I think I am there. I let my PH crash and lost my progress and then about a week ago, I corrected and this is the first time I have seen 0 ammo 0 nitrites and measurable nitrates.
Here are my numbers for the past week or so.
Date PH A Nitri Nitra comments Days
07/17/13 6.0 8.0 0.25 0.0 added 3 palms of sodium bicarbornate 26
07/18/13 7.5 6.0 0.50 0.0 added 3 lime stones to grow beds inflow 27
07/19/13 7.2 4.0 2.00 40.0 28
07/20/13 8.2 1.0 5.00 40.0 added 2 caps ammo, removed two stones 29
07/21/13 6.8 2.0 5.00 20.0 Put 2 stones back, added 1 palm of soda 30
07/22/13 7.2 1.0 5.00 40.0 added 1 palm of soda 31
07/23/13 7.2 0.0 5.00 40.0 added 1 cap of ammonia 32
07/24/13 6.8 0.0 5.00 40.0 added 1 cap ammo and 1 palm soda 33
07/25/13 7.2 0.0 0.25 40.0 added 1 cap ammo 34
07/26/13 6.8 0.0 0.00 20.0 35
If you guys give me the OK, I will add "Shiners" (bait fish) to the fish tank and continue testing.
When you can dose ammonia to the tune of 1-2ppm and within 24 hours have BOTH ammonia AND nitrites back down to zero, AND YOU CAN DO THIS CONSISTENTLY 3-4 DAYS IN A ROW...you can then consider your cycled
once you do get fish (after following Vlad's advise), don't swing your ph by more than a couple of points (tenths) in a day or you'll be stressing your fish
With a 150 gal FT and 2 days of dosing getting a zero Ammonia and a zero nitrite read on the second day, I'd say yes to you being cycled. Listen to Vlad's advice though and go for 2 more days of ammonia dosing.
Thanks guys. I guess I will run it a couple of more days. I will go out tonight and dose it with two caps and see how that works out. I have discovered however, I need to find a way to reduce the temp of my water. I talked to the guy with the Shiners and he tells me I will kill them within an hour at the temp I am running . He has a chiller on his tank and takes it down to 65 degs. I have done a little research and this would be a good temp for a lot of fish and would allow me to use more varieties. I certainly don't have to take it down that low, but I know that 90+ degree water is not a good thing. I am thinking a small refrigerator with a heat exchanger inside with line off the pump through the exchanger and back to the tank. The frig has thermostat so I could have some control. I am just not sure if it will be enough.
As far as PH goes it seems to want to gravitate at 6.8 if I just leave it alone. I was bumping it up for the nitrifying bacteria's sake. I am not sure, but I may not have to mess with it. I intentionally did all I could to have as neutral as a PH as possible when I set my grow beds up.
I do not know what I am doing, but I researched a lot, asked a lot of questions and followed their advice. Thanks again for yours. It will be heeded.
Eureka! I do believe I am cycled. As suggested I dosed my system everyday taking it to about 2 PPM Ammo and 24 Hrs later she is reading 0 Ammo, 0 Nitrites, and 20 Nitrates. Today was the 4th day with such results. I am happy. Now it is time to go get some fish to kill. Today I started putting together my DWC that looks like an NFT system to add on to what I have. Wood work has been done, now the hard part about drilling all those holes in the 4" PVC.
