Hi.
Total newbie here, so apologies in advance!
I've been doing the research but couldn't see much about holding tanks.
I've been gathering plants in a 200L holding tank for about 3 weeks now and should hopefully be doing a final scape and setting up the tank at the weekend. There's about 35 plants in there and I've been keeping the light low,(2x 39w T5s for 4.5hrs) and adding 50% Ei fertz and doing a water change every 3 days. Filter is a FX6 with a full width spray bar.
I've discovered in the past 3 weeks that my Ebay cheapo regulator is pretty uncontrollable and am replacing it with a CO2 Art dual stage one which I should hopefully receive tomorrow. The crap regulator didn't stop me trying to get the CO2 drop checker to go lime green over a 2 hours period ready for the lights on. I'm temporarilly using a in tank diffuser and found that even if I let it take 3 hours to turn lime green by the end of the 4.5hr light cycle it had gone more yellow. This happened yesterday and the plants obviously were not impressed and shed a load of decaying leaf matter. My KH is 4 and GH is 6 according to the NT lab test kit and there's no substrate. PH goes from 7 to at least 6 when the CO2 is on, (my test kit doesn't measure below 6).
I'm pondering whether
-on a short 4.5hr low light, low fert growing cycle, the plants maybe grow too fast with lots of CO2 and start dying after they run out of fertz?
-There is probably a degree of leaf die off from emersed leaves being replaced with submersed leaves.
-I probably should have done daily water changes?
-I put too much CO2 in and turned the water too acidic?
Any tips on what's going on here please?
Thanks!!
