DO you clean the ADA AS when doing water changes? I have AS and do not vacuum the gravel. My AS has been in my tank for about 13 weeks. No probs with clarity.

No.

BTW, I have a dozen tanks with ADA As without issues as well.
It's just too large of tank to deal with the ADA AS.

How would you make a commercial substrate?

Soil, boil, sand, & a pinch of KNO3, KH2PO4, CaCO3. Sprinkle in some peat and perhaps Laterite for good measure and then leave it out to dry. Oh, & then add some twigs for that good inner 'organic' feeling?

Regarding your rash Tom, I have a new 60cm set up using ADA AS Amazonia powder, and I have noticed that if I have any kind of cut or abrasion on my hand when I dip it in to the water, I get a tingling sensation. It almost feels like a tiny electric shock.

That aside, I have found my water clarity to be perfect apart from a slight yellowish tinge in the first week. ADA AS is also superb for adding steep slopes that will stay put, making it ideal for aquascapes outside of gently sloping substrates.

I've tried AS once and I am not happy at all with the outcome. I still have it and will probably try it again---but I won't be recommending it!

Here six months as I have started the tank on 165 gal. For a ground I used Power Send and Aqua Soil Amazonia. It absolutely agree with Tom about that that next time I many times shall think before I shall take for a ground materials ÀÄÀ.Ïîñàäêà of plants simply pleasure and if it is necessary to pull out so it simply punishment. The dust from a ground costs 2-3 days, notwithstanding what there is a powerful filtration. I have no anything against production ÀÄÀ.Substrat very well works. But next time at start I from above shall give a layer of 2-3 sm thickness quartz or other sand. I think of purchase Diatom filter. There can be it will help me at change aquascape with the future.
