Minor Improvement, Elevated KH

There seems to be a minor improvement in the "carbonated" look the 150-gallon has had. The bubbles are still present but not so many. I also tested my KH and found it to be 8, which is much higher than typical (4) and the tap is higher than usual as well at 6, though not as high as the 150.

I don't particularly mind higher KH, as it lends stability to pH, but I think it is time to remove the calciferous rock I placed in the tank a few months ago to deal with an almost unmeasurable KH - it took only one drop to turn the solution yellow/orange, and it seemed like it was turning even before the full drop was dissipated, which I would call a value of <1 degree KH. I did not like that and am not sure at all why it was the case. Tap, at that time, measured solid 4 dKH. I think perhaps the tap KH may rise in the summer versus winter, but I will have to measure this over a period of years to see if there is a pattern.

When I talk to the water treatment people they deny that there is any fluctuations and they seem to read from a script when answering questions. I don't think they understand the purpose behind my questions, but rather are automatically defensive when discussing the quality of water with their customers. Nobody I have spoken to can relate to an aquarist manipulating pH and trying to have an understanding of the chemical makeup of tap water.

I recognize, too, that I ought to be using RO water and treating it ahead of time, getting the values I desire before it goes into my tank. However, I am just not interested in keeping 30-gallon tubs of water in m living room. It is not practical. I don't keep a fish room, but instead my aquariums are living art that are part of how I decorate my living space. If I had a basement I might consider setting up a mini water treatment plant, but I don't, and my home is spacious but lacks any kind of utility space or storage space.

So, I can't keep delicate species but am trying to compromise when it comes to the P. leopoldi. I don't think my chances of them breeding are very high in this setup, but I am okay with that right now. I would like to be able to drop the pH and raise the CO2 concentration, as this has helped immeasurably in keeping algae at bay, and I have been able to do that for years in this and other tanks, so my current issues with pH and CO2 are puzzling. Mainly, I find the bubbles annoying!

Agnes & Frank 'n Fry



Here are pics of the breeding angels in the 40-gallon.

The plants in this tank have grown markedly in the past few weeks, I am assuming from the extra nutrients provided by the fry and the frequent feedings. The fry are numerous and all look like miniature angels, with ventral fins and all. Most appear to be marble, but they may wind up being silver if the striations consolidate into stripes.



Here is one of Agnes, and though the fry do not show up very well they are literally everywhere in this pic if you look closely.

They have turned out to be most excellent parents, and will bite you if they can when you put a hand in the tank. They attack the glass when you approach, and I am very pleased with how well they are handling their job.

I do believe I will pull the next batch of eggs and give them a break. They have spent so much time tending eggs and looking after fry, most of that time spent with lights on 24/7, that I feel they need a break. It must be a strain on them physically. I do try to keep their diet varied and high quality. I do daily PWCs on this tank.

Carbonation!

So the latest news is that the female Ancistrus has not expired, and I have seen her recently. She does not look that different but maybe perhaps a little less rotund. Not so much like a Weebil anymore....

Also, the 150-gallon tank appears to be full of carbonated water. There are tiny bubbles everywhere. This is not a case of excess waste that can contribute to a collection of filmy bubbles at the top of the tank on the surface, but this is in the water column. I did a big PWC after I found the dead cory (see below) and moved the CO2 diffuser into a less visible location, which was next to the intake for the Fluval XF5. It could be nothing more than the bubbles collecting in the filter and being dispersed, though the quantity of bubbles seems excessive.

I am, at the same time, having trouble getting my pH to drop with CO2. It would typically run for a while and then shut off, and turn back on only when the pH crept up past 6.4, but now it has to run all the time, and I can scarcely get it below 6.9. Not sure about that, other than that my tap water is moderately hard and alkaline (buffered) and this recent PWC sent the KH and GH up (possibly, did not test), making it difficult to manipulate pH with acid. That seems like a stretch but my chemistry is rusty. I have added more Indian almond leaves, which ought to contribute to lowering pH but no dice. Incidentally, I did calibrate my pH sensor and it was not off at all - it was exactly correct.

So, the tank looks cloudy with the tiny bubbles. The fish are acting normally. The tank used to be rather clear prior to this episode.

I have also fixed my old Rena Filstar XP4 that I had running on the 55 prior to getting the 150, and got some new tubing for it, and have started that running on the 150 as well in case that will assist with resolving the bubbles issue. It mainly has mechanical filtration to remove fine particles and we will see if that helps. There is right much water movement in this tank, which is not necessarily what the leopoldi would prefer, but it seemed like I was not getting adequate turnover with the FX5. This is likely my imagination, since the thing is the size of a large Shop Vac and must be blasting water in and out. I thought there was too much debris not getting filtered out.

Updates and Additions

I added 8 more C. trilineatus to my group of what I think must be 6-7 in the 150-gallon tank. The school hides so effectively and often that I go for days or a week at a time without seeing them. I am hoping these new guys will coax the rest out. The new ones are very small - almost half the size of the adults I have in residence. Almost a day later it does not appear to be working, but we shall see....

Also, I am dismayed to see that my female Ancistrus has some sort of bloat. Her belly is distended and she is on the sand, poised atop the belly so that her mouth does not quite reach the sand when resting so. I have been feeding zucchini and romaine, along with veggie wafers, but the bristlenoses do not seem terribly interested in them. I have put bell pepper in there from time to time as well with minimal attention by the catfish. The snails enjoy these offerings, however.

I am assuming she is not going to pull through but I have been unable to catch her, even to put her in another tank on her own to observe her. She will be out in the front and as soon as I approach she zips into the depths. I would have to dismantle the tank completely to be able to catch her and I am not willing to do that. More PWCs and hoping for the best.
