"hhhhmmmmm Interesting information Vlad. Deep water may be better. Then again perhaps the grow towers would be even better as I understand that they also act as a bio filter like that of the media beds. I'm just not as versed in the towers yet.…"
"FYI: Aqualibrium system (http://aqualibrium.com/)I got one via a friend who supported their Kickstarter. I'm glad I didn't pay for it.
Its pretty, and it does work/function.
However, it is obviously designed by people who didn't try…"
"If you hadn't, you should probably do a water change of some non-tiny amount.
You added a pretty large volume of fish with the catfish. Even if you weren't feeding them much, they're still putting out waste since they were eating…"
"I did do the media test for lime. have more plants in seeds under the stone just waiting for it to come up.
Did you see my siphon time? 6 minutes 49 seconds fill time and 1 minute 55 seconds drain....what you think?"
"I wound up putting 2" Styrofoam around the sump. I can only assume it helps. I boxed in my GBs from the ground up with 1" foam and covered them with a mylar low tunnel with the grow lights inside for heat at night. I only heat the GH…"
"Deborah, I have 35 1/2 barrel beds that operate on their own timing. I have found that all I have to do is look into the siphons each day to check the water levels. If the water is somewhere in between the top and bottom of the drain, it tells me…"
"Thank you for your advice. I have the test kit and will start testing more regularly. Will definitely also take a look at sludge buildup and explore adding to the fish population if necessary/ increasing cycle speed. All things…"
"This is just my opinion I haven't ran into this problem before. I don't think its a lack of nutrients (fish). I would say that it has to do with the depth of your bed. Here why. Personally I've grown in bigger growbeds using less…"
"That will figure will depend more on the amount of input feed going into the system and what plants you have in those media beds...
You may find that you need additional filtration between the beds and the NFT to operate them successfully and…"
"I built a 3'x5'x4" box painted black with a double pane glass front with 200' of black irrigation hose inside. The temp got really hot in the hose but as it circulated it didn't seem to keep up well. I ran it during the…"
"Def normal to have to add water -- lots of evap from low humidity --10% not unusual. Not sure how to answer your other question except generally all the beds will eventually cycle together, occasionally, so your sump tank and FT need to be able to…"
"Thx Jim for the info. Some of this i had started but just didn't get it done in time. Im looking fwd to killing this next yr lol I just added four more grow beds so I have a total of 8 now cant wait to get fired up again Thx for all your help…"
"Here in So Cal I'm paying $3.35 each for fingerlings. They are pretty good size (4-6") and very pretty Blue Channel Cats, but I am more interested in delicious than pretty. Next time around maybe I'll see if I can get them shipped…"
