That’s SOME Algae Growth

SOME algae growth

It has been almost a year since I set up my freshwater tank. At the time, N told me that all of the work happens at the beginning and once the tank is cycled and planted and full of creatures, it’ll just take care of itself.

I’ve found that to be mostly true. When I was setting it up, I was a little concerned about performing weekly water changes. I’ve found that they are actually not a big deal. I’ve also found that my water parameters have been great, even if I miss a weekly water change.

Right now the tank has one pearl gourami (female), 4 neon tetras (I started with 8: 1 died, 3 disappeared), 6 black kuhli loaches, 5 amano shrimp, and 1 albino bristlenose plecostomus. I’d like to get a few more shrimp, some more tetras, and maybe another bunch of small shoaling fish. I’d also like to add some more plants and rearrange some things. Overall though, it’s been nice to have a tank of fish.

The algae growth is from the weeks we were away from town. Before we went on vacation I did a huge (75%) water change and cleaned out the algae. Our fabulous petsitter fed the fish as requested and we came home to tanks in great shape — I just had a lot of algae growth. 0 ammonia, nitrite, and nitrate levels. Yay science.

Fishin’

I vacationed in southwest Florida last month. As always, we did a lot of fishing while we were there. We caught quite the collection. Among the sea creatures we caught were sheepshead, speckled sea trout, redfish, flounder, grouper, snapper, lizardfish, ladyfish, snakefish, scalloped hammerhead sharks, and a stingray. Not bad!

damn fish

…and a few hardhead catfish.

Saltwater catfish are a bit different than their freshwater brethren.

A hardhead catfish stuck me with one of his barbels while I was trying to unhook him to return to the water. He was really small and I had my fingers in his mouth as I wrestled with the barbed hook — he swung his backside around and got me in the palm.

The slime they are covered in is poisonous, and getting it into the puncture from the barbel can be a very bad thing. I squeezed my hand to make a lot of blood run out to clean the wound, rinsed it off in the saltwater, then used hydrogen peroxide and triple antibiotic ointment on the puncture when I got home from fishing. It looked like it was healing fine until a WEEK later when it got really itchy and inflamed. I punctured it with a needle shortly after this photo was taken. Now it seems to be fine, though there’s still a little spot there.

One of the fishing books I was reading to identify fish on our trip actually said not to touch these fish at all, to just club them. Of the ten or so that we caught this trip, only one of them punctured me — I catch them every trip down there and this was the first one EVER that managed to puncture me. Just be cautious and know that they have barbels. No sense in killing them for no reason. They are fun to catch and they are useful scavengers.

Today’s shot, just a quick one when I ran out to work from the library.

I love this tree though.

Ick, Ich!

After about a week, I noticed a tiny white spot on one of my neon tetras. Oh, crap. Ichthyophthirius multifilis or Ich or or Ick or White Spot Disease.

Ich isn’t actually a disease, it’s a parasite that attaches to fish when they are stressed. Like say, when they go to a new home. Or when the heaterstat fails and the temperature drops 4°F overnight. Or when the pH jumps from 7.2 to 7.5 overnight.

poor tetras

I spied 4 tetras with super tiny spots, smaller even than a grain of salt. It fluoresces under the blacklight. I did some quick research and raised the temperature in my tank from 74°F to 86°F over the course of 24 hours. I did a 50% water change. After 24 hours, I’m only seeing 1 fish that still has white spots.

I will continue to keep the temperature above 86°F and will perform daily 50% water changes until it has been two weeks since the day I don’t see any more white spots on the fish. Here’s hoping it works! Poor fish. They are acting alright so far, though.

New Tank

Fishkeeping is a funny hobby. It’s infectious. While I worked on setting up my freshwater planted community tank, N had the urge to start up a marine reef tank again.

On Christmas Eve, we got up at 5am and drove down to the airport to pick up three boxes of live rock and sand.

We arrived home and N worked quickly to get the live sand and rock into his 29 gallon tank. Fairly quickly a bunch of hitchhikers showed themselves:

It's a hermit crab!

The tank is still cycling now. We’re working on capturing a few unsavory characters — a gorilla crab and a bunch of whelks. There are a couple of fish in it now, a blue devil damsel and a domino damsel.

Tank Layout

The day after Christmas, I checked my water parameters. I was shocked to see that while my ammonia and nitrite were still at 0ppm, my nitrate levels had dropped from 10ppm to 0ppm. I have a fairly heavily planted tank so it’s not beyond the realm of possibility that my plants are managing the nitrates for me.

