This tank was torn down and rescaped January 1st but Crypts typically grow great in this tank. Had massive blooms of nearly every algae known to man for the first 30 days or so, but this has subsided over the past 30 and things are clearing up. I bought this plant shortly after rescaping and it's done really well until the last few days. It's probably 20x the mass from when purchased, sprouted several new leaves and seemed well on its way. But over the last couple of days I've been noticing white discoloration and a texture change.
parameters and dosing info:
pH 7.3 degassed
TDS +/- 160
25-50% water changes weekly
Substrate is inert, CO2 reaching a .8 pH drop, lighting is a Fluval Planted 3.0 peaking around 70% in a 24" deep tank plus a Marineland LED. Lighting is on for 9 hours and 40 minutes a day, with an hour long siesta in the middle. It is a tall, very shady tank, so trying to work out lights to reach the lower places.
FTS taken last night:
Using GLA fert recipe which I thought would be lean but adequate. Can post the amounts of each, but math is my weak point.
K2PO4 -6g (recipe calls for 3)
mixed into a 500 ML bottle and dosed at 30 ml daily
mixed into a 500 ML bottle and dosed at 15 ml daily, used to also be 30 ml/day but shrimp appeared lethargic after dosing so I'm tinkering with cutting back.
A cursory Google turned up nothing so hoping someone here has knowledge or experience with this phenomenon. Thanks!
Hi I’m guessing it’s a bit shaded.
The plant looks like crypt spiralis red or tiger. The green stripe is usually more evident on the bottom of the leaf which makes me believe it’s either not getting enough light or the leaves are coming in twisted and that may be due to Ca and/or Mg, or maybe even due to reaching for light.
