On 9/13/08, I changed 2.5 gallons in the 12 gallon tank and 1 gallon in the 6 gallon tank. First, I sucked up some red planaria. Then, I used tweezers to remove some bubble algae. Then, I put the zooanthid rock in the bucket of dirty saltwater and yanked off more Caulerpa. I also removed the smaller piece of live rock and yanked Caulerpa off of it too. The hard green algae was scrapped off the front glass which is hard since it is curved glass. I had to forget clearing the left glass (I can also look in there to check on animals). The back and right glass I leave alone for the snails to chew on. I rinsed the sponge filter in the dirty water. I changed the mesh bags of RowaPhos and carbon. I added a new small mesh bag of aragonite to the filter in hopes of buffering the water better. I also sprinkled some around the tank as the sand bed was mostly small shells and not very deep. I plan to add a little each week for buffering and to keep the sand bed stable as aragonite dissolves over time and gets sucked out with water changes.
Soon after I finished with the two saltwater tanks, I noticed that the plastic skimmer intake had fallen off the 12 gallon filter intake which was strange. The pump was not pumping! I ran power from another line and still no pumping! With a lot of pulling, I got it out of there and took it apart. The drive shaft is metal! Metal plus saltwater equals corrosion. I scraped off some of the rust but it is not in good shape. I got the pump to work, then it did not, then it did, then it did not, and finally, it did and stayed on. This added half an hour to my 12 hours of chores. I will have to buy a back up pump (way overpriced) for both tanks. I am glad I bought a Koralia Nano pump that I was not sure if I needed. I may try to get a double extension cord so I can run it (I am out of plugs; I have 13 cords, half of those on extension cords, running 15 things plugged in to two power strips in a single double outlet!). If the main pump dies, I have that back up although it would not go through the filter chambers.
The water test results for the day were:
12 Gallon Tank: 79.0 degrees F, 1.024 SG, pH 7.98
6 Gallon Tank: 79.2 degrees F, 1.025 SG, pH 7.90
Make up water: 77.6 degrees F, 1.025 SG, pH 8.18
On 9/20/08, I did the usual maintenance. First, I sucked up some red planaria. There are a ton all over. I did not see any bubble algae (but later saw three so they did not get removed). I pulled more Caulerpa off of the zooanthids which are doing worse and worse thanks to the Caulerpa. I rinsed the filter sponges in the change water and put in 2.5 gallons of new water. Then, I took out the old pump which was barely working. Someone in the nano reef forum suggested that I get a Marineland Maxi Jet 900 which I did. It pumps 230 gph versus the pump that the tank came with which pumps 106 gph according to the place I got it but 900 L/hr (237 gph) according to the pump itself. The top broke off of the new Maxi Jet so I had to leave that off. I could only get the Maxi Jet in there one direction which is not the way it is supposed to go. It is supposed to be intake down and output up. I put it in sideways with the intake facing to the left. The heater sits on top of that (the suction cups do not suck) which is not good but I got it all jammed in there. The tubing from the tank does fit over the Maxi Jet but the tubing does not bend so that is another reason I had to lay the Maxi Jet on the bottom (instead of using suction cups) on its side. The water flow coming out is definitely more than the old pump which is good. I managed to get the grommets back over the cords for the heater and Maxi Jet as they exit the lid. I could not get the grommet on last week after removing the old pump so I ended up squishing the cord a few times putting dents in it. Everything in these nano cubes is so undersized and squished together! The 6 gallon is even worse. I have ordered a Maxi Jet for it as well.
The water test results for the day were:
12 Gallon Tank: 77.7 degrees F, 1.0235 SG, pH 7.94
6 Gallon Tank: 77.1 degrees F, 1.0245 SG, pH 8.16
Make up water: 77.6 degrees F, 1.025 SG, pH 8.47 (I do not know why it was so high since I
follow the same recipe for the saltwater every week; I used it anyway to help bring up the tanks'
pH)
As the new animals were coming, and water would be used for both acclimation and water changes, I decided to make up 5 gallons of saltwater for Saturday. That required making 3 gallons of RO water Thursday night and 2 more gallons on Friday night yielding almost 8 buckets (3 gallons each) of waste water (which I would use Saturday for Tator's 40 gallon tank in which I feed him). I made up the saltwater Saturday morning in two batches since it will not fit in one bucket.
Since the animals came at 9 am, I floated the bags in the tank while I went to the grocery store. About an hour later, I then set them up for drip acclimation which lasted 1.5 hours. Before starting, I measured the pH and specific gravity of the 6 and 12 gallon tanks and each of the bags of new animals. Here are the results using the pH meter and refractometer.
