If your plants are growing, then they will produce lots of oxygen for your fish. Since you are not adding CO2, then I don't think the surface movement will remove any CO2 that is produced from the fish. A little bit of ripple on the water surface is fine, but a lot of surface movement or waterfall (like HOB filter) will remove CO2.

Big Al's Online has most parts for the Aquaclear. http://www.bigalsonline.ca/BigAlsCA/ctl366...b_value_0=Hagen

I can't see why it can't be replaced... It might be too expensive to warrant changing, but ballasts can be bought at electrical stores. I also have a coralife PC type light with problems. I will take a few photos as I take it apart and do some testing.

Fake plants look good with fake fish... so if you plan to use real fish, live plants look better and help maintain water quality. Most fish stores or local members can help you get your tank cycled quicker with some used filter media (or the goo squeezed out of them).

If you can find a waterbed drain/fill kit, they are basically same idea as a python.

Ask aquagiant about cutting a new bottom... but I wonder about cutting the curved part for the bottom. http://albertaaquatica.com/index.php?showtopic=21394

I have never seen BLACK bugs in my planted tanks...

Called Planting Rocks... http://www.geosystemaquarium.com/geoeng/pr...ocks.php?link=4

I have had good luck with Giant Vallisneria, Naja grass (Najas conferta), Tiger Vallisneria, Giant Duckweed, Java Fern, Egeria naja, and Hygrophila. Hagen Geo-systems makes fake rocks that are pots to keep the roots from being dug away. I also use small (4 inch) chucks of shale around the base of the plants to keep them from digging. Hygrophila and Java Fern can be attached to driftwood as well.

I have found out that moving the plant from my 55g to my 90g had nothing to do with it flowering. Over the last few days I have been watching a new set of flowers come off another val in my 55 gallon. I think the reason they flowered was their light got cut in half (from 260 watts to 130 watts) for the last month or so due to a failed ballast.

Boom is going to Mexico for a week and he has a nice workshop

Princess Auto has cheap fans if you are lucky to find the right size there. If not a computer shop like Memory Express should have one... http://www.memoryexpress.com/

I have never set up a sump before, but with most types of plumbing I have seen, the return line is the big line and the pressure (pump) side is the small line... If you would have had the pressure line tee'd off, then you could return some of the water back to the sump with out going through the tank.

I also have a Milwaukee gauge. What pressure do you run your second gauge at? I had troubles setting a decent bubble rate until I raised the pressure on the second gauge. It just makes the needle valve a little harder to set. One possibility is that something (or someone) got into the tank connector while it was un-hooked. You should open the valve briefly before attaching the regulator to blow out any junk in the valve.

Sorry about your fish...

Old windows from houses are very cheap. We find them at the dump all the time. Calgary has a place called Tim's Reusables that you find buy old house windows very cheap.

I forgot about that 6 foot detail I also noticed that the 6 foot fixtures use the same bulbs as the 4 foot fixture as they are both 39 watt bulbs. Do they space out the lights or just stick the 4 foot bulbs in the center leaving the ends darker?

There is lots of other vals (10 or more) in the tank, but I have not noticed any of them flowering. This was the only plant I moved if that had anything to do with the flowering. The tanks sit side by side and share the same timer, so it is not a change in my lighting times. The only big difference in the two tanks is the 90 gallon doesn't have CO2 injected (yet!)...

If you take a juice-pop bottle (400ml or so) and add 1/8 teaspoon of ferts and fill with water. If you use half the bottle, you are adding 1/16 tsp. If you use 1/4 of the liquid, then you are dosing 1/32 teaspoon. Dash = 1/8 tsp Pinch= 1/16 tsp Smidgen = 1/32 tsp

5 x 39 watts = 195 watts / $390 = $2 a watt Coralife 48" FRESHWATER AquaLight Fixture - 4 x 65W 4 x 65watts = 260 watts / $260 = $1 a watt The coralife light comes with plant bulbs as well (6700K).

Propagation: Occurs via two mechanisms, sexual by flowering and asexually through vegetative 'runners'. Vallisnerias are dioecious, with separate male and female flowering plants. These flowers appear on special stems that can grow as much as 2 cm. (1/2 inch) per hour. The male flower spathe is short and releases male flowers near the base of the plant that rise to the surface pollinating the long-stalked female flowers. On fertilizing these coil and ripen underwater http://www.wetwebmedia.com/PlantedTksSubWe...vallisneria.htm Here is a close up of the flower which is about 5mm across, but the stalk must be about 30 inches long!

I recently moved a Giant Vallisneria from my 55 gallon to my 90 as it was getting to large for the 55. Tonight while working in the tank, I noticed these strange thin, round corkscrew type vines coming from the plant. There are 3 of them, but what are they? I thought Vallisneria usually spreads by the roots so I never expected it to flower

I find the best way is to get an account at Photobucket and upload your photos to there. Under each photo will be 4 boxes, click in the Image Code box, and then paste into your post the code you paste in should look like this, only with square brackets at start and the end...

Which LFS carry them? I have bought the hinges at Big Al's in Edmonton.
