I have three tanks that have been up and running for 4-5 months now. In all three tanks I see signs of brown algae and in the 15-gallon there is green algae (not cyanobacteria) growing on the fake plants near the surface. I would like to fix any water quality problems that cause this and also...

I live in a small town and have only one very expensive option to buy fish supplies from. For this reason I tend to buy bulk online or whenever I’m in the city. Now I find myself wondering how long these products (and others) will last before expiration. Fish food – flake / freeze dried. (I...

I got a question that I hope isn't too far off topic. How do you test your oxygen and co2 levels with out waiting to see which struggles first, your plants or your fish.

Larry, I am by no means an expert on anything fish but one thing you might want to conceder is a bad batch of guppies. I added 10 swords to my 90 and am now down to 1. All the other fish that are in the tank (angels, corys, tetras and a pleco) are fine. I went back to my LFS and found that most...

I cycled my 90 gallon tank using the same method of ammonia and a small amount of seeded media. I took 2 weeks for ammonia to start to drop and 3 for the nitrites. After a month I had readings that I deemed acceptable. One thing I’ve read (and I’m sure you have too) is to cut your daily ammonia...

Before this post I thought the neons and corys were good stocking choices for this tank because of there small size. I wanted to go with panda corys initially cause there even smaller then the albino/bronze but could find none. I know the corys should be in a group of a least 5-6 but at this...

I run a Rena 200 air pump and air stone in this tank because of the small surface area. Also the filter causes alot of surface movement so I don't think aeration is a problem.

Would you consider this tank over stocked? 15-Gallon Extra Tall, 13.5” Long X 13.5” Wide X 20” Tall. Walmart Aqua-Tech 20-40 Filter. No real plants. 9 X Neon tetras 2 X Albino Cory (Corydoras aeneus) The reason I ask is I would like to add 2-3 more corys to the mix but think I might be...

The python uses water and water pressure from your faucet to fill the tank. With out the faucet it can’t move any water to your tank. I simple turn of the valve at the bottom of the waterbed pump will change it from drain to fill. Maybe you could buy a submersible power head / water pump and...

I shelled out the cash for a 75” python and have been kicking my self ever since. It’s not that the produce doesn’t work; in reality it works great and is a time saving must. The problem was when I final got it in the mail and had a good look at it I realized I could have built the thing myself...

What you see there is the Bio-wheel pro 60 with the magnium canister included. I already have a XP3 canister and want to attach the bio-wheel to it. If I needed the magnium canister I would say thats a great deal.

I don’t run a UGF on any of my tanks so the way I see it, the cleaner the gravel the better. With this in mind when I do my weekly water changes I vacuum relentlessly. Once about 30% of the water has been removed only 25% of the gravel has been properly cleaned. I would like to be able to clean...

Well I would hope it would be clean but the extra wet/dry filtering wouldn’t hurt right. I went and looked at one and now I’m not sure if it would be worth it. It looks like clearance will not be a problem but I encountered new ones. The intake on the 18” long pro 60 is right in the middle then...

I want to connect a Bio-Wheel Pro 60 to the outlet line of one of my XP3’s. I’m not sure if this is even possible and I already see some problems. My tank has 4” of clearance between the back of it and the wall and can’t be moved. Also I have a 3D wood background so the Bio-Wheel could only hang...

I want to set up a bare bones, no gravel, no decorations 10 Gallon tank for hospital, quarantine and breeding purposes. I’m wondering what size and type of filters would best suite those needs. Would it need to be aerated? Also I am unsure how one would maintain the nitrogen cycle when the tank...

Now I’m all worried about under filtration. I have two other aquarium specs I want to run past you all. On a 15 gallon tall (13.5”L x 13.5”W x 20”T) I have one Regent Aqua-Tech 20-40. On a 5.5 gallon I have one of the 5-15 models. These are a cheap brand of filter I bought at Walmart. There is...

Does ONE of these canisters provide enough filtration for a fully stocked 90 gallon tank? Or should I start saving for a second now?

Hi, I have a 15-gallon tall aquarium in my bedroom and my girlfriend figures that it needs bubbles in it. I told her it would be pointless and noisy but for aesthetic reasons she insisted. Anyway I went out and bought a 15” bendable bubble wall and am now looking for the smallest and quietest...

For reasons that would take to long to explain I have 3 angels and a pleco in a 15-gallon tank and 4 swordtails in a 90-gallon tank. I would like all these fish to trade homes within the next week. What I’m looking for is advice on the easiest, safest way to accomplish this. Both tanks are in...

It doesn’t appear to be spreading at all. In fact over the last few days it looks better. I started him on the recommended dosage of melafix yesterday and today he is active and seems his normal self. I’m not sure if he’ll eat yet as I’m going to wait till his normal feeding time tonight...

I have a Betta in a 5.5 gallon, filtered tank. About 3 weeks ago I added a heater to the tank and over the space of a few days brought the temp up to 79*F / 26*C. The Betta loves the heater, only a little too much. I found him wrapped around it on occasion and then noticed discoloration on this...

Ok so no neons. But what would be a hardy, unaggressive, smallish, schooling fish to add with angels? I think I'd like a large school of about 9-13.

Wouldn't neon's and cardinal's be small enough to be dinner for the angels?

I have a 90 gallon cycled tank that will soon be the home of 3 small angels and 1 pleco. I am looking for ideas on compatible tank mates for them. Maybe a school (9-10) of brightly coloured smallish (1-2”) fish would work? Or more angels? Or some kind of centrepiece fish? Also this move leaves...

So does that mean you dont know what it is.... Or you just think it was a stupid question?

I found the stuff in the pictures growing in my tank the last few days. It’s a very thin and transparent film of some kind. I would like to know if it’s algae or cyanobacteria (Blue-green, slime or smear algae) or something else. I am currently doing a fishless cycle in this tank so nitrate...

Hi again and thanks for the post, I’ve tried tilting it to help air out of the system. I’ve tried turning it of for different periods of time. I’ve changed the distance from it and the water level in the tank. I’ve emptied and completely re primed it. And I’ve checked and rechecked every...

I have just set up a Rena XP3 filter on my 90-gallon tank and it seems to be working fine with one exception. Every few minutes I can hear air going through the filter and then seconds later the air bar spits out millions of micro fine tiny bubbles. I find the bubbles make the water look cloudy...

I didn’t take into account that household ammonia is diluted to about 5-15% NH3. It took me 10 teaspoons in a 90-gallon tank to get the reading I was looking for. Thanks for all the help everyone.

I have two Regent Aqua-Tech waterfall style filters that I bought at Wal Mart. They are cartridge-based filters with all the media packed up in one little disposable unit. My question is, do I really want to change these things every 2-4 weeks like the package instructs? When water flow becomes...

If anyone is interested I solved this problem quite simply. I drilled out the holes on the spray bar to a slightly larger diameter. No more whistle.

Got a question for you all. I’m attempting a fishless cycle on a 90-gallon tank. I bought some Big Al’s brand cycle and a no name product simply called “pure ammonia” at my local grocery store. The ammonia did not have an ingredients list so at the store I pulled off lid and checked a few...

just got myself a Rena XP3 filter for my 90 gallon tank. I set it up as it says to in the instructions with one exception. One of the water lines was too short so I replaced it with a prefab Fluval hose with fittings on each end. The replacement hose was too long and could not be cut to size...
