I guess for first tanks, start kits seems like the easiest way to go. From my experience to save some money are (although with this hobby, you can't save that much money, haha) to buy the tank during the Petco sale, and buy all the equipment online (Amazon is a good place).

So if you buy each part separately:

$29 = 29G tank -Petco

$10 = Heater -Amazon

$15 = Whisper 30 -Amazon

$15 = [DIY Sliding Aquarium Top] (

$69 = Total

Not much more expensive than the kit. The 29G comes with a mail in rebate that I'm don't know if it works with your purchases online or not. If it works, you'll get back $10 for the filter and $4 for the heater. Bringing your total to $55.

I would actually buy a more powerful filter than the one included. Probably one rated for two times stronger. A lot of people like aquaclear filters - I don't have personal experience with it but I will buy one next time I need a filter.

You're going to need stronger lights anyways, so I didn't include the light costs.

This is just my opinion! You can do what you'd like for your tank :)

I use a syphon hose. Right here on amazon

I would like to add that I live in Spokane,WA. And use tap water every time.

After every water change I treat my water with Stress Coat

I own 1 Oscar, 1 Red Jewel Cichlid, 1 Convict and 1 Pleco in my 75g.

As far as moving the fish, nothing changes when you go bigger. The steps listed above are perfect. My best advice is, if the fish store can hold the fish for you until you set up your tank at home, do that. Other than that you're just at a race against time from the moment the fish go into the bags. You benefit from being close to your LFS, so don't worry! And post pics when its done!

I know it depends on the type of fish you have, but a slow increase won't be a problem. My temp is that high in the winter and in summer down to something like 7.4. Be careful with pH down as that can create wide swings. I used it many many years ago, but now wouldn't. If you can, this product works great for me.

Don't know what size tank you have. But, I think I've used about a golf ball sized amount in a mesh bag or pantyhose for maybe a 10 gallon tank. To have a quicker effect, I've added two, but be careful, it may drop too quickly.

Relax, I think you're ok. The "chemical" look on the water surface is probably just bio-film. See this thread for suggestions:

Have you tested your water's pH, ammonia, nitrites, and nitrates? If not, get a test kit like this: Post your results here for advice. But I'm guessing that two 50% water changes every week is more than you need. You can probably cut that back to once a week or once every two weeks. That's assuming your levels are ok and your filter is working as it should.

Based on your photos, I'm guessing your tank is pretty new? The spots of algae on the rocks look like the beginning algae I've seen in newer aquariums. Same for the brown spots on the anubias. Treating your tank with Flourish Excel might help with the algae: Or, if your water chemistry tests come back ok, you can get a small shrimp or two to help clean up the algae. You want to make sure your water chemistry is ok for shrimp. Do a little research before you buy any. You don't say how big your tank is, but it can probably take a small shrimp or two.

If the old tank has a filter. Take some media from that filter and add it to your new tanks filter. This will add beneficial bacteria (nitrobacter)

You can also add bottled beneficial bacteria to help speed up the cycling process.
(I’ll add links below.)

So with the new tank cycling.

Do a water test on the old tanks water.
Ideal water parameters are
Ph 6.5/7.5ppm
Ammonia 0ppm
Nitrite 0ppm
Nitrate 0.5/15ppm
(Water changes for cleansing water of nitrates)
(0ppm ammonia 0ppm nitrite is a cycled tank)

Going on the fish is still alive. You’re just dealing with a dirty tank.. test the water conditions and let us know :)

Tetra Filter Active 250ml

API 800 Test Freshwater Aquarium Water Master Test Kit

Master test kit might seems expensive but strips are not reliable. And purchasing separate tests costs more. Far more cost effective purchase.

Our aquaclear is great. If you don't have the funds for a canister filter, and if you plan on keeping/breeding small fish/animals like shrimp you can fit a Fluval Edge prefilter sponge on the intake so you won't have to worry about 'accidents'.

If you're going full-planted, you may consider taking out the activated carbon from the filter and substituting it for filter fiber or similar media, as I've read in some places the activated carbon will get rid of beneficial bacteria.

Get one of these: 25 Foot - Python No Spill Clean and Fill Aquarium Maintenance System

You need to treat the water as it goes in, though. Once the tank is established and you do smaller water changes, I usually put the chemicals in as I'm filling from the tap. But I know the parameters of our tap water and know exactly what will need to go in as far as pH balancing etc.

The main thing is really just to monitor everything closely. Check the water from your tap before you move the tank. The nice thing about the python is that it aerates the water so that there isn't as much chlorine before it hits the tank. But you still need to add a water conditioner (I like Seachem Prime).

For the first adding of water, you want to preserve as much of the microscopic flora and fauna as possible. In my original comment I didn't add this, but don't scrub the tank or remove the sand if you can because colonies of beneficial bacteria live there. And then slowly add water of the proper temperature and acclimate your fish as slowly as possible.

The Aquaclear 20 is probably the best HOB for that sized tank that I've ever found. I clean it about once a month, but I never change the sponge or bio media, just rinse them out in tank water during water changes. I also have an Aquaclear 70 (same filter but bigger) on a 40 gallon thats ~15 years old and still going strong.

u/Confidence_Trickster · 2 pointsr/aquarium

I actually never do that, I always think it just makes the fish stressed out. Here's my routine:

  1. I use a mini siphon to take out 25% of the water

  2. Dump out the bucket I put the dirty water in, and rinse it out, then put new, clean water in with some dechlorinator. I use Prime. I always just use my hand to feel that the water is close to the same temperature as what's already in my aquarium.

  3. Very slowly pour the new, clean, dechlorinated water into the tank.

  4. That's it! I always double check my filter to make sure it's not too gunked up, and clean that as necessary, but that's usually like once a month or less.
u/WhoaBuddyxD · 3 pointsr/aquarium

As far as equipment goes, get an AquaClear 20 (or 30) filter, an Aqueon (or other reliable brand, I've used Hydor with good luck) ADJUSTABLE heater. A thermometer. The lights you get depends on what you plan on doing with your tank. You're also going to need a water testing kit, a dechlorinator (most people will recommend Seachem Prime).

Is this going to be your first aquarium?

u/wijnandsj · 3 pointsr/aquarium


Yes I am being serious. Goldfish are messy fish, they require an active owner.

u/ashleyasinwilliams · 7 pointsr/aquarium

Looks like a gourami? It would help if you could post more info about the tank. How long has it been set up? What exactly is wrong with the fish? How long has he been sick? Anything wrong with the other fish? The biggest thing is if you could please test the water to find out the ammonia, nitrite and nitrate (you can test with one of these, they're commonly available at the majority of pet stores or online). Also 10 gallons is pretty on the small side for these kinds of fish.

Take a look at the [Penn Plax Cascade 1000]( CCF3UL Canister Filter, 100 Gallon, 265gph I have two of them and they've served me well for over a year.

u/catdog743 · 1 pointr/aquarium

You might consider changing to a canister filter. It will remove tons more waste. Amazon has some cheap ones that are actually very good.
Lots of people with turtles in the comments on this one
Cascade CCF3UL Canister Filter, 100 Gallon, 265gph

Can also use polyester fiberfill or quilt batting and make/cut your own filters.

u/CompanywideRateIncr · 1 pointr/aquarium

Man, I was all set to get a nicrew but now that I'm about to pull the trigger I can't stop looking at this thing lol. I think I'm gonna get this for one of my 20s and put it on my 30 when I upgrade.

u/TheLastBearOfCali · 2 pointsr/aquarium

If you can't find one pre-made for your tank size then you can go to a local glass shop and they can make you one. Shouldn't cost too much.
