I could really do with your knowledge here!
First, a quick explanation:
I've been keeping/breeding fish for years (had around 45 tanks in the fish room when it got out of hand), but Im far from knowledgeable when it comes to plants.
I've had many planted tanks that have thrived in the past, but I've been lucky enough to never do anything other than stick the plants in and watch as it grows.
My situation at the moment, is I have 2 100-110g tanks, which we recently (about 3 months) converted to planted tanks around the same time.
- The tanks have around the same stockage (20-30 small community fish, guppies, platies etc)
- The tanks have the same input water when water changing (75% waste RO
water which has gone through the two carbon pre-filters and had tap safe added, and 25% ro
water). I had the ro
unit left from the marine tank so didnt want to waste it
- Both tanks get fed around the same ammount.
- Both tanks have a few home made root tabs using a recipe from another forum.
One is thriving , one is dying
My guess is that either a macro or micro nutrient is bottlenecking my tank?
Firstly, a picture of the healthy tank:
Notice this plant in particular: (The holes, I think are a potassium deficiency? or my snails, but its still growing like mad)
Now compare the same plant to the one in my other tank that started a similar size:
The leaves are about 2cm long rather than 10
In my dying tank, I find the tops of the plants grow fine on most, but they all shed/lose their lower leaves, leaving long leggy plants with bare stems (below)
The only other cause I can think of other than a lack of a certain element is the lighting? My thriving tank has a home-made led
unit, currently pumping out about 50w of white led
's and 50w of blue (currently on lowest setting, but can be cranked up to 450w so skys the limit). My poorly tank did have 2x 5 ft t8 bulbs on it, one daylight, one slightly redder (name wore off it), but I've now dropped it down to 1 to slow down the nutrient consumption if it is the bottleneck.
Any ideas guys?
Any help is much appreciated!
