How big are your tanks and what kinds of fish do u have?

I'll PM you or find my thread in the freshwater members tank showcase section under "Caleb's tanks"

What about putting a betta in a community tank? 1 male guppy, 2 platys, 1 Molly, 2 Cory cats, 3 glow fish, and 1 dwarf gourami.

The betta would have problems with the DG and the guppy. Possibly the platy cuz it's so brightly colored.
 
What about algae in a tank?? My tank has a reddish brown algae starting to be everywhere. Its on the plants, the gravel, and the filter intake. Not thick tho, just lightly. Its starting to give everything that reddish brown color. Any way to stop it or get rid of it? Is algae good or bad?

It's harmless it's beneficial bacteria but don't let it get to bad or ammonia spikes can happen.

Sounds more like diatoms then some bacteria??
Many new tanks go through this so just wait it out.
The diatoms are supposed to eat themselves out of house and home.
Time line is hard but could be a month easy IMO.
 
Well I've had the tank set up for about 2 months.

When I do PWC should I rinse and scrub the plants and decorations?

Diatoms are cool looking under a microscope! I actually have the same thing happening in my tank but mine has been established for 8 months if not more, I think it's due to tap water.

Yea I think that's my issue too. I use the dechlorinator when I do PWC. What should the average Ph be in a community tank like mine?

pH doesn't matter as long as it's between 6.5-8.5 unless you are a breeder or keeping African cichlids.

OK so the ammonia levels are all I really need to worry about

Sent from my XT1019 using Aquarium Advice mobile app
 
I know ammonia should be zero or close to it but what about nitrites and nitrates?

Sent from my XT1019 using Aquarium Advice mobile app
 
Also what do nitrites and nitrates mean? How do u fix it if they're too high or low.

Obviously we need a little lesson on the nitrogen cycle...

I use this for social media hope it clears some things up:

What is cycling? Cycling is short the Nitrogen Cycle. Basically, bacteria live in your tank, they are what consumes waste so it doesn't become toxic and harm your fish. But your filter does not just "come with bacteria" right out of the box! This is where cycling comes in.

Why is cycling important? Many people have said "well I didn't cycle and my fish are just fine!" Well that's because most of those people have very hardy fish like bettas, guppies, etc, they can rough it through a cycle without issue.

Where does bacteria live? Let's make this really simple: 97%=filter 2%=substrate 1% water, decor, and plants. Basically, your filter is the home of all the bacteria you care about.

Where does bacteria come from and how do I grow it? This is the miracle of nature and science. I can't tell you specifically "where" bacteria comes from, only because I don't know. What I do now is how to grow bacteria, otherwise known is cycling a tank.

What you need to cycle a tank:
1. LIQUID test kit- I will stress this till the day I die. Test strips are junk. Liquid looks expensive but in reality you save a bunch of money because it can do 200+ tests for $10 more than a 25 pack of strips. I mean who wouldn't snag that deal?? You MUST have a test kit that you can get actual numbers from or else cycling will be near impossible without trips to the store for them to do it.

2. An ammonia source. This can be produced in a variety of ways. Fish obviously is the first method, this is the path of FISH-IN cycling. Simple right? Other sources include 10% grade ammonia from the hardware store, this is only a couple bucks. You can use uncooked shrimp from the grocery store and put it in a pantyhose so it doesn't make a mess. Or plain fish food is fine too but not as effective sometimes. These sources are used for a FISHLESS cycle.

Why do we need an ammonia source? This is what begins cycling. Ammonia is what feeds your bacteria to where they can reproduce and allows you to continue through the nitrogen cycle.

Enough questions let's get on with it:

Fishless cycling: this is really easy method, but you have an empty tank. On the flip side, you can do whatever adjustments you want to it so when you get fish it's perfect. If you are dosing ammonia by the bottle: shoot for 3ppm-4ppm. Google can provide a dosing calculator so you can know just how much to dose for your tank size. If you are using a table shrimp, just throw it in, it will naturally boost the ammonia and you just add a new shrimp when the other has decomposed. Now you want to use your test kit to measure how much ammonia you need to dose, it's simple math once you know how much makes 3ppm.

Fish-in cycling: This is where it can get tricky. Because you have fish you need to keep them safe. During a cycle, this will require daily testing and quite possibly daily water changes. You want to keep ammonia under 1ppm and nitrite under 0.50ppm if possible as both are highly toxic to fish.

Both cycles: in the beginning you will see ammonia start to rise, over time, the bacteria will overcome this and in a fishless you will need to start dosing daily(bottled ammonia) as time goes on. From there you will move to nitrites. Once you hit nitrites this is the longest phase. One day you will wake up and nitrites will be gone and you will be left with nitrAtes. Nitrates is the final product of the nitrogen cycle and is non toxic in lower levels. This is then removed through your weekly water changes.

Once the cycle is completed you should not see any signs on ammonia and nitrites, because now your tank is cycled.

Bacterial supplements: please understand these are a game of chance. They don't always work, sometimes they do nothing. Just know, I have NEVER seen one of these fully complete a cycle, only give a jump start. Please keep that in mind that just because you dump a bottle in doesn't mean your tank cycled..
