myhui, use tap for the 1st 1-2 months for the water changes if you use the ADA. Then use the RO/mix/blend thereafter.
You are just wasting the RO water otherwise for the start up phase.
I see. Thanks Tom. I just started reading your book, and have signed up for your paid forum over on the Barr Report under the same user name.
Here are two videos taken a week apart:
The newer video doesn't look good, and now there are even fewer plants in the tank since some have died and I've had to remove them. I'm not going to add fish yet, if ever, since ammonia level is still too high, plus the plants aren't doing well.
Did I make an irreversible mistake by mixing the ADA Amazonia soil with their Power Sand at the start? (4 parts soil, 1 part sand) The plants aren't growing roots, and I suspect the soil is just too loose due to the sand in between the soil.
The tank gets 3 hours of direct sunlight every day. Is that far too much for a low tech tank still in the early stages of cycling and with not enough plants (since some plants died, not because I didn't start off with enough plants at the beginning) and no fish, hence no waste for plants to absorb?
I've started doing 1/3 water changes bi-weekly, using my own RO water. I hope I can rescue this tank, and eventually get it ready for fish.
I have ordered a bag of crushed oyster shells
and plan to sprinkle them into the soil.
I'll do what I can to rescue this tank, unless you tell me the soil is simply no good since it's mixed with too much sand. At the same time, I'll start growing my Hemianthus Callitrichoides "mats" based on your thread back in 2008
on an empty acrylic tank in the same location, and eventually that'll be my main tank and I'll transfer what I can from this 60-P to there.
