Re: 120 x 55 x 55 the 3 week update and trim!
I'll do my best to answer Mike.
ADA amazonia only...no powder.
Co2...on 2 hours before lights on. Drop checker only dark green via boyou inline diffuser
Lights...2 x 54t5 for 5 hours. Currently about 10cm from the water. Geissman lighting is by far the best design I've seen. Efficiency is amazing.i.e reflector design
O2 added at night via raising the lilly pipe...rather noisy though.I shut the bedroom door.
Water changes 2 x 50%weekly.seachem declor added. Straight from tap...although i can control the temp. of what comes out of the hot water tap, via a controller on the boiler...especially with winter coming, this is great!
ferts Elos K...3 squrts daily TPN + 10ml every other day. Quite low ferts for a big tank.
Vac areas i can get to. Shrimp crud is quite a lot.
Filtration is really low. Just 1 x JBL 1500LPH. Loaded with seachem carbon, seachem phos remover, and 200ml purigen.
No heater and maintains 21/22c...lower in the mornings.
about 50 amano shrimp, 25 ottos, and about 25 cherrys, 3 CRS and 1crs ss+
Fish get fed bloodworm every 3 days or so.
Trimming as required.
I'm not really sure why my plants grow so quick in the early stages. It's always happened, even when i first started. There's more an element of luck than science. I just dont get the science part.
I'm finding the bigger the tank, the easier it is. I do have slight GSA on some of the stones and a small amount of diatoms, but that's to be expected. Diatoms are no where near as bad as I've had them in the past, and this was the one thing i had to master and get on top of.
I think this just about covers everything i do.