I need a bit more plants in front, between the rainbow rock and the lava rock. I’m thinking about some java moss.

Stocked

Last week my tank finally finished cycling on Monday — I was shocked to check my nitrite levels and see that they were down at 0! I did a 50% water change and added more plants — an amazon sword, a green ozelot, some grasses, and some rotala macranda.

That evening, after the tank had settled down, I finally picked up some fish.

I got 8 neon tetras and 1 albino bristlenose pleco. I wanted a non-albino bristlenose, but they didn’t have any.

The pleco is pretty awesome.

Fishless Cycling & Planaria

I noticed fairly early on that I was getting some weird white spots on the inside of my fish tank that looked like water spots. Except that of course water spots on the inside under the water level didn’t make much sense.

planaria

In browsing fish forums, I discovered that planaria thrive on high ammonia levels. They are a sign that you have an ammonia problem if you have a stocked tank (good to know!). If you are like me and are cycling a fish tank without fish by using household ammonia, then they pop up during the time that the nitrosomonas bacteria is building up. They will stick around through the fishless cycle because you keep adding ammonia to the tank to keep the nitrosomonas bacteria from dying off while waiting for the nitrobacter to build up. They don’t mention this in any of the fishless cycle tutorials!

The good thing about planaria is that they will die off when the ammonia source goes away. Also many fish like to eat them. They are fairly harmless.

First Week Or So

In the first week of fishless cycling, I’ve seen my ammonia drop off, my nitrites go off the chart, and my nitrates start to register. All good things!

On Saturday I was checking my ammonia level, which was at the same level as it was on Friday. Due to this, I wasn’t going to check my nitrites or nitrates. N suggested I check both nitrites and nitrates anyway, so I did.

Sure enough, on Saturday I was registering a lot of ammonia — 3-4ppm. I was also registering 2+ppm of nitrites and just barely registering some nitrates. Woo!

Sunday I checked all three again, and my ammonia was about the same, but my nitrites were off the chart (>5ppm) and my nitrates were above 5ppm.

– indicates no reading taken

Today my ammonia was fully processed to 0ppm in under 24 hours! My nitrites are still off the chart but my nitrates are growing (or at least staying put).

I added 2mL of 10% ammonia to the tank to ensure that the nitrosomonas don’t die off with nothing to oxidize. Now I am just waiting for more nitrobacter to develop to handle this massive quantity of nitrite. Once we get the nitrite spike down to 0, we will do a 50% water change and finally stock with fish.

At the Start

In order to start my fishless cycle of our aquarium (nitrogen cycle), I did a few things.

First, I planted a handful of plants that I bought at the local fish shop. Plants carry some beneficial bacteria on them and they also help manage nitrates. They also tend to survive alright despite the currently changing water conditions. We’re not done adding plants yet and my ozelot sword is looking pretty sad right now so I am a little loath to add more plants just yet.

With just the plants, rocks, driftwood, and substrate, I was registering tiny amounts of ammonia, but not enough to get the tank started.

After a day or two, I added some household ammonia (without surfectants or fragrance — if it’s yellow, scented, or bubbles when you shake it, DO NOT USE IT in your tank). The nitrosomonas need ammonia in order to develop and then oxidize the ammonia to turn it to nitrites.

I sort of winged it on the ammonia — I added 5mL of 10% ammonia solution to our 29 gallon biocube and after it had processed a couple of times through the filter (to disperse throughout the water) and tested the ammonia level, which was around 4ppm — thankfully the target.

I started testing ammonia every day. Until the ammonia starts to drop, there was not much of a reason to test the nitrite levels. Tomorrow I’ll post a chart showing the levels for the first week.

pH is still fluctuating due to the substrate, ammonia level, and tannins given off by the driftwood (despite boiling for a while, it is giving off some tannins). I will probably test pH weekly though.

Patience!

Fish Tank Cycling

Before we made the decision to get an aquarium for the house, I started reading up on the process. While I kept a freshwater tank as a kid, I had very little recollection of how we set up the tank initially and I knew that was the important part.

In reading about getting a tank ready for fish, I read about fishless cycling.

testing
testing – at the beginning

It seems to be a more recently popular process for cycling a tank. Instead of stocking a tank with a couple of fish whose excrement produce ammonia, you can add household ammonia (with no surfectant or fragrance) instead. This prevents the fish from being subjected to high levels of ammonia and nitrites while the bacteria multiplies.

N was skeptical, having always cycled tanks with fish. It made sense to me though, so I started a fishless cycle.
