Some small additions to the tank :
Added some more bolbitis to the back center , replacing a few tissue cultured wendti which melted back into nothingness .
Some more Java Fern went into the back center right and along the right and left sides ; again to replace vaporized crypts and a few strings of Monte Carlo that went someplace .
Couple more Buces on the root and back left lava wall .
Most of the larger crypts are showing new growth . As are a few of the Anubias that melted . Think maybe they had some sort of transplant shock that caused them to drop leaves .
Still squashing snails .
The floaters in the tank are doing real well so far . Frogbit’s developing long roots , riccia’s becoming a nice pillow , and the hornwort has decided to spend its’ time trying to fill up the tank .
The substrate filter pickup is working pretty well , though there’s the expected mulm buildup starting . I’ll let it build up for a few weeks and then start siphoning what I feel is excessive during the bi-weekly water changes . A bit ( or maybe more than a bit) here and there won’t hurt anything .
Ran the diatom filter for a couple of hours after adding stuff to clear all the floating organics out of the water . Amazing how clear it gets the water .
Waited to begin ferts. until the cycle completed , so began yesterday . Adding 30 ml of each :
K2HPO4 mixed in a solution of 1.75g/250ml of water
KNO3 in a solution of 15.5g/250ml of water
Microplex (for traces ) in a solution of 4.25g/250ml of water
Chelated iron in a solution of 3.4g/250 ml of water
Used a cheapo Harbor Freight scale to do the measuring.
Proportions are from here : Rotala Butterfly | Planted Aquarium Nutrient Dosing Calculator
calculated assuming low light EI , 10ml dosage/10 gallons ( or 1ml/gallon of tank water)
Using a plastic graduated cylinder and making a solution for 1ml/gallon makes dosing pretty much brainless . Fill the cylinder to the level of your tank’s volume and dump ……. done.
Been using this for a while now in 16 other low light/tech tanks and it seems to be working OK . No problems save for 1 20long that gets BGA occasionally . But that tank is pretty heavily stocked .
I’m using a 30 ml. dosage to compensate for the amount of water volume displaced by the hardscape . Probably getting too concerned over this , but better too little than too much at this point.
I’m thinking of introducing 8 or 10 RCS into the tank , possibly next weekend , if everything stays stable . The only concern I’ve got is this crevasse that was filled with substrate , but pretty much opened up thanks to gravity . I’d like to fill it up , my thought being that if something can to get into a tight area ,get trapped , and die ,
it will . Any ideas as to possible fillers?
And the obligatory full tank shot .
