There was just a post on this but the answers don't solve my problem. My tank (75g) won't cycle, 3 weeks in, heavily planted in aquasoil, ammonia never got above 0.5, not many water changes, no ferts, seeded with media from my other established tanks. For the most part I've got rainwater coming out of the tap, KH is maybe 0.25 to 0.5--if I use 20ml water it takes 2 drops to get to color change, immediate if using 5ml. Absolutely zero GH. To make matters worse, I used aquasoil as a substrate before realizing the water at the new house isn't the rock hard stuff I'm used to and so the pH is likely less than 6 (low as the test goes) and KH is zero from that tank and my others, lost the 0.5 degrees from the tap.

For the health of my fish (once the tank is actually cycled and I can put them there) I'm assuming I'm going to have to use something to increase GH every time I change the water? What about KH and getting this thing to actually cycle? What products do RO people use? Is epsum salts enough or?

I am used to the exact opposite of this problem so feel a bit lost. But not exactly stoked that I'm going to have to mess with parameters. Thank you for any input!

You are going to have to use a GH booster. I would use seachem Equilibrium. Epsom salt by itself is not going to work. Equilibrium has sulfur, calcium, magnesium, potassium, and some iron. That is 5 nutrients plants need and 2 that are often not included in fertilziers. The minimum GH you need is about 3 but your fish selection will eventually determine what GH value you need. As plant consume the sulfur in the GH booster some carbonates will be produced. I only see about 2 degrees of KH and that with some old snail shells in my aquarium is enough to keep my PH at 7.

You are going to need fertilizer to grow any plants and that will provided many of the nutrients bacteria need. Add ammonia and GH booster to it and it might cycle. If you add a small amount of food to the tank that should provide additional bacterial nutrients fertilizers and GH booster don't have. Also add about 2 PPM of sodium chloride to the water. Most fertilizers are don't have chlorine (another vital plant nutrient often not in fertilizers). Even with all of that I cannot tell you if it will cycle. If it does great. If not...

Then watch your plants if they are growing well they might reduce the ammonia to a safe level by themselves. If so you could add a single nerite snail to the aquarium. He would eat the food you add and help start the tank cycling without additional ammonia added. Then slowly over time you could add more animals (additional nerites or shrimp and eventually a few fish. The bacteria would slowly grow with the growth of the bioload. However you will have to keep a close eye on ammonia and nitrite valves and be prepared to do more water changes if needed.

That is the best advise I can give on this. I hope it helps.

Note on Equilibrium sulfate based GH boosters will not dissolve well in a small container of water. However they dissolve easily in 1 liter or larger bottles or if added dry directly to the tank.

Thank you that is helpful. I've been doing some reading on GH boosters and will go from there, interesting about the production of carbonates, my other planted tanks that have been running for years read the same parameters except no ammonia obviously. I was going to wait for this one to cycle before adding fertilizer but in this situation I see it makes sense to start now. Fish food and minerals will hopefully get it going, appreciate the help!

My tap water is 4GH and I like to get it to 6GH as my mg from tap is extermely low. So I like to even it out and get it closer to the 3:1 Ca:Mg ratio by adding 2dGH. I do this during water change. I use NilocG GH booster and add it directly to my aquarium. Usually in 2 hours most of it has dissolved maybe a few small pieces on the bottom. 4 Hours later all of it has dissolved. You can either add it to some water ahead of time or just directly to the tank.

For my CRS tank as they are more sensitive to water parameters I prep the water ahead of time using Salty Shrimp GH+. I let the water with the GH mix for 3 days before using in the tank. Now what I like about the Salty Shrimp GH+ is it dissolves litteraly in 5 minutes or less and I mean completely dissolves. This stuff is more geared towards the needs of shrimp though. Its Ca:Mg ratio is I believe 4:1 where as most other GH boosters are 3:1 Ca:Mg. Either way you need to add GH to your water.

If you were refering to the thread I started I am now getting nitrates. I believe my issue was I had too much Ammonia and with the low PH due to the buffering substrate I know it really gave the bacteria a very hard time to get going. Once I did a water change with some tap, got the ph up a bit and also helped lower the ammonia, it kicked into high gear
