I'm just starting out with my big tank (see signature link) and I'm wanting to get the growth rocking along with all the plants in there to get them established. I'm thinking the co2 I'm adding isn't quite cutting it now that the 2 x 150w 6k MH lamps are on for 8 hours a day. I'm seeing a bit of growth in the last 2 days (first 2 days of MH light) but that had pretty much started with the single 3' powerglo and the MH light has just sped it up a little.
Should I add some excel for a few days to see what that does? I haven't had any pearling yet so I assume the co2 levels aren't quite right. I've been adding flourish comprehensive at the recommended doses for the last week (twice). So far no problems with algae except maybe a little bba that was a hangover from the last tank that survived the bleach bath before the new tank.
Dimensions & volume of tank - 1520x760x610 - 690L (about 100L is substrate/aquatic mix)
Lighting - T8 36" PowerGlo (12 hours a day) 2x 150W 6k metal halides (8 hours a day)
Substrate - Daltons Aquatic Mix & Daltons number 1 sand to seal, river rocks on top of sand.
Plants - Red Rose Sword, Osiris Sword, RoseXOzelot Sword, other unknown Sword, Green Lotus, Dwarf Sag, Crypts (not sure which flavour), cuttings of Ambulia, Hygrophila polysperma and Ludwigiia something (goes a nice red / green mix).
Fish stocking - 13 panda cory, 4 apisto agassizi, 2 GBR, 3 L140, 4 p. scallare - no snails as yet.
Ferts - currently using a nutrifin DIY co2 ladder. Dosing 2 times a week with flourish comp.
Goals - To have a tank that is full of growing and healthy plants. I don't mind doing the work to keep it that way it's just getting there in the first place that eludes me.
Problems - New tank so nothing yet just want to make sure I get the best out of my plants as soon as possible.
