We have a basement bathroom with a shower and use a couple of adapters to go from a diverter off the showerhead to a garden hose. This is a much simpler method of achieving this than going from water source -> holding tank -> pump. You are pulling straight from the main water supply and your...
Food being the source of bloat is IMO mostly overdone. As long as you are feeding something generally suitable for cichlids...
We have had good success treating with Metronidazole and using the Cichlid-forum recipe of relatively high Metro doses and 50% daily water changes for about a week.
We have found that is a very important to have the fry initially go into tank water - not even something very close to tank water. We will literally fill the fry tank with water from tank they came from. After a half week or so they can tolerate a water change without issues we find, but those...
Outside of Winter this is not very worrying in the short term. The tank temp is unlikely to fall below 70 or so very quickly and the Mbuna are fine with that if a bit slow moving. Keep the tank oxygenated (and even that isn't a worry for a few hours at least) and they will be fine.
The...
Just some real world experience...
On my 125ish gallon acrylic tank (72x18x21) with acrylic tops I found a single 250w heater to be inadequate. While it kept the temp at 79F it was basically on all the time, so I added another 125w heater and it is fine.
I found a similar story on my 120g...
We tried Purigen for a while in our cannisters, it was certainly absorbing something (and is easy to clean with bleach) but it never seemed to absorb enough to really make a difference.
There are three avenues for reducing Nitrate that seem to me to have some vague, though likely long-term...
Read up on them on the reef forums, it seems like most people using them buy a largeish supply and periodically run them through a washing machine either with no detergent or with bleach.
I find the reef forums are generally the best place to get sump information, they are just much more...
We have a Vortex D-1 which is a DE filter. It is exceptionally good at water polishing. That said we don't use it all that often...I don't think I would get one for anything other than water polishing.
We have done this a few times and here is what we have found...
Moving small amounts of filter media helps, but not immensely. In an established tank I think the substrate and rocks/plants/etc. all harbor surprisingly large amounts of bacteria. So moving some filter media helps seed...
Saltwater folks have a good guide for really detailed heater sizing if you are interested...

If you are not on well water you might want to try and find a water quality report which to see what the local water company thinks it is sending you...
I use the Jehmco temperature controller, which has a generally very good reputations.
Full reef controllers are IMO largely overkill for freshwater tanks, we generally do not have the type of equipment that allows fine control over the tank parameters these are designed to provide.
May be more light than you want, but we really like using Zoo med:
Flora (5k looks pink on its own)
Daylight 6.7k
Ocean Sun 10k
As a combo on T5HO triple fixtures.
While they are pricey ($80 or so), I relay like the Jehmco temperature controllers, they are easy to use and (by reputation from both the reef world as well as other real world applications - including I understand running commercial refrigerators and brewing beer) they are thought to be...
I have a 300w Eheim heater and just a word of warning....it is huge like the biggest heater you have ever seen. It will NOT fit vertically in a 21" tank...It will however, heat the heck out of your water which is why I have it, I needed it the one time I had ick and needed get the water up into...
There are four 1.5" (or so) holes two in each corner to run the canister tubing and power cords.
We have sumps on our other big tanks but have decided to not do that again. We are reasonably happy with the sumps and have them pretty quiet - BUT we find that sumps are not very fry friendly so...
