiveling elbow to the tank overflow output. The elbow was designed to eliminate noise and does, but it also allows me to stop the flow (or adjust it) from the tank by inverting the elbow. Very useful for working on the filters.

I will lose most of the hornwort to total melt. The cabomba I will leave alone as it sends up new plantlets but the hornwort does not. I will have to toss 75% of the bottom of all of it because it is melting terribly. .This wil, of course, set the tank's ability to remove nitrate back.

I found NLS with both the new and old labels. Unfortunately I need the large pellets and those had the old soy labels. I am probably too suspicious, but I just don't trust what some stranger (and salesman) tells me over what the label says, so I will wait until I find a jar of the newly labeled large pellets then switch.

My tank is designed to be low WC because I feel this will, theoretically, tend to be more stable. The success of this depends on what accumulates. Until now I did not know what happened to DOC in this kind of tank... Here's Barr's answer to that question:

"... we export DOC's with water changes, non CO2 tanks on the other hand w/no water changes do not have that export, so then the bacteria start to break it down into CO2 and energy via respiration which removes??

O2 to oxidize the DOC(reduced carbon).

Th low bioloading in non CO2 tanks is mainly to match the low NH4 removal and limited supply of CO2.

Many folks have more fish and more algae, but it's less to do with the DOC;s, but to some degeree that can reduce the dOC loading by having less fish, but plants are also a large source of DOC themselves, like 10% of their fixed carbon is leached out as DOC's..........

Regards,
Tom Barr

So... I won't add activated carbon or purigen... It turns to CO2!!! HA HA HA HA! (you win some )

I may still have to consider using zeolite though... The jury is still out on what my plants can do with my bio load, though. And more plants may come. Emergent plants should take it up a notch or two.

Another species?

Val would be the natural choice for another plant. Egeria needs higher light. Vals are not supposed to like Ph as high as mine but my mini's are fine. Vals would take more ammonia than nitrate but that's fine as it reduces nitrate production. Once they emerge they should not only grow quickly but also leave the water CO2

I was mistaken about my hornwort melting. It is merely beset by diatomes, so I don't need to cut it back. It might not hurt though. I don't think the bases grow at all and don't know if the stem bases help the overall growth or not. Perhaps if I were to prune the bottom half the growth would be unaffected??? In any case, the plants adapting to my parameters is the main factor in their performance, and will take time. The plantlets are up to ten times as fast growing as their parents.

If I am right in thinking that I had an ammonia spike from killing too much algae at once, what should I have done? (besides WC) most people would have reached for the Prime, but I wonder if it wouldn't be better to keep some Stability on hand for this kind of event. Besides taking care of the ammonia spike, the bacterial boost could help keep the right bacteria dominant.

Added Stability. If it does what they claim (big if) it is phenomenal. More stable, non sulpher fixing aerobes, anaerobes, and faculative anaerobes. It can't hurt.

Have noted that pruned tops of hornwort grow at least as fast as they did before pruning. Am getting rid of diatome covered stem bases.

The next time I do a dirt tank I will mix Stability right into the mud to inoculate it with non sulfur fixing bacs and avoid hydrogen sulfide. I'd also mix Fluorite Sand right into the mud, cap with nice PFS or, better yet, sandblasting glass beads. I'd also keep the water level low enough the plants could access some surface CO2 for a month.

Parameters are stable. Nitrate seems to sit around 10ppm. True algae is all gone. Some diatomes persist. There is a small but growing patch of BG algae on the substrate which looks really cool; like grass. I don't know why they dont eat it. Both fish now sleep much more than before. I don't know why.

Hmm, sleeping fish.....what temp is your tank, how much aeration? I see you added a bubbler...is that the only one?

I have been outta the loop! Sounds like your tank is growing well. Any chance you can tank a full tank shot, id love to see it!!

Good call! I forgot, but I have been keeping this tank unheated which works out to at least ten degrees below optimum. That's why they are sleeping more... no doubt. The tank has tons of O2 because of the overflow. The bubbler is there to keep the CO2 from dropping below atmospheric levels.

I will try to post a pic tomorrow, but there's no big change. Almost all of the growth is very slow due to my ultra low light. Though the Fluviatilis Myaca (sp. ?) grows like wildfire.

no algae left except diatomes. perhaps my substrate leaches silicates???

I think i get diatomes, i noticed if i have my second bulb on i grow them in a few days time, so i only have the second bulb on for a few hours every other day or so....
