Maynhia,

You should think about your future expansions as far as more growbeds, with a bigger pump you can always slow down the water flow with an inline valve.

Thx Dave,

Did you get my message on sunday?

Maynhia,

forget my rule of thumb 15/45 for winter. Someone suggested cycle the fish water one time each hour. I like that rule.

for my 300 gallon tank I use a danner model 18, 1800 GPH. talk with Sheri, she can give you the correct info.

Hi, anyone who can tell me how big of a pump I need to get for a 200gallon water tank hooked to 4 grow beds which are 75"LX32"WX11"D? and still maintain the 15/45 rule of thumb?

I have 3 extra pumps that are 185gph but it would just be too much hardware to use them. Thx

Lynn, ours are in an aquarium that's kind of a show tank, too, so I wanted something that looks nice. I started with plain construction sand (boiled to clean). It was good for a while and they loved it, but it was too light and was hard to vacuum because it would come up with the waste. I now have a heavier silicone sand, which is very nice & they like it, too.But it depends mostly on the size of your fish. Ours are between 9" & 12", so they can pick up pea gravel; I could just leave gravel on the bottom.

Tilapia will breed even with no substrate when the conditions are right. If you use nothing, it makes it easier to net out the fry later. I use a substrate because, as I said, it's kind of a show tank, I like the natural environment, and because I'm just a pushover.

David I hope you mean .3 and .5, not 3 and 5. If that's what you mean, the smell is probably the algae, which will make the water cloudy. It's a "green" smell, kind of pond-smelling. The algae is consuming the nitrates because there isn't enough plant to consume it all. Usually when you see water like that, the sides of the tank will feel slimy because algae is starting to grow on it. This is all a normal part of nitrification. When the cycling is done, your amm. and ni. will be 0 and your nitrates will be the only measurable thing. Then when you have enough established plants, that will go down, too. Things that will minimize algae growth: a dark environment, lots of aeration, plants and water changes.

Has anyone here done anything with bsfl?

I went from a 250 gph pump to a 560 gph, added one more grow bed. I think this is all I could do inside, I have much more outside for April.