12 gallon tank - pH 7.89, SG 1.025
6 gallon tank - pH 7.99, SG 1.025
Bag with the green clown goby - pH 8.09, SG 1.021
Bag with sexy shrimp #1 - pH 8.07, SG 1.027
Bag with sexy shrimp #3 - pH 8.12, SG 1.0275
Bag with four astraea snails - pH 7.91, SG 1.025
Bag with pink dwarf Hawaiian feather duster - pH 8.02, SG 1.027
As you can see the salinities were all over the place! The poor fish was looking awful and was in low salinity. The shrimp and worm were in high salinity. Only the snails were close in water chemistry to my tanks. I put the two sexy shrimp together for the acclimation. Around 11:40 am, I put the animals in the tanks. The worm went in the 12 gallon; the rest went in to the 6 gallon.
The 3 gallon batch of saltwater for the 12 gallon tank had a temperature of 77.1 degrees F, SG 1.0245, and pH 8.18. The 2 gallon batch of saltwater for the 6 gallon tank had a temperature of 81.9 degrees F (I let it cool without the heater while tending to the 12 gallon), SG 1.0245, and pH 8.16.
It was not until past 3:30 pm that I got around to the cleanings of the tanks (which were now down about half an inch and two inches for the 12 and 6 gallon tanks respectively from the acclimation). For the 12 gallon tank, I tried to suck up the red planaria of which there are tons! I did not see any bubble algae (but I got those a few days ago). I did not mess with the Caulerpa as it seems it has died back. I hope the green polyps and orange zooanthids recover from that onslaught. I readjusted the feather duster which had fallen down. I scraped algae off the front glass. I put a quarter cup of aragonite in the bottom. I changed the carbon and RowaPhos which I do every two weeks. I put back almost all of the 3 gallons of saltwater I had made for the 12 gallon tank. I then removed more water from the 6 gallon tank, cleaned the glass, and put back most of the 2 gallons I had made for that tank. I have about half a gallon left over which I will use to help next Saturday with the corals that I had expected today.
I created these new pages for the new animals:
Clown Gobies
Sexy Shrimp
Feather Duster Worms
I did the usual water changes and chores. I removed a hundred or so planaria but made little dent in their population. I pulled some more Caulerpa from the polyps and removed some bubble algae.
The water test results for the day were:
12 Gallon Tank: 75.9 degrees F (heater broken?), 1.024 SG, pH 7.86
6 Gallon Tank: 80.4 degrees F, 1.024 SG, pH 7.98
Make up water: 76.9 degrees F, 1.025 SG, pH 8.35
On 10/11/08, I did the usual Saturday tank cleanings. Most of the animals are doing well. One of the new zooanthid rocks have yet to open in a week. The button polyps have four heads but only two have opened; the others seem to be rotting. One zooanthid rock only has one open polyp. I took a lot of photos in the last week but have not had time to process them as of yet.
The water test results for the day were:
12 Gallon Tank: 77.3 degrees F, 1.024 SG, pH 8.11
6 Gallon Tank: 77.2 degrees F, 1.0245 SG, pH 8.10
Make up water: 76.2 degrees F, 1.024 SG, pH 8.39
In the 6 gallon tank, I moved the button polyps to the back of the live rock. The purple mushroom coral had inflated over the polyp (the larger of the two survivors) so it was not opening.
I still have not processed the digital photos of the new corals from two weeks ago. I have no time!
The water test results for the day were:
12 Gallon Tank: 75.0 degrees F, 1.0245 SG, pH 8.19
6 Gallon Tank: 75.3 degrees F, 1.025 SG, pH 8.11
Make up water: 74.9 degrees F, 1.025 SG, pH 8.33
The water test results for the day were:
12 Gallon Tank: 77.5 degrees F, 1.024 SG, pH 8.01
6 Gallon Tank: 76.7 degrees F, 1.0245 SG, pH 8.05
Make up water: 76.4 degrees F, 1.0245 SG, pH 8.29
The water test results for the day were:
12 Gallon Tank: 77.8 degrees F, 1.024 SG, pH 7.82
6 Gallon Tank: 77.3 degrees F, 1.024 SG, pH 8.00
Make up water: 76.5 degrees F, 1.024 SG, pH 8.19
The water test results for the day were:
12 Gallon Tank: 77.8 degrees F, 1.024 SG, pH 7.97
6 Gallon Tank: 76.8 degrees F, 1.024 SG, pH 8.00
Make up water: 76.1 degrees F, 1.024 SG, pH 8.16
