Seachem Discus Buffer

Discus Buffer® helps to replicate the ideal Discus environment (low pH & low GH (General Hardness)). Discus Buffer® will lower pH and keep it lowered. Discus Buffer® also softens water by precipitating calcium and magnesium. Use Discus Trace™ to restore the proper level of trace elements and feed NutriDiet® Discus Flakes for thriving, healthy Discus.

Neutral Regulator® and Discus Buffer® can be used in combination to achieve a desired pH when performing water changes or adding top off water. The ratio chart below is designed for RO water where there is generally no buffering capacity.

Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to acid pH.

Directions

Use 1 level teaspoon (5 g) for every 40-80 L (10-20 US gallons) daily until intended pH is reached. Thereafter, use once a month or with water changes as required to maintain pH.For precise dosing use the Seachem Digital Spoon Scale. To raise pH, use Neutral Regulator®. To target a particular pH use in combination with Neutral Regulator® following the chart. This chart assumes the use of unbuffered water (RO or DI). If water is already buffered use the chart as a starting guide. Use Prime® to dechlorinate tap water before doing a water change.

A: Neutral Regulator® and Discus Buffer® are phosphate based buffers providing a very strong and stable buffering system. Alkaline Buffer™ and Acid Buffer™ are non-phosphate buffers, which although less stable than a phosphate buffer, are ideal for the planted aquarium where high phosphate levels would lead to an algae problem.

I have a fish only freshwater tank and need to lower my pH. I am afraid to use Discus Buffer™ because it contains phosphates. What should I do?

A: Phosphate is nothing to be concerned with in a fish only system. Phosphate concerns are a ‘carry over’ from reef keepers where even a small amount of phosphate can present problems for many corals. It is really an insignificant property in freshwater systems unless it is a planted tank with a very intense lighting system. If you are still concerned about phosphate causing algae problems in a fish-only tank, rest assured that phosphate in itself does not cause algae; algae requires light that is in the blue spectrum for photosynthesis. Standard aquarium light is weak in the blue spectrum and strong in the red range and does not easily support algae growth. This makes the colors on fish seem brighter. It also makes brown fish look more red.

What do I do if Discus Buffer™ makes my freshwater tank cloudy? How do I clear it up?

A: The cloudiness you experienced is caused by the precipitation of excess calcium and magnesium. In excessively hard water, the precipitation could cause a clouded or chalky hazed appearance. To clear this, you can use a water clarifier (flocculant) like our Clarity™. You could also wait for this precipitate to fall out of solution on it's own (fall to the bottom of the aquarium) but this would take considerably longer than using a flocculate. You can also use a fine mechanical filter (floss or micron) to catch these particles.

Is Discus Buffer™ safe to use in a planted aquarium?

A: Discus Buffer™ (phosphate based) is safe to use in a planted aquarium but bicarbonate based buffering systems are generally more accepted in planted aquariums as to not introduce any excess phosphate (which could cause unwanted algae growth). You can achieve a bicarbonate based buffering system with our Alkaline Buffer™ and Acid Buffer™.

I am interesting use Discus Trace™, but I just wonder what is the difference between Discus Trace™ and aquarium salt.

A: Common aquarium salt (sodium chloride) is used to impact the density of the water making it harder for parasites to equilibrate to the denser water. Some fish do not mind this therapeutic use of salt, and some fish do mind it. Discus are a fish that will not tolerate this elevated level of sodium in the water. If you keep live plants in your discus aquarium, the plants will not tolerate this either. Discus Trace™ is a well rounded trace mineral supplement that does not contain sodium and is used to replenish trace and ultra trace minerals that are demonstrated to be necessary for fish health and growth.

My favorite facial sunscreen
Size: 2.1 Fl Oz (Pack of 1)
I love this sunscreen mist for the face. I have tried many facial sunscreens to protect against the Arizona sun and this is by far the best. So many sunscreens have a heavy feel, make my face sweat more, and end up clogging my pores. This sunscreen has a light, pleasant smell and is a lightweight spray. You spray it into your hand and smooth it on your face and neck. It feels hydrating without any heavy or greasy feel, and you can use foundation over it if you wish. It has done a great job protecting my skin, and just as important for me, it does not clog my pores and cause complexion issues. I have pretty sensitive facial skin and this has not caused any irritation at all. It is definitely worth trying and then buying again when you love it.

Not great
Size: 2.1 Fl Oz (Pack of 1)
I wish I could give 3 1/2 starts but I have to give it 3 stars for two reasons. 1 is it is not a fine mist, it will leave your face looking crazy after you spray it. You end up having to pay it into your skin because there’s white splotches all over your face. So if you were to apply this with no mirror it would be a problem. Also I feel like it semi defeats the point of using a face spray if you have to use your hands to finish applying it. 2 is that for me it makes my skin feel hot and kinda burn around my mouth area. I think there might be too much fragrance or something. It does go away after awhile but it is not pleasant and I can’t imagine it is good for me.

Great for summer pool time
Size: 2.1 Fl Oz (Pack of 1)
Gave it 5 stars because it really does its job. I used this sunscreen on my face during the summer when I was going to the pool a lot. It goes on white at first, but once you rub it in well the white cast pretty much disappears. Doesn’t make my face super greasy and protected my skin really well, no burns, no weird tan lines, nothing, as long as I reapplied it like the instructions say. The smell is light and not annoying. The bottle is small and easy to keep in a bag. Overall, a good product that actually works.

Easy to use, and long-lasting sun protection
Size: 7 Fl Oz (Pack of 2)
Coppertone SPF 30 sunscreen is our go-to for the beach and pool. I also keep a bottle in the truck for when we're doing anything outdoors like tailgating and things of that nature. It's not greasy, it goes on easy, and works exactly as it should. We don't worry about sunburns with this stuff, and it seems to last just fine even after spending time in the water. I can put this on when we first go out onto the beach or the pool in the hot Carolinas sun, and I can spend hours out there without getting burned. I do reapply after a few hours if we're in and out of the water a lot or in the more intense sun further south like in the Caribbean. To be fair, part of what I like is the nostalgia of using the same brand that my mom slathered on us kids in the 1970's, lol, but in those days sun protection wasn't as important to us as a deep tan was, so we'd still burn. Modern day Coppertone makes sun protection their priority, and I don't know of a better sunscreen that's as easy to apply and lasts any longer than this one. Is it possible to get a tan while using this product? Sure, but it takes longer and that's fine - because I rarely burn at all when using it, and that's the whole point.
