Sodium Bisulfite will remove the oxygen from your water (Prime, Safe and Amquel Plus, among others). Especially if you have drained 75 percent of the water and dump in enough for the whole tank. I would rather introduce the dechlorinater as I fill the tank, with the nozzle hitting the water at the same spot as the replacement water. When the tank is full, the container with the declorinater is just getting empty. The air valve on the end adjusts the flow. I fill the container up with tank water and add Safe. Safe is the dry form of prime. The pvc is to stir it. With Safe you use 1 tsp per 50 gallons. Safe also handles the free ammonia. Check it out in these videos.

by ScorpiosWifeOK, so the entire thing took about 20 minutes to build! Of course, as I suspected, hubby wouldn't let me play with sharp objects. While he was cutting, I removed the filter, gathered some marbles for the sides & then realized I forgot to take pictures of the material before we started. Oops. I didn't remember till he had already cut the mesh, egg crate & had started with the zip ties. Hubby measured & cut the egg crate as close to the inner dimension of the tank as possible. Then he cut the ...

by cichlid1409So, I've been wanting to upgrade to a LED fixture on my coral tank for a while now. As I looked online at all the fixtures I found they were either too much moolah or not bright enough IMO. So I decided to pull the trigger and try to build my own. After digging around online and figuring out a game plan this is what I decided to go with: 12 - 3w cree XP-G (white) 12 - 3w cree XP-E (royal blue) 1 - meanwell 35-700 driver 1 - meanwell 60-1050 driver 60 degree lenses 10in X 10in heatsink Custom ...

by jarrodadenI was looking for a way to automate the air removal from the siphon tubes on my overflow box without running risk of pumping the siphon tubes empty. I was also worried about siphoning them dry during a power outage via the air tube.
Using an aqua-lifter pump, I came up with a solution.
Attached is a DIY video link.

I had a problem with water squirting out the anti-siphon hole on my wet/dry outlet and Dustin at Houston Aquarium Warehouse gave me this idea.
Simple and easy to do.

by ZebvanceI had a black background on my 240 from Petsmart. I had a lot of problems with it. Water would get in between the background and the tank when I would service the tank. It got on my nerves enough for me to rip it off. I ended up having the idea of laying down one big piece of vinyl (a big black sticker) on the back instead of painting it. I am not a very good painter and I didn't want to do something that permanent to my tank. So I picked up a 96x30 sheet of vinyl from the local decal shop...
