The supplier I use recharges CO2 cylinders a lot of the cities commercial fire systems and the fire service, so I think it's pretty safe to say his level of inspection and quality control is at least as high as the over priced BOC. You obviously work for BOC. You have not made a single post on any other subject in this forum. It's time your account was removed.

I use the stuff from spotlight, get the stuff on the big roll, not the one in plastic bags. The plastic bag stuff sometimes has mould inhibitor in it.

Try mussel, never fails for me.

Make sure they understand that it is the top you need dead flat. They will effectively be building it upside down. Normally if you were making a bench (which is basically what they are doing) you would be more interested in getting the feet flat and even (so it doesn't rock) and then the top gets welded on. When making a stand you need to lock the bottom to the ground when you weld it to stop it from warping when the welding heats it up

The age of the tube is probably the important factor, most have a 1/2 live of 6-9 months but as they get older they keep giving off less light and the colour changes. So use the newest. Looking online the power glo is slanted towards marine so will have a higher kelvin rating and the aqua towards plants, so the power glo will be bluer/whiter to look at the aqua glow more yellow. The bluer tube will bring out the blue colours in your fish and make the tank look brighter, however plants like the redder/yellower light so would grow better using the aqua glo. (assuming the tubes are similar age).

I have a couple of solenoid taps too if you can't fine any. Put them aside for a future project. Sig changed :lol:

Washing machines have solenoid taps, you could buy a $1 washing machine off trademe and get the taps out. I wouldn't bother with getting both hot and cold water, if you have the feed rate down slow it wont shock the fish. In fact would be easier on the fish if you do the water change over a couple of hours Yes, just plug the adapter in to the timer. You will need a tap on each tank anyway (in case the tank is empty, etc) so use this to control the flow.

Would be interested to know why you are such an expert? Are you on BOC's payroll?

Move up north and you'll wish you only had that many. We get a few as well, having a dog and 3 cats doesn't help either. Some years I mix up some ripcord and spray it round where the flies tend to hang out, lights, beams, etc. It seems to keep the numbers down for months. If you do this just make sure you don't spray near your tanks and if your really worried cover them up. Ripcord is good because works well and since it's mostly water it doesn't float round the house like spray can stuff does.

I like that "will need a couple of people to lift it" :lol:

Sounds to me like someone in the UK has a stake in BOC. A CO2 cylinder is no more unsafe than the LPG cylinders we all leave rusting away under the BBQ on the porch except that the gas doesn't explode and burn. All cylinders are stamped with the expiry/test date, so this whole "responsible for testing" thing is rubbish, just like an LPG one, when you go to get it filled the filler checks it hasn't expired, if it has you pay $30 to have it tested. My bottle cost me $120 to be tested and have fancy valve put on. plus $25 every 6 months for a refill. So over 5 year life it's going to cost me $370. BOC (prices in fist post) $12 month and $30 refill every 6 months, works out to $1020 or 3 time's as much. How many time's more expensive does something have to before it counts as extortion.

Interesting, I use scrappers around one a month on my marine tank, there is no better way to remove Coraline algae that I know of. Have also cleaned a lot of paint off windows and never managed to scratch the glass. Are you sure it's not linbide scrappers? I've scratched and broken plenty of windows with those

What do you include when you say "normal cleaning"?? I always use a glass scraper, same as painters use to remove paint from glass, that should remove your residue

I borrowed a regulator from a mate that had one just sitting round. I don't think getting a fitting is a big deal, he is a fitter and turner so maybe he did make it. But you must be able to get fitting's that attach otherwise they wouldn't be able to fill the bottles and if you can get a fitting you can attach a regulator to it. Don't think you could add soda stream water to the tank, well you could but if you added it fast it would screw with your pH, I would think it would be pretty much impossible to add enough to make much difference to the CO2 without it changing you pH. I guess you could try putting some air hose in the cap and running like you would a DYI yeast

Done it, works fine, but the bottle doesn't last long and are expensive to get filled compared to a larger bottle.

Personally, I'd be moving the filter and fish etc to another tank (or even a bucket, rubbish bin, storage box etc) and completely stripping and rebuilding the tank. The end result will be far better plus it will be easier and faster then stuffing round trying to syphon the gravel out.

Those ring can't be fitted now, it wont pass your warrant with them fitted. I used to have them installed on my car but have had to remove them, luckily for me my wheels still fit, unfortunately the spare wheel doesn't so I carry one of the rings with me.

Did you ones you got from the last hunt survive?

IME all the injection methods (Kalk, lemon Juice, vinegar, etc) just cause the anemone to break up and spread. The only successful method's I have used are to completely cover the whole Aiptasia with kalk while the rock is out of the water, or natural predators like butterflyfish

Plus they have constant UV on them

My Dad has a couple of tanks that he stores in his shed, I used to use them when I was a kid (20+ years ago) he fills them up every year or so when he give's the pond a spring clean and they are fine.

Repairing wouldn't be that hard but you would have to completely replace any panels that have swollen, a sure sign of water damage. There are lots of ways they are held together, glue, staples, dowels, pins, the only way to find out is pull it apart.

Mostly yes, but not in reserves and size/catch limits apply, Puna, Kina, crays etc etc.

It also depends on what you want to grow, some plants particularly the redder one's don't grow well or at all with out strong light, fert, and CO2. None of it needs to be expensive, I used to use dalton's aquatic potting mix under a layer of gravel for substrate, this gives you all the fertiliser you'll need plus being in the substrate rather then in the water it doesn't cause algae, cost about $20 a bag which is enough for 2-3 4 foot tanks Used 2 x 4foot batten light fittings and daylight tubes from electrical wholesaler, lights ~$30 and tubes less than $10 each. Fire extinguisher converted, $10 for old bottle, ~$100 for conversion and certification, regulator ~$100.

Green water is a balance problem. Either too much of something or too little, usually too much nutrients or too little plants to use up the nutrients. Most likely some husbandry would fix the problem, water changes, syphoning gravel, cleaning filter and/or adding more filtration. Things like algae rid are a chemical band-aid and will at best only be a temporary fix.
