Mine seem to close up if you walk past the tank in a grumpy mood. So, no surprise they'll close up if you put them in a new tank.

Yeah, should be fine to leave it overnight. I just go collect water whenever I get a chance and dump it in a 200L barrel then take the water changes from that. The water's been in there for 2-3 weeks.

Why why why why WHY would you use customwood? Horrible stuff, I absolutely hate it. NOTHING for fish tanks should ever be made of custom wood. Even with relatively tight fitting lids just the moisture in the lid destroys it. Let alone if you spill some water. Ok, done with my rant.

Instead of just drilling a hole, see if you can find some of the plastic air flow valves...Ummm...Look like a T with an inlet on on end, a screwy bit on the other and another inlet on the other side, cost like a buck. Or something similar to control the amount of air going in. Lets you just turn the screw to adjust the height of the water in the overflow. That's what I have on mine. Might need to drill two holes, one for the valve and another as kind of a coarse adjustment otherwise the valve, at least in my case, doesn't flow enough air on its own wide open.

I've started heating mine, I just throw a 150W or something heater in the barrel I store my water in the night or two before. That way I don't muck around with adding the water slowly to keep it from dropping too much.

I'm using a Laguna PJ5000

There you go. Hard to get a tape measure in to measure it.

My tank has a 25..No, just measured it, looks like 32mm overflow and my pump should be doing somewhere around 4000 liters per hour. It's pretty close to the limit for the overflow.

Should have gone in the private trade and exchange, Dogmatix. That's what it's there for, for sale posts don't belong in this forum.

R.I.P. Green Terror. AKA, Big GT. Born early 2004, died March 2005. 19 CM/7 Inches nose to tip of tail. On a happier note, the gouramis don't seem to be upset with me for attempted negligent homicide. All of them seem fine except a few scrape marks and ruffled scales.

It's not a standing wave though. It bounces back and forth across the tank which would shift water over most of the tank. It wouldn't create as intense a current as a stream, but the lesser current it creates would be practically everywhere in the tank. I'd consider one if it was cheaper. Maybe around the price of a Wave2k.

On the topic of dead fish, looks like I'm going to lose one of my green terrors. He was being chased around the tank by the other one, I'm not sure if he's just totally exhausted from being chased or if he's sick and that's why he was being chased. But he's just laying on the gravel, occasionally drifting around.

Hmmm, I know I'm forgetting some...AAHHH!!! *Races out to check on the tank of pearl gouramis and finds it totally drained* It looks like most of them will be ok. Getting a 100% water change, but gouramis can breathe air. They're just a bit scratched up. No dead fish at the moment anyway.

I wish people would make up their minds about them. Ask 100 people about them and the replies will be something like... They're harmless... They eat your corals... They're good scavengers... They kicked my dog... They're harmless... They ate my blue tang and made prank calls to the Cook Islands... They're harmless, just a symptom of overfeeding... They ate my cat! And so on...

If you do, I'd like a few.

Should be fine putting the sump on the carpet, I assume your floor is reasonably level.

There's a pod in the middle of the flatworms.

Get them from someone with a marine tank, if they have arefugium you could just siphone a bunch of water and a handful of macro algae out and they'll breed. You're in Auckland, there are about a billion people up there that could help.

It's peat. Which is basically the accumulation of plant matter you get in a bog. SOmething like $10 for a 10 lb bag. "Where's the peat?" should do. Or just go find it yourself, it'll be with the rest of the bags of soil. Not sure on the exact process, but it adds tannins and other organic acids that lower the PH. Depends on the peat and the size of your tank, the flow you have going through it, etc. Generally a couple handfulls are needed and the amount it lowers your PH depends on a lot. Just adjust the amount through trial and error, if your PH has settled higher than you want it, add more to the filter. Doesn't really matter, In the last container with some filter wool to catch any fine particles coming off it should be fine. If there's enough room. In the last two if you need more room. Hmm, in theory it can, but even if you put heaps in your filter it's not going to drop the PH that quickly even if it does go down to 5 that the discus won't probably be able to adjust. No, once it's dirty and exhausted throw it away and replace it. Should be able to. If they have bags of dirt, they should have bags of peat.

Best thing I did to get rid of algae was kill the flatworms...I don't get it, heaps of hair algae, cyano, give it a dose of Salifert flatworm exit, water change, carbon. The next day the cyano was noticably disappearing, a week it was gone except for a few patches. In a week the hair algae was noticably disappearing and in two weeks almost totally gone except for a few patches. I'm pleased, but confused. Not really helpful, I guess.

It would if the energy wasn't being lost. That much water moving back and forth, up and down through the rocks, against the glass, etc. The pump is only what? 18 watts? I'm impressed that little manages to get a 1-2" high wave bouncing back and forth. I think on the same tank to double the wave height you'd probably have to quadruple the energy.

My two GTs are pretty well behaved.

You can clean carbon, I don't remember the exacty details but it requires putting it in an oxygen free container and heating it to something like 1500°C for long enough for everything it's absorbed to evaporate and then be pumped out of the container. Obviously, not exactly cheap or easy to do.

I wouldn't have a ballcock or float arrangement or anything like that in the sump, just another overflow there running to a drain should do and you control the water change rate with a valve running fresh water into the tank. IMO, it's more foolproof that way. Unless I'm misunderstanding what you're talking about?

I'd love a jag...If I had a tank for it to have on its own. But then I'd be annoyed at having a tank with only 1 fish...
