Increase Oxygen

Here I've listed 5 simple ways to help increase oxygen levels in an aquarium.

#1 Lower Water Level. Try not to fill your aquarium all the way to the brim with water, as water drops down into the aquarium (waterfall effect) from the filter it forces water down into the aquarium and helps push oxygen into the water thus helping to increase oxygen levels (be sure the current is not too strong for the aquariums inhabitants).

#2 Water Changes. Too many water chemicals and/or waste, etc can cause a loss of oxygen in the water, it's very important to do regular water changes (clean tap water contains adequate amounts of oxygen).

#3 Lower Temperature. Cooler temperatures can hold more oxygen than warmer temperatures but, be sure the aquarium is the proper temperature for the aquariums inhabitants.

#4 Air Diffusers, Bubblers, etc. With these devices attached to an air pump it helps to increase oxygen and water movement in an aquarium.

Air Diffuser

* Bubbles should be tiny (almost pin hole size) looking for the most part, and probably vary in size. The tank should not just have large (about a cm) and/or slow moving bubbles as this may mean your water has become thickened by dirty water. Also be sure your air pump is strong enough to operate the equipment properly, and clean or replace old diffusers, tubing, and check valves as needed.

#5 Filtration. The right amount of filtration is key to keeping a healthy and clean aquarium, you want to make sure the tank is not overstocked with fish either as the fish will be competing for oxygen. Keep filter cartridges clean, and active carbon can help remove unwanted chemicals and aid in oxygen levels.

Treating Ich on Ranchu

This past week I made a big mistake thinking that my ranchu would be fine in a temporary bucket of water while I cleaned out the aquarium. Well, it took me awhile to get around to actually cleaning my tank so I transferred my ranchu into a new bucket of water and they ended up going through a drastic temperature change (ranchu can only handle around a 3-5F temperature change at time) and thus suffered from it. Bumblez is not at all a fan of cold water and thus he began slowing down his swimming, while Oakki had broke-out in ich on the front of his wen. Luckily I was able to remedy both of them at the same time, here's how I cured and treated the ich in under 3 days (be sure to treat ich ASAP)...

1: Do at least a 50% water change to the aquarium water (be sure the new water added in is within 3-5F of the current tank water temperature), and treat the water with Seachem Prime according to directions (Seachem Prime helps reduce stress, helps slime coating, and dechlorinates water).

2: Keep the water temp in the aquarium around 74-76F (I use an Aqueon heater), as this seems to be an ideal temperature for ranchu in general.

3: Add 1-TBSP of Aquarium Salt (I used the Jungle brand) per 8-10 gallons of water (aquarium salt reduces stress, provides electrolytes, and cleans.. it may also raise your pH so be sure to dose accordingly). Although it may not be necessary, I added in a pinch of aquarium salt everyday after this initial dose until my ranchu no longer showed signs of ich.

4: Turn off any aquarium lighting to reduce any stress caused by glare, etc as these fish have already undergone enough stress at this point.

5: Be sure to run an air diffuser in your aquarium (along with a 24/hr running filtration system) for at least several hours a day to insure the fish are getting plenty of oxygen in the water (this is very important if you are using any other water treatments to remedy your fish outside of what I have on this post), this is especially important for smaller aquariums and/or ones with a higher temperature.

I hope my ranchu ich remedy works for others just as well as it did for my ranchu, and be sure to do another 50% water change a few days after having done the first one as to reduce the risk of having ich spread, etc (just be sure the new water you're adding into your aquarium is in the ideal temperature range as I mentioned before, too drastic a change may only worsen or cause the ich to reoccur). Good/adequate water quality can solve a lot of problems (be sure ammonia levels are also in a safe range, preferably no traces of ammonia, this is especially important if you have a small or overcrowded aquarium).
